hello all, ive just brught a 1990 gsxr 750 for my wife, and i have to say i love it as much as my zx9. i understand why it was called the nutters bike, its ace. anyway, ive just stripped and cleaned the carbs, im going to but a carb tune kit to set them up but am readind conflicting information about how set them up, some web sites have said that no,s 1 and 4 are set with a 2-3 inch of mercuary differance, but the haynes manual says set them all the same. also has anybody used theese new colour tune plugs with the clear top to set the mixture, what are they like, is the mixture adjustable on my uk spec bike, cheers john. oh yeah if anybody lives in devon and wants to come for a ride, let me know.
