When I ordered my new wheels I asked Jon at UFO what yamaha bike had the correct (or close at least) speedo drive for my 18 with 120/70-18 tire. He told me a mid 90's FZR600. I did the research and found that this bike was equipped with a 120/70-17 front; close enough, at least better than reading 11% high which is where I was at with the stock speedo drive, ordered it from my local Yamaha stealer. When it came in it was a perfect match for the old one except that the hole through the center for the axle shaft was too small:bang head:
Brought it to work and gave it to one of the machinists out here to enlarge the hole to the right size; easy fix right?:eusa_dance:
Went back to get it from him that afternoon and the wino motherfucker DRILLED IT AND DRILLED IT OFF CENTER TO BOOT!:bang head: By about .040
He should have used and end mill I believe. Ruined the effin housing!:bang head:
I told him "thanks" (what the hell else am I going to say when beggin' favors?) and walked away pretty pissed.
So I got to looking at the old one and the new ruined one and discovered that the ring gear and worm gear appeared to be interchangeable form housing to housing:eusa_dance:
After drilling a second hole in the roll pin area to facilitate removal of the roll pin that holds the worm gear in place I got the new worm gear and ring gear installed in the new housing and I'm back in business:eusa_dance:
I'm happy now but still wondering;
What IS the correct model bike that has a directly interchangeable speedo drive? This would be the one that Boxxenstop or Wild bro's sells since I doubt they're modifying one like I did.
