Rpm

[Caper11]

everyone makes the same point but my question is why.

Why do they chose to run more/less rpm and is there gains to be had? you rarely hear about ralphs/linderman porting anymore.

anyone run more or less rpm than suggested and clutch for it?

As far as a two stroke engine, there are alot a variables, engine design, pipe.

I found this article for you. Its a good read, and I do miss the snowtech magazine articles.
