I know many of you side car fans run xs650s, so maybe you have some ideas. I am building a vintage flat track bike (ahmra legal just in case) but for now am trying to keep the project cost down. Any low cost ideas for getting the most out of the engine? I checked all the usual sites (Mike's XS, XS650 Society, ect.) I don't want to rephase, and want to keep the original cylinder liners. I know I can overbore to as much as 1.5mm over (6th oversize). Any body know where I can find some NOS Venolias high compression pistons?? Thanks in advance for the Ideas. Kevin
