Try reaching out to Murnan he might be able to help you out since he does a lot of mods on RB's He might have a P/S set

I send an email yesterday and this morning got a response! great customer service! I'm considering letting Uriah modify this motor if I decide to buy new P/S set.

I tried swaping pistons with the V12 unfortunatly they are not the same. V12 piston won't even fit inside the R3 sleeve.

That's not a bad idea since the motor wasn't very old. A new P/S, Uriah's mods and you have a killer motor for a bit less than buying an all new one outright.

Oh I know! it was actually my idea since I have the V12 just laying around...

Well the cranckcase, carb., P/S, crankshafts are very different between V12 and R3 I just figure I would be able to change pistons since they are both RB engines. To my surprice the R3 piston is slightly smaller than the V12 :D

Hello everyone! Just wanted to share some pics of my R3 modified by Rick Brake! he really hooked me up, let's just say I paid less than if I had purchased a new P/S set.

He installed a new 5 port novarossi Piston and Sleeve, new front bearing, modified crankshaft, sleeve.
