whats the rubber cap with the spring clip steve is that for coolant
its the rave valve garry, works off exhaust pressure which lifts the valve up and down to alter the exhaust port timing, gives more torque at low revs and more power at high revs, a bit like a turbo on a car, first test ride was Saturday and its very very quick, did a power wheelie in second gear without even trying, its got way more power than it had before, and that was 35bhp, I still have the bigger carb to fit as well, that will got on when I get martin at chiselspeed to dyno it for me, I just want to get some miles on it first.
