Won't start
 

Tried putting on aftermarket coil,AMR, wouldn't start. Put stock back still won't turn over?

Oh yeah, '03 lt 50.

More information on your problem would help people better assist you on your problem.

Model, etc. More detailed description on your situation.

won't turn over huh? well, put you multimeter/ohm meter on the battery and see how many volts are on it just sitting there. should be roughly 12.6-13.5. close counts. as long as it ain't under 12. if under, then charge the battery. or you can use your car and jump it off. once it turns over/cranks the engine, is there other problems? won't idle, won't rev up, etc? well, that's a dirty carb/jets. if battery is good, does it have a fuse on the positive side heading towards the starter? sorry, not familiar with your quad whether pull or electric start. you didn't give much info about any of the problems other than won't turn over.

It's an 03 lt50. Did some upgrades, intake, exhaust and rejetted. First screwed up the jetting but finally got that figured out. Plugged oil. Still have straight fuel in when I put AMR coil in. Just wanted to see if it was going to turn over, not run for any period, before I switched to premix. It wants to start but just won't turn over. Pulled brand new plug and connected it to coil and I'm get some spark. Not a lot but spark. Acts like when you try to start it when you left the kill switch on. Pull pull pull but no ignition

Hmmm, check your ground on your coil. When you pull the plug is it more dry, in between, or more wet? New coil etc, hope its not a stator being an 03 it most definatly shouldn't

I'll check the ground when I get home in the morning. Plug is dry. It's a coil, looks just like the stock one. I Put the stock coil back on and it did the same thing. Makes me now rethink the ground. Hope that is it.
