Sprockets

[Mark]

Im looking for someone that may be able to help me with a gearing problem that Im currently having! I have a 1979 Cb750 four and I installed a new 1980 Cb750 Engine in it and it is way low geared. Does anyone know what the correct sprocket combination would be to make it have the right gear ratio? Thanks for the help!!

 gear ratio is really the owners preference, i have a 82750k and was not happy with the stock gearing, way to low geared, original sprockets on mine was 18 tooth front and 46 rear, was revving way too high for mph i was getting, so i switched rear sprocket to 39 tooth, shortened my chain and i love the gearing, still launches off the line and i can cruise at high speed with out destroying the motor, these motors are designed for high rpm but stock gearing was just rediculous, good luck, mykey440
