- Part 4 let’s dig into cheap mods for altered performance. What works and what doesn’t
We are going to modify the 2 stroke zeda firestorm 80 cc on a Nell Lusso
Welcome to ColdStart Garage De-gens and Derelicts!
-We will modify the exhaust to increase performance
-We will remove and replace on the stock head with a high compression head. It's a BBR STAGE 1 head gifted from Dave from coldsmoke
We always have fun. do we gain MPH or Lose MPH? We definitely Gain TORQUE!
leave comments. I read every one and may do what you suggest. have fun guys and be safe out there!
These are the words about the head BIKEBERRY.com
"A Head That Will Increase Horsepower and More
With the added BBR Tuning Billet Aluminium High Compression Cylinder Head you'll get more horsepower and better cooling out of your engine. With this head you'll increase your compression, which in turn will give you more power. More power means more torque and a little added speed, which is perfect for riders who climb hills or face inclines. Its deep heat fins and low profile will allow your engine to cool off faster and stay cooler when you're riding.
Don't be stuck buy part after part you don't need. If you've got some hills to climb or you just want a cooler running engine, the BBR Tuning Stage 1 Bicycle Engine Kit is made for you. Just bolt on the head, install the motor on your favorite bike, fuel it up, and you're ready to ride"
**PART 5 is in the works- some more tests on this so called "high compression" head**

Discussion! Is this BBR HEAD a high compression head as stated on bikeberry? Or is it gimmick? Leave a comment about your guys experiences!
If the combustion chamber volume is smaller, then yes it has a "higher compression!" How much of an increase depends on the size of the new volume vs the old volume!
Am I right with my assumptions? I have no idea. I know enough to get myself into trouble. My next set of test will either weld my crank to my bearings or get me my mph in my next video! That’s what she said 🤣
Easier muffler mod remove baffle cut off long extension tube even w the cap an drill 5/16 hole opposite of exit stub . Not much louder but much more power .
I can tell you watch a lot of vice grip lol nice video
Allegedly 🤣 maybe when this video was built. Not so much these days.
Sir you should check the sparkaltors gap before put fuel into the fuel make it happener
Change for a high performance cdi that really help
use a bbr tuning copper headgasket they are 7$ on amazon
Get a f2 thust pipe . It’s one on the beat mufflers out there in my opinion the sounds are good
Good stuff buddy ! Tuning in
The open pipe does give you a few more miles per hour
Great video man 👌 love your attitude and out look
Thanks for the view and the comment. I’m glad you enjoy the movie
@@ColdStartGarage I got all kinds of porting and crap talking vids start at oldest first if you want to avoid the crap talking
Oh man the kroil! High dolla spray my man!
“Free” left in my tool box when I left my last job in aviation. 🤣 the guy checking my tool box did not care. It has a delicious aroma
Nice bike guide to build
Stay tuned more videos will be captured as soon as the snow melts!
With higher compression, you can raise the exhaust port and still have more low-end than stock while getting more top end power. The pressure differential is greater with higher compression and it does most of its work earlier in the stroke. The mixture burns faster, so retarding the spark and running higher octane is needed. I shaved my head, 148psi, ran 91 and my spark plug began to glow after about a minute of high rpm riding. I didn't retard the timing, but raised the exhaust 2.5 mm, and widened it 4 mm. The bike was quick but blew up 50 miles later.
That’s some great info! Thanks for that comment
How fast was it going with all those mods? Before it blew?
35-36 if I remember correctly. The exhaust mod gave me faster acceleration but I lost top end. And 4 stroking reduces the top end as well
@@chriskosza7383 I was able to go 55-58 on a slight downhill with a 32 tooth while tucked. With a 36, it would get to 49-51 and could cruise at 44-45 no problem. It wasn't fun below 15. I had to pedal a bit past 10-15. I think it made peak power around 7,500rpm.
@@marthamryglod291 do you have a video showing exactly what you did to your motor to achieve that power. I have the bbr stage 4 and idk what's up with it on the stock 44t it went around 25mph and with a 32t it only goes between 30-33 maybe!?
Very neat, subbed!
It still will run u will pick up low end power but lose high end .I have a few bikes I keep tje cap off for my trail bikes
My experiment proved your comment! I had a feeling it would do that before hand. I want a pipe with an expansion chamber anyhow.
