Power Valve difference?

[dquarton]

Can anyone tell me if a "Rotax" style power valve (like the ones used on Duncan PC2000 cylinders) is any better than the ESR or CT aluminum power valves? Is this newer or older technology?? Looking at a bike with a BB motor that has one and I have never had a motor with that kind of PV.

Thanks!!

i asked the same question a few weeks ago and was told that ct and esr are just newer versions of the same thing.

The Rotax ones are the best ones available for the R. Run a synthetic oil to reduce maintenance.
