Tillotson 225cc Big Valve Build | 9,000 RPM, 25HP Billet Maniac!
Vložit
- čas přidán 31. 05. 2022
- The Tillotson 225cc high performance go kart or mini bike engine is already a powerful small engine, but in today's Honda clone build episode of CarsandCameras, we're installing billet parts and doing a ton of DIY head work to the Tillotson 225cc engine to take it from 15 horsepower stock to 25 horsepower. In fact, on Go Power Sports dyno, this engine makes over 30 horsepower running on methanol fuel. The parts list is long and very impressive- this engine build represents the cutting edge of widely available small engine performance parts. Thanks for Watching!

I realized we built a big valve head, but we didn't share the valve specs! Stock is 27mm intake, 25mm exhaust, and we upgraded to stainless steel 28.5mm intake, and 25mm exhaust. Doesn't sound like much, but between the better design, larger intake valve, big cam, 1.3 ratio rockers, heavier valve springs, and lighter components, the valve train is WAY better than even a stock 225.
Y not 32 28mm valve head with a 308 cam
Thanks for the update.
I just got an EC 228r wonder how it compares.
The exhaust port on my DMP 70cc Puch E50, is 25mm.
Still waiting for Tilloston to make a 225 with a dohc head.
The Ikerometer needs to be a T-shirt. At a previous job we had to observe ASTM testing methods. My boss Jerry would fudge the numbers and thus implemented JSTM testing. It all works.
Eye-crometer
@@aaron7520 it's a play on Ike's name!
ike-rometer!
@@leviwilder1205 woooosh....
The eyecrometer has much closer tolerences than the Ikecrometer ever will do to aging optic faculties and the "Aw hell send it, it'll be fine" factor.
Big companies would like to know your bosses location
You know it's a serious CarsandCameras build when the "click" is real. Awesome build, can't wait to see do a hotlap.
I gotta admit that when Charles first got added to the team I thought it was gonna mess with the dynamic of your videos but I was dead wrong and think he is a great addition and brings a lot to the channel.
I thought Charles would add to the technical aspect of the channel and his experience is proving that out.
Charles in charge big time
You guys should go on more adventures, you always remind me of the original Top Gear cast, and their adventures were truely legendary!
Thanks for all the great content
I'd love to see them do 3 hot wheel builds and take them on a adventure with Grind Hard Rather B Welding etc etc. That would be EPIC 🔥
Great idea Spyder !!!!
I’ve been subscribed since freshman year of high school, maybe earlier. I’m 23 now and still enjoy every video like when I was younger. Always enjoy seeing a cars and camera video pop up! Especially lately, lots of cool projects going on
Card and Cameras 😆🤣 sorry bro but that was funny 🤣 We all screw up some times lol ✌️
It would be nice to see more use of the already existing builds. It seems like it's just one project after another. It would be cool to see old builds revamped with your current skills and resources
I agree. There are lots of builds that need finishing/tuning. Most of our energy has gone into building out the new shop (going on a month now), so our regular uploads have been less episodic. We're planning on getting back to finishing other builds soon. Thanks for the comment.
@@CarsandCameras looking forward to it !
Ike, so much knowledge to give and so good at presenting it. Charles seems to really know his stuff, too, with the added levity. And John brings it all together. Great channel all around, fellas. I always look forward to another episode. Looking forward to some car build stuff. I get some of that from Ike's channel. Keep them coming!
Putting the lapping compound on the flywheel and crank, is known as, "lapping them together."
This is done on gears, slides on 1911 model pistols.
We did it a lot when building inspection gages in order to obtain very close fitting parts.
Hand fitting. The lapping seems to add to longevity as well if fitted areas are kept clean and lubed properly.
Nice thing with the methanol is it will definitely run cooler. More Power is a plus as well. Cooler And More Power - Mo Mo Betta!
I just enjoy watching Isaac and Charles doing all the work. They work so well together.
Thank you for the 2nd click, i was taught to always do 2 clicks when using a torque wrench; many times i do it and the nut moves just a little bit more before clicking the 2nd time
Using the compound is to ensure a good tapered fit when you decide to remove the timing key completely. The timing key is just that, a timing key. Its not what holds the flywheel in place, its used to line up timing. Myself as well as many others remove these keys completely when advancing timing. The taper on the crank is what holds the flywheel in place. We just use the compound as seen here to make that tapered fit even stronger since we remove the key. FYI, advancing a quarter width of the key is around 7 degrees advanced.
