Congrats...Does it have a title for street use?
tmas
yep

Did you buy it in northern CA?
yep

The bike wouldn't idle and was hard to start. I cleaned the jets and it still runs horrible
I just ordered a Klx 110 carb. I'm having a hard time figuring out how to tune the carb on this. The tank has to be off in order to get to the carb so adjusting the air fuel screw while running the engine is nearly impossible. I think I need to make some kind of remote fuel tank system.

What's the sprocket setup on it?
This bike has 10" tires right?
Can you let us know the top speed you are getting on it?
What ya pay for it?

Are you 100% sure you got the pilot jet completely clean?
Yeah, I used a bristle from a wire brush to clear out the main and pilot then I blew it out with 140psi

I live in Pleasanton, if you are near by you can bring it over and I'll help you get it running.
Thanks! hopefully i can get it running better temporarily until the new carb comes in

It's got ten inch wheels and stock gearing. I've had it up to 55mph! I paid $700 for it.



I swapped out the stock carburetor temporarily with a molkt 26mm with stock jetting with the needle dropped one clip from the top.

I removed the EGR and plugged up the EGR port on the head. Theres a catalytic converter in the head pipe that is restricting my top speed, the diameter of the exhaust tip is also restricting the engine rpms.

I know what a PIA this is. My solution is to replace the fuel hoses and get another 3 plus inches of hose. You take the back gas tank bolt out of the tank and swing it off to the side. You can always rest the tank on something or have someone hold it while you work on the carb.

thanks, I'd like to know this info or at least the gearing setup.
$700 was a good deal I'd say.

No problem on the tooth count, whenever u have time.
Mine has a cat also but I bought a mini gunz exhaust and it now goes about 5-10mph faster on the top end.
The stock exhaust is very restrictive on the top end.
I wonder if the carb helped you though? With aftermarket exhaust I bet it will.
what exhaust did you buy?

The header is a pretty large ID, plus the one I got is tapered, so it gets even bigger

I dunno if the muffler you got will be like this, but it necks down to about 7/8" or so.

It looks like your pipe will have good back pressure for low/ mid rpm torque and its large enough to breath at top speed. Hopefully my exhaust is the same:cool: It might be a little too restrictive when I swap in the Lifan 150 though.

I checked out the gearing just now, 15t countershaft and 32t rear sprocket.

can the 140 maintain 8000 rpms for a couple hours? I'm sure its not good for the skyteam 125, but sunday I had it pegged for over over an hour at 7500 rpm and it was vibrating real bad. I'm thinking my lifan 150 would puke the con rod or pin after 30 minutes at 7500rpm​

No idea and I dont intend on finding out. the most Ill ever need to hold it WFO will be a quarter mile or so.

I'm looking to buy inexpensive rearsets. Does anybody have any reccomendations? I searched and all the ones I found were several hundred bucks.

Also, I've seen a couple kickstarter on different builds that had a lot of offset. I've looked around to try to find those kickers and can't find anything for the small 13mm or 14mm kicker shafts

I found cheap rearsets on Ebay, but they're for disc brakes Monkey Bike Z50 Jingcheng M50 Billet Rearsets Footrest Backstep Rear Disc Brake | eBay
