last time I actually rode my quad it died just as I was done riding it so I didnt care and just thought the plug fouled. For christmas I recieved a new fmf exhaust so I put that on, and tried to start it nothing, but thought thats right the plug is fouled, finally about mid March I changed the plug, nothing. ok well its due for a top end I have the new top end in and everything seems ok with that.

At times it seems like I have a weak spark, I know its getting gas plug is wet.
I have yet to get a manual can somebody help me out with testing the coil and what not so I can get this thing moving again

 

here is what I have done, I have cleaned of the flywheel inside and out, checked all connections, tried 3 new plugs and cleaned the carb. Oh and I also tried a coil from a z400 I know its different but I just used it to see if it had a stronger spark, didnt appear to though. Bad stator, cdi???

 

It's deff got 2 be a bad stator or cdi box! get a light tester and work ur way from the sprk plug 2 the stator! disconect the stator test there by kicking it!If spark there then it's ur cdi...

 

I'm ordering a stator its cheap enough and now its needed, we were taking it off and my brother broke the backing plate for it, so we'll see what happens when I get that in there, I really dont want to buy a cdi though, 200 and some odd bucks ehhh well see

 

I might have a brand new one for slae is your stator didnt fix it. I bought it but found out that i never needed it cause it was my pickup coil, maybe you should try that first.

 

thanks but I already ordered a complete new stator assembly

 

it's very rare for a cdi to go bad. the new stator will probably fix it.

 

I sure hope so, I only plan to sell it, and cdi's are not cheap

 

Did you rejet it when you added the new exhaust? Sounds like it is too rich.

 

Wouldnt be rich, if anything changing exhaust would make it run lean, but that wouldnt be my problem either. I changed out the dg for the fmf. Either way I barely ever get the thing to pop as it sits, still waiting on my stator
