Hi.

I am having problem with my 2007 IQR. I have 2002 800 BB VES in it and Race Pipes, the motor idles ok, but when i rev it up it sounds like it's drowning and wan´t hit full rpm. I have already changed CDI box, stator, ignition coils and swapped in another throttle body with no luck, always the same. The motor has 130 psi compression on both cyl. when it´s warm.

Could this be the timing or some thing else.

Any ideas guys ?

Throttle body? You mean set of carbs?

Normally when I hear about an 800 having this sort of issue its one of a couple of things.
1 - Temp sensor
2 - Torn/leaking exhaust bellows

That is assuming its jetted pretty close to what it needs to be on the mains.
