Wheel Truing Tolerance
« on: October 05, 2014, 03:12:25 PM »
I'm working on Truing up the Front Wheel on my 750 K6.

I've gotten it to the Following:

Between the Forks it is 0.55 mm to the right of center (as you're sitting on it)

The Axial runout is down to 0.44 mm  (side to side)

The Radial runout is down to 0.64 mm

I think maybe the wheel needs to come to the left just a hair more

Would like some opinions as to how close I am to having the wheel Trued?

Thanks,

Charlie

Yes..........wheel left...........all else is good for a street bike.  The real test of your work is to check it after several miles and a few bumps.

How are you measuring to center.. Dont go off the forklegs..I mean day nt count on them being same thickness.. Sounds like your wheel is pretty good.

The rim might have a bad area too, not possible to correct. The weld where rim is closed has a bump. One of my rims worse than the other. Both new DID rims.

Thanks Guys!

I'm going to mess with it for a while today and see if I can get it a little closer to center.

Did not see any spots where the dial gauge took a sudden hop, so I think I should be able to tighten it up a bit closer on the centering.

Thanks,

Charlie

Truing mine right now. How do you measure to center?

dgilling,
Per Hondaman's book, I started with truing the wheel by using a straight edge across the rim and getting the hub as close to even on both sides as I could.  Measured the distance between the straight edge and the hub with my micrometer.
Then according to Hondaman's book, you need to find the centerline of the bike and mount the rim between the forks.  As far as I could tell, the centerline of the bike should be the center distance between the forks.  At least that's what it worked out to for me.

Then I simply held the dial gauge against the rim on both sides and checked for axial runout on both sides. 

Hope this gives you what you're looking for.

 My rim had a wide spot at the weld. I whacked it with a plastic hammer and it was way better.