You can use an offset key in the key way to advance the timing, two fuel pumps, methanol fuel, bore the block 0.030 over.
Does the offset key just change the ignition timing, or the cam timing?
@@jeffrykopis5468 ignition timing
been waiting for this all week work is a pain in the ass and watching y'all makes the week a little bit better
I always heard you gap exaust a little more than intake because exhaust valve gets hotter and metal expands more and the intake gets cooled off by fresh air fuel
I would love to see you guys do a video on how not to build an engine with the worst parts you can find and the worst technique, maybe a competition to see who can fry an engine first
Rtv wars coming I can see it.
The easiest way to destroy a small engine like this is to turn it into a race engine but cheap out by using the stock cast connecting rod, which will be thrown right through the side of the block at sustained high revs.
Man this is my favorite kind of video from you guys!!! You guys have no idea how much y’all have inspired me. Just did my first big build on a predator 224, tires out pretty nice if I do say so myself. Thank you guys!! Y’all are awesome!!!
Hey cars and cameras love the content keep up the great work
This engine is a monster! What should we put it on first?
The Ruckus!
the yard dart!!
Ruckus!
Put it on the mtd minibike
Just for kicks, the smallest real car in the fleet?
Nice engine! Looking forward to the first rip on whatever you throw it on.
Man that thing sounds wicked! Can’t wait to see that on something and going, around the course or track or whatever! Get er did boys, get er did!!!
That is one good looking motor you guys built ! I think it’s going to be a real beast can’t wait to see what you stick it in ,and what it will do ! great video guys and great work!👍🏼🤩💪🏼
Love the videos man can't wait for more bangers
Incredible build guys,, can’t wait to see the go fast goodies for the 459
Ike. I really enjoy it when you guys build these engines. You Ike have a great way of explaining why and how these things are done thanks guys.
You're right about not lapping valves. There needs to be a 1 degree difference between valve head and seat. This difference goes away at temperature because the valve head gets way hotter than the seat, therefore different expansion. You really need a PCV to keep the crankcase under vacuum. This reduces oil leaks and helps keep the crank motion from pushing all the oil to the sides of the case.
just to think that I've been watching from your first video y'all have come so far from a garage to your own is just insane congrats .Jacob
Man I'm not getting notifications. This video says 13 hours ago, and no notification on my end found it while browsing. Long-time subscriber check all my bells and whistles, what's up. Peace out guys keep on rolling🇺🇲🇺🇲
I’m not getting notifications either . Wonder if CZcams is messin with the boys .
roller rockers on a small engine I love it!
Great vlog Guys! Keep them coming!
I am so ready for that next video ! I suddenly jumped into gokarts recently due to being gifted a old Manco White Fox 2 451-391 that I am replacing the B&S 5hp for a 212 predator and new tires, replacing a bent tie rod end on the steering, and a new seat and she should be ready to rip!
Great educational video. Thanks guys.
great stuff guys thanks
Love you guys. im a kart mechanic at a kart rental place were now runnin tillys because of you guys and gopowersports. Tip for takin the valve cover baffle out... Hit it with an air gun 100psi through the hose to the air box it pops right out. And flys about 30 feet lol
Awesome!!!!
Great video glad to see another engine build 👍 .
It is amazing how far the technology has gone since the mid-eighties when we ran modified Briggs flatheads. We started by boring the block .100" and popping the valve seats out for the big Horstman setup. The crank was the stock 5hp Briggs that was balanced between two electromagnets from security doors from an office that was being renovated. Horstman ground their cams from welded up stock blanks so we had to work with a smaller base circle. I would take stock lifters and lengthen them with weld and hand grinding to make it work. The piston and rod were from Horstman, the intake port was actually ground through at the bend and built back up with JB weld and re-ground. The head was "decked" with sandpaper on a broken piece of headstone donated by the local monument co. The carburetor was a Tillotson with a secondary pump powered by the crankcase pulse. At Flemington, I was able to turn 9400rpm. I have to look, I may still have that engine in the shed.
A guy named Horstman traded me a 2hp Briggs engine for a DellOrto racing carb. I put it on a 4.5 horse Tecumseh and ran methanol Heet (available at the time over 50 years ago) along with Wynn's nitro additive. I straightened the "S" intake manifold also. That Kat mini bike would stretch your arms out and held up to the fuel too!
