Hi all. Not been on here for a while but im back on my favourite little 400.
only problem is its blown up.I desperately need 1 je 58mm 3 ring piston. Been in touch with tts and they haven't got any. Anybody got any suggestions?

Yakama has a set of them....

What happened?

Dropped a valve(prob due to being reved to high)resulting in a massive hole in the piston.
Cheers for the pointer.ill pm him.
