I'm upgrading as well. I have a 77 gs750. What are the ratios, or where can I find the info? Last bit needed to get my bike on the road again. The sooner the response the better. I'm itching to get back on two wheels!!

Cheers

Hi,

The number that comes up most often for the speedo is 2240:60. For a mechanical tach, the most popular number is 1:4.

Hint: Search "titles only" for "ratio".

AFAIK, most (all?) of the GS series use the same ratios. On my 850 speedometer, a cordless drill that was marked as being 1500 rpm showed up at just under 40 mph, so the 2240:60 looks right.

On the tach, I seem to recall the same drill ran the tach to about 5000 rpm, but then again, it's been a while. Or the battery was running down....
