Maybe we should have a look at Keiths 28, hasnt that got 70+ bhp???
Also like stephen said, my bikes engine has not been apart for more than 8 years, so a ring change is probably well over due, and its running a little rich to be on the safe side. Then again I still maintain my bike is quick enough considering how reliable its been and how limited the mods are....still standard air box!
Stephen said a ring change would get me a few horses on their own, I have some in the garage so maybe I will give it a go and see what happens.
