I love the BT 100 motor very reliable. It does get hot sometimes in extreme summer temperatures. The vibration on the motor is very minimal. I have over 1600 miles on my motor with no problems I run 91 octane and synthetic oil at 32 to 1. My usual ride is usually around 30 miles with a couple of breaks.
Extra interesting vid. on the BT fuel vapor lock issue. This parallels carb. fuel systems vapor lock problems in older automobiles. I suggest some of the shiney foil covered heat reflecting ceramic fiber tubes available from Summit or Jegs. Split the tube lengthwise to slip on from underneath the fuel valve, filter & fuel line, & loosely tie it on w/zip ties. You should still be able to view the line & filter from above without removal of the radiant barrier. I believe you are correct in isolating the carb. with a thick, heat blocking base insulator gasket. Rubber hose mounts do the same thing. Also the "latent heat of evaporation" characteristics of gasoline really cool a carb throat down during high demand. I appreciate your attention to details in your videos, Thanks Mr. Hover!
As always, great video editing, great information and very enjoyable rides... I always picture myself riding along....I haven't built a motorized bike for a minute but I will soon build another one... I miss the VROOM VROOM feeling and sound of the engines...!!!! I would love to buy a bike from you since I don't have the time to build one since I'm on the road 3 weeks out of the month...!!!!
I ran into the same intake heat issue with mine. Unfortunately, standard intakes wont fit due to the oddball 35mm spacing. What I did is fill the existing holes of 40mm intakes with JB Weld and re-drill for the 35mm spacing I needed. Works especially well for adding a reed valve. For windowed pistons, 47mm low hole type will fit.
I'm at the "discovery" this sounds like a call for water injection cooling. My '71 VW transporter on a daily commute of 80 miles up a 5,000 ft mountain during the hot Summer - never had to pull over. You can do it with gravity feed - but it should really have a vacuum valve - I used a windshield washer pump - that pump will need cooling btw or it will burn out - or get a rated pump. You're right - it will save your engine and make it "water cooled" for about $20.
I have the same issue with boiling the fuel on one of my 49cc 26" mtb with the same stubby intake, I created a ram air pipe that scoops cool air from the front and goes into the air cleaner box, haven't had a hot enough day to test it properly but it feels like the scoop helps with power pick up when you get moving!
Hello MBJ, it’s been a while. Still love watching your stuff, and I’m still building, though my situation has changed pretty drastically, and don’t have as much time to dedicate to it these days… anywho, my friend, I just recently found a part that bikeberry has available called the “CC X-Port exhaust assembly”, now it says it’s for the exhaust, but it matches perfectly to the intake on my bike, and it came with paper gaskets, and so I got a couple of em to experiment with. Unfortunately my bike is not gonna be in any condition to test them for a while… if your carb is overheating, maybe one of those can help, it’s got cooling fins on it, and they’re on sale right now for about $20. Hope this helps buddy!😎👍🏻
Man thanks so much for the fuel solution. I've been going crazy thinking it was an air leak. I dont really know what to measure, What size intake would you call that when ordering a longer one?
LA, the last few kits I've gotten have the ignition rotor upside down so this puts the spark way late in the ignition cycle. Have you encountered this with your motor kits lately? PS thanks for some great video action and testing of the kits.
@@bryduhbikeguy yeah true as we do have type aprovle road regs 75/83 that all ebikes n escooters use for road uses we are same as we are looked on as motorised petrol ebikes but cops will be cops see a petrol motor on a bicycle n its a motorcycle i hope to win in court n get my bike back
I've been really hard on my bt100 and its still going strong but I run a lot of 2 cycle oil like 20:1 just to keep it cool. The only thing that sucks is the lack of a good aftermarket exhaust pipe.
This was my first experience worth bike motor kits!!! I put the battery where you did, but... unlike your use of a good glue, I used duct tape. Lots and lots of duct tape ha but it was nice learning how to ride in the city traffic on this seeing as it's an "automatic," no pedaling necessary for stop and go traffic with the 48t rear sprocket... But I think I destroyed it, it stalled out a few times like yours, and now won't start. Too hot of riding conditions and my error for 40:1 mix + carb boil = super seizure of engine.
