Re: Mixing Castrol r30 castor with synthetic oils
By removing the bottom gasket you mean the gasket between the cylinder and the crank case ? That sounds like it will boost compression a little bit, but at the same time it will change the timing of the engine, I mean at how many degrees the transfer ports open, and when the exhaust port opens, etc, just slightly though. I've no idea it that is good or bad but it'll be changing it. Removing material or a gasket from top of the cylinder shouldn't affect the engine timing. I think the timing in these engines is not optimized at all, I'll look into that in the near future, I'll keep you posted.
