i am familiar with tweekin full size engines and was wondering if anybody has tried knife edging the con rod then balancing the rod against the crank weight?
Also porting on the piston sleeve any advice on this?
is there any benifit to port conditioning and tear dropping the feed hole through the crankshaft?
is ther any benifit to polishing the carb venturi?
and the last questioon is about compression. so if you remove a head shim you have to run a higher % nitro or is it the other way around?
i am running a hpi T15 i like it just wanna get a bit more out of it.
