This thing has a wierd grounding issue. It will only start if Im putting down pressure on the spark plug boot and standing on the ground. It I dont have ahold of it, I get nothing. Doesnt even turn over. Ive chased the grounds down and cleaned the areas up. This thing is driving me nuts.

 

You can try adding a extra frame to motor ground wire.
Also, Ya know, the stock spark plug caps are junk.

 

its just wierd. The starter wont even turn over unless Im hold the start plug boot

 

I guess so. The spark plug has nothing to do with starting.
I suspect you're right on a ground issue.
Try the extra ground wire. I go from the brake line (where it bolts to the frame) to one of the motor cover bolts.

 

so after several hours of chasing the problem, I broke down and bought a new wiring harness. That ended up being a big waste of money lol. any chance the starter can be grounding out? if I unplug the power to starter the relay clicks il I touch the frame with my hand. When I touch frame it does nothing

 

if it could be starter what after market brand is decent, thanks

 

The extra ground wire didn't help I take it.
Ok, are you sure the positive and ground isn't backwards?

 

I just got this quad, so anything is possible. It fired right up when I bought it but has been down hill ever since lol. Besides the wiring harness, I also replaced the push button. I have not a clue what it could be. Ill keep researching.

 

Beats me dude. I've mentioned things to try..

 

well i got it fixed. it ended up being the the park brake wires were bare on the frame.
