    66V PV engine to 65U Non-PV conversion

    Im considering converting my 2001 XLT 1200 PV (66V) to the 1200 non PV (65U) engine, what is necessary to perform this conversion? Will i need to fab up any exhaust pieces or can i use the original exhaust from a 98 gp1200? What about the PV servo wiring, can i just leave it disconnected? As for carb rejetting specs, can i start off using the same specs as a 98 GP1200? And will I be able to keep my OEM driveshaft?

    Hoping I can keep my cases but im willing to swap it all if that is what it takes

    Completely different engines, not to mention electronics (cdi etc.)

    Have you considered selling the 1200 cylinders and power valves, then going with the 1300 non power valve cylinders.? In this way, the modifications are much smaller such as rejetting the carbs and having your stock head (domes) reshaped. You even get to keep your cases and use your stock exhaust.

    Or just find a FI 1300 with the ecu and harness.
