agree with the rust sheild m8 lol i got told that if i up jetted then itl be more responsive in guna put a race coil and a couple of over thing on it aswell
what jet do you have now ? up jetting may make it a little more responsive but it could also bog down its sort of trial and error m8 cos not everyones bike is the same
there are 2 different sizes as standard the 210 for the 88-89 model and 240 for the later models tbh i would leave it for now m8 and get your coil and other bits sorted as i dont think you would need a jet change just yet :)
