Any one have experience with cheap chinese pit bikes?

[turtle13]

So I picked up a cheap Chinese pit bike from a buddy of mine to use its 125cc engine in my c102 and I'm not exactly sure what a part is on the bottom of the head. It sounds silly, but since its not running right now I want to make sure every thing is hooked up right and running before I bolt it in.
It looks like an external oil pump at first glance, but on these engines it is usually internal in the case and not on the side of the head. The line that's going out of it doesn't go to anything and looks to have a pcv valve or filter on it...
any ideas?
I will try to snap some pics of it tomorrow when I pull the disgusting glob of dirt and oil off of it that could pass as a Carb to clean it tomorrow.

the silver piece on the head is said gizmo on this engine. it looks to be vacuum operated off the intake manifold pulling oil from the bottom of the head... but where the bloody * does it go?
It looks to me to be some sort of emission control or something, so i am assuming i can get rid of it, but since i cant figure out who makes the thing i cant find any parts diagrams to see what the thing is...

The gizmo looks like a PCV system to me. The line to the intake allows for the fumes to be burned for EPA regs.

I've had some chinese pit bike motors, but none with the doogamafloppy.........agree with eliteguy.....pcv system that go into the circular file...........

I'm thinking the same thing... ditch it and just make a block off plate where the nipple comes off the head.
Now I just have to get it started... kinda hard when its so small and the top of the tree is broken.
has any one swapped out the stator in one of these for one with a lighting coil? Is it just as simple as pulling the old and putting in a new one? I don't believe this engine has one, but there are two leads (yellow and white) that aren't connected to anything...

Block-off Kit

So the madass has all the egr crap? Maybe this pit bikes newer than I thought... still wish I could figure out who made the motor.

[wiguy05]

Only the California Madasses have the emissions junk. Everyone gets rid of that clunky crap anyways. lol

Check under the engine, near the shift lever output shaft. There should be a serial number for the engine there.

Questions.....this chamber obviously gets some valve stem blow-by and that's the reason for the egr set-up......first...Where does the pressure go when utilizing a block-off plate.....and second, why not just route in into the atmosphere ?........................

post a picture of the whole bike. my bet is that the motor is a lifan motor. BBR makes alot of stuff so does kitaco.

[eliteguy50]

i agree with motormike. use a filter to the atmosphere. that way you avoid oil contamination.

i had a 50cc dirt bike couldnt find parts for.... turned out it was a honda replica motor and suzuki plastics... after that could get every part i needed... do some research on it... those things are either Frankensteins or replicas....

It is definately a honda crf clone, just cant figure out the company that makes the motor.

in my case, i just went to honda for parts... it was a pantera dirt bike... found out bajamotorsorts.com sold everything for it (parts where more than from honda) but they called it something else.. look for other bikes that look the same and go from there... google man its amazing...

My Frenchy bike has something similar, it went to the exhaust pipe. So when i got an aftermarket exhaust I just plugged the hoses :3
