thinking about it Cal, you're right i can turn the power valve with a bit of plastic so i must just need a servo, which is best? are the easy to wire in?
ypvs is the hole system you will have the valve just no the servo.
the servo itself it straight forward to attach the plug socket will be there you just need to unbolt your end cap put the new one on with the housing and cables to the servo and bam your done.
as for getting one yes i will say yes to everyone that is how the bike was made you have the best of the bottom end and best of the top non of this bs some people say no no no pinned is better its bs with it pinned you get half the power.
but be warned depending on the year it might be a 3 wire or a 5 wire if its a 3 wire there rare and cost a pretty penny to get one but 5 wires are common and you can pick one up and feel the power =]
