So the engine is a Rotax 237.
My next question would be, how interchangeable are pistons?
I am lead to believe this piston is the original spec, but I am struggling to see/understand what my next size up option would be.
The ideal would be a rebore and new piston, but will a shop be able to find me a suitable not-rotax that will work? Or am I limited to a Rotax shape that may be £££/impossible to find?
This is why I wondered about spreading the skirt a little and getting some more life out of the current arrangement before paying sums beyond the value of the bike.
Re: timings, you mean like retard the ignition?
So just leave it sounding awful and excessively rattly until something goes pop?
