i had 140cc yx engine 26mm carb 10+12" wheels that ran 108kmh(67mph) under me 90kg driver, sprockets were 17-32 if i remember correctly, using right sized exhaust pipe is also very important, if u have original pipe u could use little bit bigger,

Wicked man if you also went up in carb size you’d pick up afew more mph top speed not sure about getting to 70mph but I’m sure it’s achievable with head work also highly recommend using a rim lock will save you tubes

@@Jazsft mines just a factory 22mm mikuni carb that’s comes with the engine. I’ve never had issues with them but it’s gotta be restricting some power if others are running much bigger sizes. I’ll look into maybe a 28mm and see what it’s all about.

@Jack Song I think you’d be surprised what a tb v2 head and a pe28 would do for a 140 and with a z40 being a slightly larger cam I believe it would give you better top end over a tb300

My seal behind that gear leaked and busted how can I find one? Is it the same as the yz or yx or something? Help lol it's my first bike. It's a 2022 140 swapped baodao BD125-11-GT, and found most of the parts I'll eventually get but also when I take the kickstart cover off it can slide back and forth and touch the case is that normal? I'm dreading taking the motor out and ripping it apart but it's fun upgrading and fixing it. It runs smooth and shifts okay could be a little better, I plan on doing the stator, clutch, clutch cable, throttle cable at the handlebar, exhaust, maybe touch the valves, big bore kit, so if I upgraded to the big bore and made it a 190 would the 26mm carb still be okay? I rode it back with every bolt loose, taped wires, looked stolen but the vin is clean so IDC old plug wire melted itself, it will be nice I got spark plug coil, new plug, oil change again, 26mm nibbi carb, ignition with key and did the wires again, just need a seat key then I'll have 3 including the bolt in tank lock I got, might wrap it or do some plastic and body work got gold fairing bolts and a custom plate and engine mounts coming can't wait

How do you tighten the rear sprocket bolts it has that plate thing around the screw heads
@slavsquad2 жыл бұрын
You gotta bend those flush with the sprocket. Then bend then back once you tighten the bolt back up when putting new one on. That’s there to keep the bolt from coming loose

nice bike man, had a Lifan 125 back when I was a lil teenager and didn't know how to take care of stuff hahaha. Now I'd like to get back into pits and I'm thinking YX 140 this time around. Just had one quick question, where'd you get those plastics for it and what other bikes do they fit (for cross reference)? Anyways, thanks, keep it up.
@slavsquad2 жыл бұрын
Haha I was the same. Now I’ve been taking care of my bikes and making them to My taste. The plastics are just regular white plastics off eBay and I throw in my own taste in stickers from past parts I purchased

They fit a lot of pit bikes. You just have to look at the plastics shape. Most bikes that come factory 110cc-125cc have that style plastics. Then 150cc -170cc have a klx 110 style plastics.

If you want top speed to increase go 17 front 35 rear. Bigger front sprocket and smaller rear. It will reduce your torque by a little so your compromising the low end a bit but not to much
