Please help someone! new here!

i am used to working on dirt bikes not a Chinese quad . i bought this for my son and it had some issues ......it starts and goes forward since the picture above i have stripped repainted and ordered all new levers lights , cdi etc etc all universal because i cant identify the thing!! other than the motor is a Loncin 200cc the gear position sensor is broken. the wires were hanging anyways it has a rear disk and drum front brakes.

i cant figure out how to engage reverse.
i cant find a wiring diagram anywhere or replacement harness
when i hit start it keeps trying to turn over with starter i have to tap starter relay for it to stop.
i cant find a new front sprocket guide etc etc etc i will post many pictures thank you

 

 

 

how it looks now

 

ohgrr...LOL

 

Why do I suddenly feel pain when I see all the quality street bikes along with the XL Honda just sitting while all the work is being done on this quad..

 

A Polaris guy bagging on a chinese quad. Now that's something.

Sorry OPT, couldn't resist.

 

How do you know it even has a reverse? Not all quads have a reverse. Do you have pics of it with all the plastics installed? This may help better in identifying the make/model.

 

there was no plastics on it when i got it , yah i know all the real bikes around and i am messing with this thing, but it is for my son.. the guy that sold it to me moved it in reverse and i did it once accident but i have no idea how .