We will put it back into the red soonish! 🏁🏁🏁🏁
Such fun lil death traps. Offset magneto key when you go hi compression. Properly set up exhaust will 4 stroke until you hit the throttle. Amazing what these pos's can teach oneself.
If u know what you're doing, u can modify the magnet in order to make the ignition timing adjustable and dial an extra hp or two out of these engines ! That's a huge gain considering they come from the factory with 2 hp at the most...
I’ll keep this in mind. Sorry for the late response 🤣
@@ColdStartGarage what he meant was...if your hands aren't jiggling like a sawsall, you take a square needle file and move the magnet keyway to the left.
Thus retarding your stock crap timing.
Ultimate coolness is Jaguars adjustable slope ignition box. The suicycle years...
To reduce four strokeing try raising and widening the exhaust port
In part 3 we polished the edges out of it. Thank you for your insight. The polish isn’t much for widening .
@@ColdStartGarage polishing is a good thing due to manufacturing quality but exhaust duration and port area are just too small for those cylinders to run properly.
Try widening 1 mm on each side and raising by 2 mm from stock timing
to get a few miles per hour faster you can ramp piston at exhaust port, 45 degree angle 1 mm down and 1 mm in
@@ColdStartGarage It cost 212 American dollars to nikasil these cylinders
I'm having pretty significant 4stroking happening. I have the bbr stage 4 racing kit on my bike with the big compression head and I gotta say I'm a little disappointed. It only goes about 30mph. I've ordered pk80 kits that always get 38-42mph stock?? What do I do!
Please HELP ME..what the number spark plugs !??
NGK B5HS for a standard engine or a cooler B6HS if you have a hotter setup such as a high compression head. With the NGK brand, the higher the code the cooler the plug runs.
Here are some plugs to try on these 'China girl' 2 stroke bicycle engines:
NGK B6HS & B5HS
Champion L86C
Champion CJ7Y low profile
Denso IWF22
Autolite 425
Bosch W9EO
If your talking about the round black head in your videos cover image it's not high compression and it's not made for a 80cc even though Ebay or amazon add probably told you it was lol! they are cut for a 50cc kit and normally just widen the piston seat ridge to fit 80cc kits 47mm piston. That is why it's $13 with free shipping!
It’s free. And she scoots pretty good. That was painted by Dave from coldsmoke. Bike berry
Pretty sure it’s a bbr head on my firestorm. I’ll dig more info and relay it correctly to you. DM me on my Instagram. Any info you have I’d love to here it . The link is available on my channel. Hope like the video once it goes live
That's the cylinder head that came on my 66/80cc BBR stage 1 & stage 2 kits.
Are there better heads with bigger fins available? Absolutely.
Does the free replacement head featured in this video have a CNC machined modern combustion chamber and does it make more compression & performance?
You'll have to wait and see but I'm betting the head will give positive results.
🏁
@@ColdSmokes Fact your even saying bbr stage1 in title like means anything funny all in it's self lol funny enough BBR just logo slapped on china made random parts by company has one of the worst parts reputations in motorized bicycle community lol! Same crap parts you find on amazon half price. Just saying been cutting custom cnc heads for people for about 5 years now for motorized bicycle builds. must have 500 heads cut and 300 cases now from everything 50cc to 90cc minarelis on facebook now. wouldn't consider a 9cc head to be high compression to start with but! To each his own! Good luck with it! No ill intentions! hope works out well!
Hello friend, nice video. Very funny beginning. A strike with the Bud Light cans! 😀 hehe.
You should have just left the end out of the muffler.. Why bother cutting off the nipple? You only gained just a tiny amount more hole diameter size.. Just take the whole entire end out.. Then in the future you still have it in one piece if you want to put it back in. You know, like if you decide to sell the bike. It will be complete, not all cut up.
I’m just trying things out so you guys don’t have too.
they make a thinner head gasket than the stock alum, about 1/2 thickness brass on amazoom five for 7$
I will be looking into this. Thank you
Bro dnr cut it just take it off and keep It to the side.two stroke need the back compressions to push the Piston back down
Thanks for the comment. I’m doing experiments for every one. I have some upgrades planned for after the winter.. by plans means I don’t have anything in the works yet due to winter and lack of funds… damn it 🤣
Weld that piston to the cylinder! YOUUUUUUU WONT!
