I bought it 6 months ago and was told it needed a top end rebuild but what i didn't know until after I bought it is that it had previously cooked the ecu he got it replaced and it didn't run good he sent it back to the bike shop and they said it needed a rebuild but I found that the fuel pump was the reason it didn't run good so I replaced the fuel pump fuel injector spark plug wire because it was bad all of which as fixed all of the other problems and I wasn't that worried about this problem since it runs fine ones it's warm and I've put about 1100km on it but it would be nice to fix Thanks

Yeah checked for trouble codes. How to I check temp sensor reading Year is 2006 Thanks for your help

I've done everything other than compression test and valves. It idles fine but when you give it throttle in gear moves really slow runs roughly and dies but if you let it idle for 5 minutes or rev it in neutral until it stops running rough because it doesn't die in neutral it works fine. Thanks

When it smoke's it doesn't run rough but it doesn't smoke that often and it doesn't always run rough.

I've put a new plug in and didn't do anything. Should I try a hoter plug?

My king quad 700 runs rough when cold then won't start some times but not often when it's hot. And occasionally smoke's a lot when it's cold I'm guessing that's rings but I'm worried unless it's causing the other problems All help is appreciated thanks
