new guy with RXP mods questions
I have an 05 rxp and im thinking about putting an R&D c4 monster wheel, fizzle F1000 I/C, Fizzle 4" intake, 15/20r prop, and 42lb injectors..
already have the OPAS off (before first ride). questions is, do I need the 42's or bigger? and do I need a Fuel regulator? Ski has 60 hours too btw. 70mph on gps. hoping for mid 70's. or higher

welcome to the GH
yes you will need bigger injectors
IMO 42 are still to small but with a rrfpr should get the job done
also plan on a afr gage in your budget
whats your plan for the ecu

I was thinking about the AFR gauge.. been looking at the pods. think 50's would be better? do I need to upgrade the ECU? Was thinking/hoping I could do that next winter.

Cool, thanks guys..
Think 50's would be better? how much better is a new ECU?
which pressure do I set the RRFPR at? 65? and not on rising either correct?

New ECU means valve train upgrade. If you have to draw the line for a modification budget I would save the ECU and bigger boost for later and do a 10 psi wheel for now along with the rest of the list in your first post.

I would change the valves as they are a known weakness and also the flywheel bolts. Demanding more power out of an 05 motor can easily cause the valves and flywheel bolts to break.
