When my atv is in neutral it idles nice but when i put it in gear and just let it sit there it will lurch forward every time the engine fires. It doesnt actually move it just kinda rocks forwards and then rolls back that short distance. Then if i go back to neutral the rpms go up. Is that normal? Its like its trying to move in gear so its under load and then when i put it in neutral there is no load so it starts to idle fast. Then when its idling fast if i put it in gear i go lurching forwards. The thing that throws me off is that before i start shifting after its first started up it idles good.

 

Another weird thing I thought I would add-

When the key is in the on position while running the RPM's are high but if I switch it to the off position while running they drop to a normal level.

 

Any ideas on either problem?

 

It sounds like you need to set the clutch free play or your idol is turned up to high.

 

mine did that too because my idle was really high. it should be on the side of the carb where your throttle is. its just a **** and play with it until its where you want it.

 

it definately sounds like a carb tuning problem, id check for air leaks
