Im going to be putting a stock 760 and electonics from a wb2 into a RN. Obviously the enourmous exhaust wont fit in the RN, and I dont have the cash to build the ski the way I want it now, so im just going to run it stock until I can do it all at once. I want to run a stock 61x exhaust for now, but does anyone know if swapping the exhaust will affect the jetting. Im kinda going for simple here and not have to deal with tuning issues.
