Speedo is out

15 Aug 2008 13:00

I put a zx9 front end on this winter. I just discovered the speedo is out by about 12 miles/hr.
I had to change the threaded end on my kz cable to match the threads on the zx9 speedo gear at the wheel.
I just assumed that the speedo would work right.
any suggestions?

Add or subtract 12 mph from or to what your speedo says. I know I'm very wise! :blush:
Is it because the wheel circumference is different? Prolly a stupid question...and no help at all. :(

Yes the wheel is a 17",but i thought the gearing in the stock zx9 speedo drive would take care of that. there must be a diff ratio from the zx9's wheel gears to the KZ's speedo gears.

Sounds like you may be a candidate for a GPS speedo thingy.
