Hi

I would like to know if you tested this hi compression piston and if you noticed an important difference

it's for +1 rebored cylinders (diam 68 instead of 67) and compression is 10.5:1 instead of 9.5



Please let me know

Thanks

Cheers

You may get more response from a Japanese language TW site.

I don't know the price you would pay to rebore a cylinder but it would be interesting to use this piston instead of a genuine +1 one.

Cheers

I looked on the Wisco site and didn't see any pistons for the TW, what piston did you use?
