Piston sizes

Post by Skinnybob46 » Sun May 19, 2019 8:01 pm

Hello, looking on Wemoto.com for replacement pistons, there's A,B,C and D of slightly different sizes can anyone advise. The barrels haven't been messed with. Thanks

Your barrels will have their size letter stamped on the top of the exhaust manifold.

Best measure the bores first, then use the measurements to choose the piston size.