Great video guys
I love the billet parts and thT awesome orange/red lines a dedicated subscriber sent you 😁
Awesome 👍😎
hello great job on all your builds , my name is david and i raced karts for many YEARS dureing the Days of the FLATHEAD , i ran in the Open modifyed class on a 1/4 mile Dirt/clay high banked track and both of you guys know how much RAW fun that can be FUN ! i allways loved them small engines thats why i enjoy your show ANYWAY the kart racers have went to the OHV engines now my day was them briggs opens with the stroker cranks , larger valves alot of porting we even had our own cam grinder ! so we tryed everything our best carbs were the tilltsons alky carbs like the HL-355 souping up the engines was alot of fun and a heck of alot of fun too we had a kind of team with a main engine man who did all the cam profiles and the machine work and fixjures for that work there was him and his son and i did the driveing we could not have done as well as we did without the main engine guy his name was "ThePossom" yes we are rednecks alabama yup you'all know rednecks run dirt ha ha you all keep putting out the good content DBN
I’m gonna be honest as soon as I clicked on the CZcams app your video popped up and all I saw was big cam and without hesitation I clicked on it lol
Looks like a beast 💨
Fn beautiful! Such a monster
Looking forward to see this installed on the cart.
Looks badass 😎!!
Y'all are the best, so informative! Would love to see this motor on a Mini Bike!!
i love these builds do more plz love the vids.
Needed this
I really wish people would take note of builds like this and put these engines in Power Wheels vehicles so their kids could zip around.
I'd love to see you guys collaborate with the "Robot Cantina" channel! Ya'll would like his Predator powered Honda Insight project.
Great build fellas.
Little trick I use when installing retainers and keepers with that style of tool is to put everything on top of the stem then lay a ziplok bag over everything. After that use the tool to compress the spring. The bag will keep everything in place
Can't wait to see that one run
Wow nice setup the engine I like that my friend
You guys should look into check valves and exhaust scavenging for PCV.. The exhaust gasses vacuum out the crank case gasses and it's good for more horsepower. 5-8 hp on a 355 oval track motor.
Seen red beard build a ghost great little engine keep up the content 👍
I just test fired a Predator Ghost tonight and had the throttle do that, kinda figured it would so I put the front wheel up against a wall before pulling the cord. The 7/8 throttle kits need a thread or two cut off the cable sheath or the pressed on end pulled off and about 1/8 - 3/16 of the sheath cut back or the internal cable is too short for the Mikuni, Chikuni and WalBro carbs. Pain in the ass. Finishing up a 236 Tillotson with a Billet head, need to cut the pushrods to length and check the rocker arm sweep. Might post a Video on my little channel. Love you guys 👍🏼
I usually freeze my parts overnight if possible. That way I know they’re cold as they can be but good video regardless.
I’m early yay I love you videos you guys inspired me to buy a go kart and work on it 😃 have a nice day and I have bin sub for 2 years now
These build are what I like to see
im just looking forward to seeing what the boys put this monster in, maybe the scooter/moped from last week,
You guys have a great sponsor. They seam pretty good to y’all
When checking the push rod length, you can also color the tip of the valves with a sharpie and instal the rockers try then rotate the engine a few times and when you take them off you can see where the rockers are sitting.
Sharpie the valve tips will leave a nice whiteness mark for pushrod length. Also most important part of new valve spring is seating the locks. Always smack the valves with a soft mallet to seat the locks. You guys need to build a engine run stand by now… All these engines built over the years… take a spare engine plate weld it to some steel with rubber pad feet and boom. No more chasing them across the concrete on plywood lol
Looking forward to the shootout!
The last time you filmed you guys changing vowel guide rods eyebrods and vowel guides was in John's father's Garage and I remember it was quite a loud ordeal. Have an excellent day
I like Ike he seems to be the only one on cars cameras that knows how to wrench on engines the other guys a dork but shout out to u Ike keep wrenching why the other stays your cheerleader 😆
The motor should be a power house 🏠 for sure 😊👌 cool stuff allsome work guys from cruzermans inventions 😁🎉👍
You guys need to build a jig onto a workbench for doing cylinder heads. I have one with a piece of stainless with a big hole drilled in the center for the tool to go up through. Then a small wooden catch basket right on the front edge to put all the small pieces valves guides keepers etc. Saves me tons of time and headache and only took me a couple hours to build
I love the longer videos especially engine builds
Love the engine rebuilt that’s awesome you go cars in camera
Motor looks bad ass👍❤️
For those breather hoses look at using a vent to atmosphere baffled catch can. The more the crankcase can breath freely the better and it will also lower oil temps.
