hi all . ive got to the stage of jetting my 1989 gixer 750 k but before i start beating my head against the wall i will ask your advise . i have cone shape k&n's and a slightly shorter race can other than that its standard . can someone suggest jetting changes ( if any ) i will need to do or is there a ready made kit ? im running out of money so if i can get away with doing it on the cheap that would be even better .also places to buy the parts would be good .i live in the uk .ta muchy burt .
