I picked up 2 ty250's at the beginning of the summer, one is stock bore and one (the ex pro bike i was told) has about a 300cc or so piston in it

 

I wonder if a IT400 piston would fit?   :o

Overbored TY250's were popular here in the UK. Coming out at nearly 320cc, I suspect that a 400cc piston would have been used.

Some tests here of the Majesty TY320 : http://davestestsandarticles.weebly.com/ty-yz-mx-sc.html
