1978 WR250 17 inch wheel and other questions

You will find the OR frame has 30.5° rake while 78 WR, CR, & Auto frames all had 29° front rake. You should not find that much lees steering reaction with the OR frame as long as you keep the front fork length down to the 77/78 35mm average length. If you put lights and speedo on it, it becomes a WR anyway.

Thanks Jim, I'll measure that angle, I would like to know just for kicks. Crank is rebuilt, cylinder bored, and I received a pristine set of 2066 cases from a nice guy on Marks Swapmeet. Motor assembly can now begin. I'm on swingarm #3 as an ebay seller did not correctly identify swingarm #2 that arrived a few days ago....luckily he has another that he thinks is a match and he will swap it. Hubs were powdercoated last weekend and sent out to Buchanans. Progress.