Off topic question. What was the max speed on the yd100 in stock form and what's it's current max speed and modifications. Thank you for taking the time to answer my questions and I love your videos. Very helpful. Need some pew pew videos!!! (although I understand demonization)
I wish there were more motorized bicycle engine mod videos where they first do a stock engine test run. Then show step by step engine mods & show/compare how each mod affected engine performance. Like how LA Hover did the exhaust pipe power comparison tests. Or for example, install a reed & window piston. Record the test results, then make a window a little bigger and test results compared to previous, smaller window size. Add a better AM carb, then test it with both window piston sizes 🆚 stock carb, etc...Do reed valve type comparison tests...RSE vs G2 vs OZ reed . So you can see exactly what's going on. Smolik performance had a few good old videos doing dyno testing like this. Like adding expansion pipe to bone stock engine & testing results. Then I guess they wanted to keep what engine mods work best a secret. Most videos are now all over the place. With someone drilling dimples everywhere inside an engine & skull 💀 shaped window piston hole claiming it makes the most power. While others claim a turd 💩 shaped window works better than a skull 😂
Have you ever considered doing a road test with one of the whizzer motorbikes? I've looked through the videos and don't see one. I have an MP5 made in 2005 I also have about seven of the China dolls, but mine are all very old and don't have needle bearing wrist pins or the balancing holes in the crankshaft!
The sideways fins on the head can't be helping cooling at slower speeds. Can you turn the head 90 degrees on this engine? I like the idea of mounting a battery bank for the cellphone.. But this would be great for long range headlight for sure
Can you take a yd100 expansion chamber exhaust cut off the manifold and use it on the phantom 85 v3 since it seems like they still haven’t made one yet I’m thinking about building a fat tire version with a jack shaft shift kit and think it be nice to get the full 2stroke experience lol none the less the phantom 85 is the only reason I’m considering the build considering it can pull away from a dead stop by it’s self
When it stalls out do you try the pull start??sometimes it won't start at a low idle so u have to adjust the idle screw high then lower it so it will idle. I'm only having one problem here and there and sometimes when I hit the throttle on BT80 the bike won't move and just revs and when it ruterns to idle w.e the problem is stops then it runs fine.. great video tho !!
So i installed a longer intake and it seemed to help the boiling fuel but now its drawing fuel into the carb but it wont flow from the petcock and just emptying the fuel line. Im thinking air leak but there's no drips. Fuel line clamp and vented cap are my last hope. Any thoughts or suggestions?
Does anyone know why California motorbikes has their 4 stroke kits listed at like 260-270? That seems pretty steep considering all the variety available at lower prices while not sacrificing or supplementing certain components to make up for any advantages lost in their opting for the alternative. Maybe something that isn't obvious just from the details of the listing or pics provided on their site? Thanks
Hello I'm a long time subscriber I was wondering if you would have an extra electric bike that I could borrow just to see how I like riding them or if gas is the better way to go
14:00 that’s exactly what’s goin, I just dealt with same issue on Jokester and on my buddies bike Mercury. We got a nice head for his but mine is the cdh110 and they don’t make nice heads for it unless I go to RDM or somolik or something n that’s to much. So im working on figuring it out myself somehow.
