More (somewhat usless) info on Pilot "big bore" mods.
I have a Pilot cylinder that has a bore measurement of 3.354" (85.192mm). I've found the following pistons but have no idea if they will work. I also don't know any of the pin height measurements of these pistons.
Polaris 400 (x2 over stock) measures 85mm
Suzuki LT500r = 86mm
Kawasaki KX500 = 86mm
A 3.346" diameter (85mm) piston would give a piston to wall clearance of .004". and create a 450 cc displacement with my jug. Is that too much?
I don't have the time or ambition to mess with it at the moment because my pilot is almost brand spankin new (I just changed the rear break pads that were put on at the factory). The jug and head I have are for sale if anyone is interested. (
