The thing is I have often thought about doing this to my bike. My engine is an 853 and gets a shift on very nicely so i reckon it would turn my bike into an animal.
Perhaps i will do this next time a need a chain and sprockets.
DC.
If you get a quick release sprocket carrier then it is really easy to change to a different sprocket if you don't like the set up.
The sprockets are alluminium so only cost £25 each.