Those 52mm 2 piece iron sleeve engine kits would have been awesome & probably outsold everyone else if they weren't so defectively made. You could make an air scoop to help cool the cylinder. Aftermarket air scoops worked pretty good on old 2 stroke motorcycles before they went to liquid cooled. Most were just made of plastic that zip tied in place & directed more air flow to blow on cyl. You could make a really nice one by using cardboard & tape to build a mockup & template pieces. Cut your aluminum pieces/ shapes out, then all you need to weld the aluminum pieces together is...Propane torch, new uncontaminated stainless steel wire brush & "alumi-weld" rods from Harbor freight ( not rods for a stick welder) Use some small screws to mount air scoop onto engine. I've had my $25 runleader temperature/ tach/HR meter gauge on for a couple months now & the temp probe loop that goes on the sparkplug is providing accurate temperature numbers. I compared with my heat gun several time & both numbers were always the same. I figured for only $25 the temp readings would be very inaccurate. I screwed up wasting $12 on the common rpm gauge everyone uses. But can use it on my chainsaw or generator. The $25 temp gauge can save a $100 engine & long walk home. Some said their's came broke but might be coz using a no resistor plug or wire . If it came broke u could always get refund/exchange. Gotta be careful not to bend the copper loop too much that goes on the sparkplug. Plus constantly removing sparkplug and/or over torqing it will wear it out since it acts like a copper crush seal washer.
My Bikeberry kit came in a near paper box all 4 head studs were sticking out of th side of the box. Nuts and bolt bags were not sealed properly and I was missing some hardware because of the 8 holes in the side of the "box" theory cnc made chain tensioner is seriously flawed in its design too it make the clutch bucking bar not reach so he clutch can't disengage and its made so poorly that it pins the chain to the entire drive sprocket. They told me to bend or cut it to make it fit but you literally cannot modify the part to make it work. The entire piece is wrong and it was a total waste of 80 bucks. Total ripoff. They literally just sent me the Amazon kit for 100 more dollars... but it has their stickers on it. They will never get good reviews from me and I won't be getting my next few kits from them. I saved their rude and idiotic suggestions to fix their part I paid for too. Really condescending.. and the clown didn't realize that adding in the tensioner changes the clutch clearance and they had no way of fixing it. He told me to cut the bucking bar down..... it literally needs to be the width of the mounting plate LONGER. The lack of support, bad suggestions and call center being in another country makes them next to useless.
@@businessraptor127 man thats ridiculous bud, sorry to hear...Pretty Sh*tty of them to just tell you to cut it down instead of making it right, nevermind the other problems,, ive also had bolts pushed through the cardboard, slightly bent also, its ridiculous the lack of proper shipping,,like i said to LA im always missing pieces,, i got a PK 80 with no carb at all once, no gas line or filter in anothrr kit, stripped head bolts in the case to where 2 bolts wouldn't even tighten,, im very select on who i order through,,, sorry to hear man, ☘️
I just bought a Zeda 80 firestorm for the sole purpose of hooking my 80 lb kayak rolling on a dolly using a diy tow hitch and taking it to the boat ramp about 2 miles away. I haven't seen any videos of someone trying to tow something using these motors. I'd love to see if you have any insight or would be able to test something like this
I have a very different suggestion for a project. Supposedly you can get 2 stroke engines to run diesel, well enough to not need to mess about with them too much. My wonderings have got me thinking about running waste motor oil in one of these two stroke bike engines, I would love to see how they compare power and rangewise to the same engine running it's regular 2 stroke gas. It would definitely be a nice way to putt around town for a fella who has a decent storage of waste motor oil. Any input from anyone here?
Don't know aboutvthe motor but i still have this same bike frame but I think it's a 49cc. It's not in use because it needs anew throttle kit and a back wheel. The wheel was warped. I just got a a 2023 Phat Moto Rover 79 cc for an early birthday gif from my dad I fk LOVE it and will take care of it and not dog it out. I thought the blue one was decent and fast my new bike is amazing, reliable, and exceptional quality and craftsmanship
@@dmoore0079 ok I just installed my brand new bt80 the battery is dead I tried the pull start but nothing happened brand new bt80 engine and hp carburetor
Trying to watch rn but spectrum internet and cable are down atm. And everyone in my area is using their cellular data, making just about everything 1000× slower.
You gotta use more during the first 2 tanks and dont rev up over half throttle and change your rpms frequently. Its called break in period. 16:1 fuel to oil during break in then 32 to 1 after 2 tanks
Cool vid im still going on with my motorised bicycle court case LA hover have you had cops pull you for usen your bikes with cops usen light motorcycle road uses laws 🚴♂️😃👍
Brother I hate how your entire body is higher than the handlebars. I can see your knees above the handlebars and practically every video and that's got to be uncomfortable.
