I have a 93 honda cbr 900rr with 122 1/2 main jet,does any one have any idea where to set the screws,they are 1 1/2 out now,any help on setting the screws would be wonderfull. Thanks

 

usually about 2.5 turns out is a good baseline. To set it really accurately though you need a tuning tachometer, something that can read in 50 RPM increments. I will not try to quote my manual from memory, refer to it for the exact procedure on how to adjust.

 

you need to start at 2 out and then go in quarter tun increments but a set of vacuum guages would set you up as well
