hi,paul
Thanks a lot, those infomation are really helpful to me. appreciate..
About the Wisco pistons,I sent my stock NSR piston to Lio in Wisco, they helped me to match it. when I got back my Wisco pictons, they are forged and beautiful also exacetly same!! perfectly matched and I don't need to mod them. But when the engine started, the RPM has little bit higher, Is that normal I have pic that I took to compare with stock piston, they use Kawasaki 125 cc to match, if some one need pic info, page me a message, i think it will wake up your NSR.
I used to contact with Jamie in Japan, I got some NSR knowledges from him, he is a very nice person and knowledged, hope Jamie is on this forum to share with us.
