pre '70 rti
« on: November 25, 2008, 11:38:31 am »
my rti siezed half way through the 25 lapper at the nepean two day meet.the problems per list 1/.i now have 2 barrels and pistons that are rat-s!!!, and max oversize. 2/.the only financial supply is the o.a.p. [plus occasional lurky cash jobs].QUESTION, does any one know of a piston that is a bit bigger out of anything else that i could have my barrell bored out to take?the class is pre'70 500cc so big bore can only help make up for ability! cheers wally.

..., is it reed or non reed ?



If its running as a pre-70 bike, then its non-reed.

I bought a stack of Yamaha pistons from jgroom888 on US Ebay, and paid SFA for them - but they only go to +1.00mm, and I keep forgetting to look for the larger (after-market) piston kits.