@@Tegridynews you could have a frame built for Shaquille O'Neal with 20 inch tires that would fit him well. Its about the dimensions on the frame itself not the wheels that go in it. If you have a frame changing the wheel size won't suddenly make it fit a rider better, but changing the frame will.
Some chainsaw guys say 50:1 claiming newer oil is so much better than 50yrs ago, so it's OK Others say, show me a 2 stroke that can run on 50:1 for years & I'll show you a 2 stroke that can run with no oil. I run between 40 & 35:1. 1.75 oz per half gallon.
Yeah my neighbor said he was thinking of buying a 2 stroke off of facebook marketplace. I just told him be aware that sometimes people sell their bikes that have issues because they don't know how to fix them. And that it's an expensive hobby in time and money. I mean I'm about to spend 150 on another 79cc r stroke because phatmoto sucks for replacements. It's not that they don't have replacement parts, they just sell their parts way too expensive. Like their engines, almost 200$ for it just because it says phatmoto on it. Ridiculous. I'm getting a predator 79cc. I was going to take the time to save and get the ghost but after a lot of thought, I'd rather be safe. Speed doesn't have to be everything unless you want to go those lengths to make the bike as safe as possible.
Get the ghost... just because you have the speed doesn't mean you have to use it all the time... but you'll actually be safer having that extra speed in your back pocket when needed
There comes a price tipping point on these motorized bicycles to where you'd be better off just buying a decent used scooter or motorcycle. But if you do it right, you can easily build a reliable 45mph top speed 80+mpg bike for $250 in parts. Compared to an expensive ebike build. Motorized Bicycles are way cheaper faster & more or just as reliable as an ebike. An $800 mid drive ebike kit for example, can be ruined by a few storms, heat ,cold or one wreck . Most new people including myself end up wasting money on parts, trying to figure out what combination work the best.
Having to face those manufacturing ramifications is a little annoying, we can purchase a 100$ Amazon china doll kit and most of the time not worry about a fuel tank leaking.
I love the BT 100 motor very reliable. It does get hot sometimes in extreme summer temperatures. The vibration on the motor is very minimal.

When you add oil to wet cluch losing the cover next to the fill hole will let it vent the oil will go right in use motor oil for wet cluch only

Those 52mm 2 piece iron sleeve engine kits would have been awesome & probably outsold everyone else if they weren't so defectively made.
You could make an air scoop to help cool the cylinder. Aftermarket air scoops worked pretty good on old 2 stroke motorcycles before they went to liquid cooled. Most were just made of plastic that zip tied in place & directed more air flow to blow on cyl.
You could make a really nice one by using cardboard & tape to build a mockup & template pieces. Cut your aluminum pieces/ shapes out, then all you need to weld the aluminum pieces together is...Propane torch, new uncontaminated stainless steel wire brush & "alumi-weld" rods from Harbor freight ( not rods for a stick welder) Use some small screws to mount air scoop onto engine.
I've had my $25 runleader temperature/ tach/HR meter gauge on for a couple months now & the temp probe loop that goes on the sparkplug is providing accurate temperature numbers. I compared with my heat gun several time & both numbers were always the same. I figured for only $25 the temp readings would be very inaccurate. I screwed up wasting $12 on the common rpm gauge everyone uses. But can use it on my chainsaw or generator. The $25 temp gauge can save a $100 engine & long walk home. Some said their's came broke but might be coz using a no resistor plug or wire . If it came broke u could always get refund/exchange. Gotta be careful not to bend the copper loop too much that goes on the sparkplug. Plus constantly removing sparkplug and/or over torqing it will wear it out since it acts like a copper crush seal washer.

