Yamaha 225 piston questions

[TheRealFatShady]

I have a 1986 TT225 Yamaha dirtbike. It needs a piston.

Do these bikes use the same piston as any other yamaha bike/trike/quad? If so, which?

Thanks

ya the last bore is a 1mm over,, the same as the 1st bore in a beartracker...dont go with a high compression piston,,
