Thank you.  I'll spend about an hour to hour and a half on a wheel. It's therapeutic for me , so I don't really rush/push it.

Dang, that's pretty quick. Lacing/truing wheels is a skill I do not possess.

Thank you. I spent 15 years in the bicycle business , and building wheels for some of the local motorcycle shops and riders. I had ample practice.

nice. That jig on your bench looked like a purpose-built unit in your picture. I have a question you may be able to answer with your expertise: are there any offsets used on USA RD air-cooled wheels? Reason I'm asking is I relaced a handful of bicycle, then motorcycle wheels over the decades and always just let the wheel kind of "center" itself in whatever jig I had rigged up tightening spokes small amounts at a time evenly as I went around the wheel and pulling left or right as needed to spin true before final tightening all around. Never had a noticeable problem with this method.

Some years ago I met a friend in the VMX community who lived nearby and would lace up a wheel for me for very reasonable price and warned me about using correct offsets when doing myself? I never heard of such a thing but he insisted he always used correct offsets and got specs from wheel builders like Dubya. Was he telling the truth or blowing smoke on this?

as far as offsets are concerned, I have always set up a wheel on my truing stand and brought my new rim to the same position as the old. I am sure there are some offsets on some wheels.  so I just use the original as point of reference for position of new on.  The fixture on my bench is an Artisan antique wheel truing stand it is at least one hundred years old. I have owned this stand for 27 yrs. It is missing some its components but I love it..

How will it work when I set-up the position of the rim,to look through the valve stem hole and adjust the rim to the exact center of the hub,in reference to inside both flanges ?

RustyRD

several tools and methods to check offset. here is one. bicycle or motorcycle the rim can be checked for center placement once mounted, and if needed the rim shifted by tension of spokes to make corrections.

It's such a pleasure doing business with Yambits. I placed an order on the 3rd and received it today the 7th.  :whoop:  :whoop:  :whoop:

Russ, does(when using that dishing tool you posted)the RD250/350 have any offset in the rear wheel,or is it neutral ?
Do you also 'center' the rim in the swingarm.. and does it match the centerline of the frame that way ?

I set my stand up with original wheel and proceed from there.