You gotta use more during the first 2 tanks and dont rev up over half throttle and change your rpms frequently. Its called break in period. 16:1 fuel to oil during break in then 32 to 1 after 2 tanks
isn't your idle too high?
@10:36 curve of memories..
22:45 I can smell the clutch XD
what bike is that ?
I'm buffing for about a 1-2 minutes & getting 5-10 seconds worth of 480p at a time.
When i see bubbles in the fuel line i think the fuel is boiling
What is the battery for anyway?
Its electric start
where do you get your frames?
Those are huffy cranbrooks from walmart
Not all of them,he got one Cranbrook out of a ditch.
😛
My bt 80 (the non eletric version) gets really hot with the stock timming. retarding a bit solves the issue
What'd you call me :P
You could make an air scoop for the cylinder. They worked on old 2 stroke motorcycles before they switched to liquid cooling.
I always recommend you wait for the stripper to do its work. 😎
Do u need a motorcycle license for this
Do NOT connect anything directly to the battery! Use the unused plug in the electrical box.
Thanks for the heads up. That will save me the extra step of wiring in another switch.
Cool vid im still going on with my motorised bicycle court case LA hover have you had cops pull you for usen your bikes with cops usen light motorcycle road uses laws 🚴♂️😃👍
Brother I hate how your entire body is higher than the handlebars. I can see your knees above the handlebars and practically every video and that's got to be uncomfortable.
Hes 6'4 riding a one size fits none bike
@@ShinyUmbreon765 why I'm riding a 29er
@@Tegridynews wheel size has nothing to do with frame size
@@ShinyUmbreon765 I'll never get back on a 26 inch frame to small. And I'm only 5'9
@@Tegridynews you could have a frame built for Shaquille O'Neal with 20 inch tires that would fit him well. Its about the dimensions on the frame itself not the wheels that go in it. If you have a frame changing the wheel size won't suddenly make it fit a rider better, but changing the frame will.
I burn 40:1 that looks like 32 or even lower?
Some chainsaw guys say 50:1 claiming newer oil is so much better than 50yrs ago, so it's OK
Others say, show me a 2 stroke that can run on 50:1 for years & I'll show you a 2 stroke that can run with no oil. I run between 40 & 35:1. 1.75 oz per half gallon.
Yeah my neighbor said he was thinking of buying a 2 stroke off of facebook marketplace. I just told him be aware that sometimes people sell their bikes that have issues because they don't know how to fix them. And that it's an expensive hobby in time and money. I mean I'm about to spend 150 on another 79cc r stroke because phatmoto sucks for replacements. It's not that they don't have replacement parts, they just sell their parts way too expensive. Like their engines, almost 200$ for it just because it says phatmoto on it. Ridiculous. I'm getting a predator 79cc. I was going to take the time to save and get the ghost but after a lot of thought, I'd rather be safe. Speed doesn't have to be everything unless you want to go those lengths to make the bike as safe as possible.
Get the ghost... just because you have the speed doesn't mean you have to use it all the time... but you'll actually be safer having that extra speed in your back pocket when needed
I get better fuel economy on my motorcycle. And it can go highway speeds and still go off-road. Why not have a motorcycle as backup?
There comes a price tipping point on these motorized bicycles to where you'd be better off just buying a decent used scooter or motorcycle. But if you do it right, you can easily build a reliable 45mph top speed 80+mpg bike for $250 in parts. Compared to an expensive ebike build. Motorized Bicycles are way cheaper faster & more or just as reliable as an ebike. An $800 mid drive ebike kit for example, can be ruined by a few storms, heat ,cold or one wreck .
Most new people including myself end up wasting money on parts, trying to figure out what combination work the best.
Lol.the carb too close to the head doesnt help with hot weather .
Use lithium battery
Having to face those manufacturing ramifications is a little annoying, we can purchase a 100$ Amazon china doll kit and most of the time not worry about a fuel tank leaking.
Add a bit of rc nitro fuel ,lol
That set up looks sketchy af, definately not legal in the EU. Any insurance or registration?
Why not just buy a moped or electric bike?