If I’m wrong with my theory… everything is gonna weld its self by magic. And it will prolly be the longest walk of shame I’ve ever had to walk… knowing my luck
Gonna be SENT
Me head performence the spark plugs is small..what the diférence normal size spark plugs vs small spark plugs ..??
Sparkplugs are rated in temperature ranges, two different sized plugs with the same temp rating will perform exactly the same. people use a small sparkplug due to a lack of space in terms of engine fitment, that is all. For example - going from a NGK B5HS down to a cooler B6HS is a good idea when you fit a high compression head due to the increased operating temperature associated with increasing the compression ratio.
NGK B8HVX
It's a POS
Don't bother trying to port correct this with that head,
Best performance gains on the super cheap are exhaust and carb tuning
Lessons were learned. And fun has been had by all.
Your head performence what the number spark plugs !?? Please je ne suis pas capable de trouvé le numéro de bougie..je sais que sais 9.7mm/9.5mm/69.5 dimension

Damn bud you put the absolute best oil you could find in it but add it in with some 87 octane when all these should be ran on 93 octane. Just saying that mite help a little.
I switched over to the higher octane. Beginning of this summer. Thanks for the comment!
Thats you told
You have to run high test in these or womp fuck boom
I don’t understand what you mean.
@@ColdStartGarage 91 octane
Ah now I’m following🤣 it’s the am here and no coffee yet. Ya seeing that it’s up toward 145 psi I was thinking the same thing. Thank you!
You sound and act like Derrick,you guys cousin's?
You are not the first person to say that. But he is far more successful and way more talented. I might even dare say he is better looking 🤣Some of his sayings slip through. the more I film the easier it is just to be myself. But damn some of his vocabulary just been adopted.
Is that an AVE sticker on your bike
I do follow AVE. But one is a spitfire logo. A skateboard wheel logo. And the YouLose… I’m unsure who made that! But that guy up north is a funny dude!
My son bought a whole sticker pack. And them two two made the cut ****edited due to grammar issues***
@@ColdStartGarage Take them off I will sub and include your channel in my videos Me and Mr. AVE have a History just saying I like your content can't stand him just saying.
I suded anyhow like your content I will post your channel on my next video I post a lot of really GOOD channels shout outs.... ride safe brother.
It took me 6 months to figure out what you were talking about🤣 the fire sticker is spitfire company they make skateboard wheels. It is not Ave logo.
My bad keep up the good work.👍🚲👍
Where’s the burn out
I have plans for the winter. But I have to save on the wheel assembly until I can throw some money at it
But I do have a burnout in part 2. Gotta break in a brand new motor some how
Are you still using the wife's toothbrush to clean things?.. Lol, you the one who gonna be kissing her..hehe
🤣
That particular style of so-called 'high compression' head is rubbish - it may raise the compression ratio providing the squish band is reasonable but they are utterly crap at cooling the engine. To draw heat away from the cylinder and the rest of the engine you'd need mass in the head to act as a heat sink with plenty of fins to allow air flow to release the heat.... Now just look at that bad excuse for a head you have there ! I wouldn't have even wasted my time swapping it on ! If you're going to upgrade the head to raise the compression as well as to aid cooling, then go with one of those cnc billet type that's got plenty of body ! Don't forget to change your sparkplug as it's now gonna run hotter due to the increased compression.
Go check out my part 3 if you have a minute 🤣. But I’m aware of the fallacies of this particular unit. I’m in the middle of marking a new video on exactly what you are talking about.
I’m just a guy trying to film some stuff and have some fun doing it. And you guys that leave comments. I learn a ton from youse.
Thank you for the view and comment. It does help out a ton
That head is not as bad as you think
I do have some good things to say about it. “Some”
that head is avrry bad for that jug it will make it over headt an will not do much for speed u dont no what yr doing stop sir if u whant speek get a muffler
I know what I’m doing🤣kinda! I did an experiment with a gifted head and found out the hard way that I need to try something else. Thanks for the view and comment. Stay tuned fun will be had by all
