6x what it made stock. No porting, no flow matching the adaptor plate etc.

@@SafetyUggs I already ordered it, i have 65% balanced crank, im gonna flow match the cases to adapter and adapter to cylinder, i will port the intake and polish exhaust, i have 21mm dellorto carb, i will make custom intake manifold drilled out to 21mm also but i have bad pipe, it is MX65 clone with a silencer. I wonder how much power will it make

You mean the info I included in this video? or something else?

Sorry I was distracted when you talked about it my bad.

@@Paul_Gale i didn't port match the transfers and I'm sure there a bit of power that could be had there when I do. The high flow mod is straight through the carb, both sides

Thanks 👍

Yeah we can do another run of those, I'll put that listing back up next week

@@SafetyUggs ok great I'll look for it then 😊

Ignition control could help there, I've noticed in that VM18 test that was running lean really improved that dip but hurt power everywhere else. Detuning the pipe would help too and I think I'll give that a try next. It could also be the stock porting numbers make the engine much more effecient at that dip, sucking in a lot more fuel. If I moved the pipe's peak to that dip I think we'd see some pretty big HP numbers, if that theory is correct

​@@Jarrod_D 🤔💬👽👍

Stock exhaust was a flat 1hp, the peak when the pipe hits is ~6hp. The dyno may be reading high or low but it's more just a tool to compare mods and tuning

I really appreciate how much info you share, and time and effort into your videos, you're a true diy enthusiast.

Lmk if you do and I will check it out

Bofang power 💪 and math 😊

This is who you want to ask about the perpex covers 😳

​@@Jarrod_D designed for the porting... 66/80cc lot of work went into that beyond a box stock kit

It's a shame we can't legally ride these on the road over here :-(

@@SafetyUggs Same in Canada, but they haven't bothered me yet. ( knock on wood) I stay under 20 mph on the city streets . that's the E-bike limit. { Riding motorized bikes on the sidewalk or street is illegal in Canada.)

Thanks :-)

@@SafetyUggs most welcome sir

youtube is really sensitive with links in the comments but if you go to aliexpress and search for "Performence Cylinder Kit 2V 80 for Bicycle Engine F80 47MM 80CC" you'll find it. It's USD$29 plus shipping which is pretty good value for what you get

@@SafetyUggs Thanks. More for curiosity, I'll check it out. Keep up the good work ! My 80cc build hit some major roadblocks with the frame wheel combo so I ended up buying a 1500W ebike

That combo should really pull once its all set up! The 090 carb will need a crankcase vacuum signal to work correctly. You could drill and tap behind the reed block and grab the signal from there. As for tuning it, start rich. I believe for a saw you'd start rich, hold the throttle wide open and adjust the H mix for the highest RPM, then back it off to the rich side so it drops a few hundred RPM. Confirm with a new plug, do a 30 second wide open throttle ride then cut the engine, don't let it idle, pull over, pull the plug and check the color. There should be a heap of charts on google on what a 2t plug should look like when its running right. Rich is always safe even if you loose some performance.

@@SafetyUggs thanks will do. I have a brass tube fixed to the crank case where the transfer bulge sits and one on the side of the carb.connected with 5mm fuel line. It runs good at 48kmh and tops out at 56kmh. Will report back when the new cylinder is installed.

@@johankemp3809 Sounds like you have it all sorted. You should be seeing at least 60kph on that new cylinder, I wouldn't be surprised if you get it closer to 70kph with a little work

Oh if you have the CDH pipe with the huge stinger, it needs a silencer or other restriction for the pipe to actually work as a pipe. There was a pretty big increase in power once adding a silencer to that pipe, without it it was barely better than a stock pipe with the cap removed

I think i have the smaller one. I use the original chrome exhaust cut before the bend and jammed inside The cdh. I removed the whole tube from the cap and drilled 2 extra holes. Without this the bike is to loud.

It's an old chassis Dyno from a workshop that closed in my town. I fitted new electronics and it's good as new.

Bofeng with a drilled out venturi - should be a video of it in this channel or there's dyno sheets with before and after in the forum

@@SafetyUggs ive got a vm18 ln mine

From what i'm told the jackshaft kits aren't good for big power, the bicycle chain will tear apart

@@SafetyUggs fair that. i may have just wanted to see the torque carve per gear shift but that's a lot of money for very little content
