Hi there

Back again with more questions

Got the chance of a bored out Cub barrel but don't know which piston to use?

The Barrel is 68mm from 63mm & I would like to avoid any issues with a change of stroke. Is there a straight replacement at 68mm?

Thank's Frank

    Oversize C15? A C15 is 67mm standard bore, but not sure about pin size, piston height etc. relative to the Cub

    Triumph 500 and 650 pistons will fit the C15, so maybe the C15 will fit the Cub?
