rave valves

[daniboy32]

Was wondering if anyone could tell me if there are specific rave valves you put in with an 880 big bore in a 2008 xp and how they are suppose to be adjusted if they don't have the red cap on top, should they just be sounds in all the way or should you back them off a little for certain conditions? Thanks

I'm by no means an expert but I'm pretty sure that if its bored out the raves need to be machined to match the new bore. As for the other stuff someone else should be able to help you out. Who's big bore kit is it? They would be able to tell you for sure what raves the engine requires.

Have to be cut to match bore and porting. No red caps as the 800R uses electronic solenoids to operate them.
