Changed the rear sprocket from 45 to 48 teeth, changed the front sprocket from 17 to 16 teeth.
I might have gone to far. I bought a Speedometer healer to correct the Speedo. At 80 mph Iím running about 5900 rmp.
Not worried about blowing it up, itís a Honda. Cool
What is everybody elseís RPM at cruising speed? Question
Would you like to change it? Question

Notice that Ralph didn't give a "cruising" speed, speedometer was probably pegged.