CHAWWW BRUH.... I got my pop-sickle and I'm ready to watch this HOT video and hopefully get inspired.
It's been a lot of fun watching y'all progress over the last few years to, at times, almost seeming like you actually know what you're talking about (teasing). I know I.C.E. motor's aren't going anywhere anytime soon, but I wonder how long until you guys do a project with an electric power train?
9k rpm’s 😳holy molly sweet👍😎🤙
Methanol you will want bigger jets in the carb and more spark timing advancement. Which on the old Briggs engines was achieved with offset flywheel keys
29:58 - *crushes scouter* "IT'S OVER 9000¡!" 😠
🤣🤣
Thanks Uncle Issac!
also you need to have the appropriate crush on main bearings so they dont spin, .003-.005 roughly definitely do your home work tho. on polishing the intake you want a desired 800 lubricated grit finish for correct atomization of stoichiometric ratio. i learned the hard way when i was a kid. you guys are doing great! keep it up.
Ike is your master small engine assembler!.
Can’t wait to see what you guys put this in. I’m pretty sure you guys know where there’s an airport handy. Maybe instead of pump gas, you should use some 100 octane aviation fuel!
Damn 1 mill subs?? I remember watching this channel when I was in middle school around 2013 give or take an you guys had like 20k subs and I thought that was a lot
Awesome.God bless everyone.
John , I see that your Dishwasher is around the corner from your sink . I used to deliver and install D/W 's . The Water needs to be real hot to do a good Job , So I recommend that you fill and drain it Several times to get actual Hot water to enter the D/W , The Energy requirements eliminated the Long duration internal water heaters long ago , until the water is Steaming , the machine will only do a sub standard job . Proof to me was my friend in an apartment over the massive water heater , doing a great job with the cheapest model Hotpoint , Mine being a high end Kitchen aid and I needing to run water hot , at the sink and then the fill drain trick .
Love the ducarti and all the builds, do another motorcycle engine on a gocart like a Honda 1200 that would be awesome
If you colour the top of the valve stems with a marker pen before you put any lube on the rockers, you can install the rockers and turn the engine over a few revolutions. The roller should wear off the pen and give you a very clear indication of the positioning on the valve stem.
I love Isaac's petrol I/V. bottle
Instead of running any kind of zinc additive...could always run rotella 15w40 or 5w40 diesel oil. It's loaded with high zinc
If you want 'free' horsepower, use a one way valve in the exhaust runner, attaching a hose from the valve cover and crankcase o the exhaust one way valve. The exhaust flo vacuums crankcase and valve cover pressure. Otherwise you're only pressurizing from top to bottom over and over. Idea is to rid any pressure below the piston which will allow the rings to return on exhaust stroke without pressure on the cylinder wall. A set of Dykes rings would increase power and rid drag on the cylinder wall when not under compression.
Old is new again. I always run the scavenging hoses from the valve covers to the exhaust in order to decrease bottom end pressures. Free ponies from that point forward.
I'm no mechanic by any stretch of the imagination, but I was wondering why you would pump pressure back and forth between valve cover and crank case, but then add a vent in line.
Great show gyes ✌
Methanol makes torque boys you will like it!!
You know if you want to check a valve seat all you need is some DyeChem or a sharpie. Just color over the area in question and push the valve into it. Rotate it a little and see where it removed the sharpie or other marking fluid. Its easy enough to clean off with a bit of isopropyl alcohol.
Also deck the block. We used to make so much compression we had to use a car starter with a belt to crank them
Another great video guys. This Old Man really loves your videos. Keep them coming. 🛵🧔💝💝💝
You want to keep velocity up when porting . Matching the transitions between carb to head and boot or insulator between them help allot also
For case clearencing some guys cut a old side cover leaving a few bolts and the guide pin holes
You dudes are the cats pajamas!🐭
Lol shade tree mechanicery in action i love it .
Okay carsandcameras on the valve lapping compound on the flywheel your half way right if your buying a aftermarket flywheel it could be off a little bit and the tappers not match because sometimes they use a different machine in the factorys or somthing i dont know but what i do know that you do that only because not all flywheels arent perfect for each motor and it could cause unstable movement and destroy your internals or break your flywheel off
I was waiting for Isaac to say "It'll Be Fine"....
