gear ratios

[Dick Eastman]

Are the gear ratios in a Scrambler tranny the same as a Superhawk?

I have a factory CL72 manual that says:

Crank to trans - 3.133
1st - 2.788
2nd - 1.661
3rd - 1.171
4th - 1.000

countershaft sprocket to rear wheel - 2.625 [this works out to a 16/42].
I thought the chain sprockets were 15/37 for the CL77, but I am not sure, as this manual is for a CL72, and has a date on the back cover of 1971.

Does the Superhawk run a 15/32 stock? If the tranny ratios are the same, then the chain sprockets are the only difference?

Thanks,
Dick

CB and CLs use the same trans. CL77 15/37, CL72 15/40, CB77 15/32.

Thanks, I had forgotten that little fact. I want to set my CL up to similar gearing as the Superhawk. I will need to determine the circumference of the rear tire for the two models to see how many teeth the rear sprocket needs to be.

Thanks, Davo. With the 18" vs 19", I'll need between a 32 and 37 T rear sprocket.
