Thread: Question for the mechanically minded

The problem stems from the boost pressure always trying to push the reeds open and pushing crankcase seals out.
Would need to flipflop double seal it..
If you really wanted to do it, then a 800 seadoo jetski engine with its rotary valve timing would be the best way to start - 110 hp factory and variable heigh exhaust ports.
A 4 stroke seadoo engine with a ecu flash and bigger blower puts you well over 300 hp. Slipper clutch and tie your nuts to the handlebars!
There were kits made for the banshees and most people fitted RZ350 engines to them as they were same same but with electronic power valves.
There is a good reason that they didn't sell heaps of them and are no longer made.
If you can run a 4st, a road bike engine puts you waaaay ahead to start with.
