Need motorcycle Piston machined please.

Post by Otis0 » Tue May 06, 2014 3:31 pm

Hello, thanks for looking at my problem.
I have 250cc Yamaha motorcycle engine that I want to put 350cc Yamaha cylinder on.
I am looking for a machinist to change the -Yamaha ymf350- piston pin, or wrist pin bore from-- 19.00 mm i.d.-- to 20.00 mm. i.d.

I know that this has been done before, as the swap is documented online. The only hard part is getting piston machined for 1mm. larger pin.

I will send piston + pin. Let me know what you want to do it.
Thank you Otis0
