Default Re: Mixing Castrol r30 castor with synthetic oils

Yeah that would work just as well, actually it is superior but I don't have the tools to do that. I did spend and hour with a piece of glass and some wet 'n' dry glass paper but barely shaved anything off and was starting to curve the surface. The spark plug is fine but you have to leave more clearance than first thought because there is up and down play in the piston. You can't have the piston smacking into the head even lightly. Noticable boost in power though. Had mine done so long ago I kind of forgot until I rode another bike recently. No change in performance acceleration-wise or anything so it is mainly noticable up hills or into head winds then it just trucks
