Did they ever replace the wire harness? I would honestly take it to someone that knows what they are doing. With a meter it should not take them long at all to track down the problem. After i rebuilt my whole harness and still had a no start issue took me 10 min with my meter and found out the wire on the back of the ignition switch was holding on by 1 strand. If i can do it that fast a shop that works on these things for a living should be able to do it in less. Heck when i did it it was -30 working outside under a tend. they are in a heated shop with it up on a lift..hehe

 

Yes, well they told me they tried everything with 2 different components including the wire harness. They said they ordered one and pulled one off a quad in the store. The guy said he has been a "master" mechanic for 30 years and this one has him stumped.

 

What kind is it? I had a JetMoto 250, and aside from having to loctite everything as I assembled it, and one initial carb issue, that thing ran GOOD for what I paid for it. I felt like I got a deal on it after riding it for a month and then selling it.

 

whats the issue? no power?
easily checked,witha good battery,cross the starter relay contact witha screwdriver and see if the starter spins.
if it does,it can be cranked.
if it doesn't spin,you either have no power to the relay or the starter is bad.
