hi all

I just bought a 2007 rincon 680. At about 18-20 mph the quad bucks and feels like it is hitting a rev limiter and pops loudly.

I got the right spark plug no difference

Changed oil no difference.

In automatic mode it does it as soon as you try to give it any throttle.
In ESP mode it does it top of first then you shift and it goes away then it does it top of second then you shift and it goes away then in third I can only get it up to 37 mph. :dunno:

Any more ideas would be great

Thanks, Peter

This transmission is very complex and requires various inputs inc engine speed. You are best to go to your dealer (I know thats $$$) but it is very easy to stuff the ECU if something does go wrong. And thats even bigger $$$.
Have you tried pulling off the connector plugs and replacing them? Amazing how many faults this fixes. A small amount of crap causes major headaches with all electronic controls. Water is renowned for this.

The quad also does this in neutral when you rev it up it's like it goes on the limiter. So that is why i don\t think it's the tranny.
