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

Mame Shiba,



Perhaps you have received no replies concerning this piston because it is a specialty item produced in Japan. Few of us live in Japan, and there are far more affordable options produced domestically in the U.S. and Europe.



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

Hi

Thanks for interest

well, basically it's an affordable way to increase power on a TW200, piston kit is 12,600¥.

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 didn't use that piston but I did use a Wiseco High Compression(225cc) over size ... I use higher octane and I've put on 2,500 miles on the rebuild ... Putting in that 200cc H.C.forged piston seems like a better idea than all the work I did last winter... If I had another TW I would ..

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

It was for a YTM 225 but there were ones for a 200 for around $100 .. Go to eBay and type in Yamaha 200 piston and see what happens..

Thanks, I won't need a piston for a long time, just interested in the possibilities.
