Jafa rides again! Briefly.

Heads are off, and one piston is holier than the Pope, plus the ring is sticking up and out, and the cylinder barrel (barrel? bore?) is a bit damaged.

Probably best to go for a rebore - I just need to measure up pistons to check if they are stock or are already oversized pistons, to see if this is viable. Unforrtunately a evil combination of work and physio leaves me very little free time during the week - but that is not a excuse! I'll check in the next couple of days.

So it'll probably be either a rebore or new cylinders from Ebay - any good places to get a rebore done?

All good, at least process is underway and a plan of action is in the offering. Don't let Daisy side track you from the grand plan of once again having your 350 ring a ding dinging around the 'hood!

Carr Engineering in (duh) Carr Road. And the RD/RZ 350 can go to a tenth oversize (+100 ) with aftermarket pistons , so it is very improbable that you wpon't be able to rebore (there's a few gotcha once it gets past +60 )

EDIT : I forgot to say that Mr TonyB , on here, has good pistons cheap. In all the oversizes. Also forgot to mention that Carr Engineering understand two strokes. Which not all do. Still, even so, don't neglect to relieve the ports on reassembly.

EDITY EDIT: It is mandatory to post a big picture of the mangled piston in the Ringa-dinga social group, to join all the others (worryingly, I think they're all yamaha, too)
