1969 CL450 US Barn Find Restoration
MrDavo:
I didn't get much done this weekend, what with Marsden Jazz Festival and the PCGB's Peak District run on Sunday in the 911, but I did get the front end on...
What we have established so far regarding the forks is:
There seems to be a difference between CB and CL yokes, probably different geometry as suggested by K2-K6.
To add to the fun they changed the CL yokes at least twice, my parts book shows the numbers change at 1012469, which is prior to my K2 number. We have established that my bike is a K2 in K1 clothing for some reason, which suits me as it looks much better for it.
My (sold as) CB450 K1 top yoke doesn't fit. Possibly its wrong on two counts, then, CB, and K1!
Although I have a broken instrument mount, what I do currently have is a matching front end which all came off the same low mileage bike. If for example I fitted James' K1 yokes, I'd definitely have a matching pair, but mixing K1 with late K2 may not work - the forks would (probably - there seem to be different fork tops too)) fit perfectly but would the front axle or the mudguard still fit?
I think you'd have to have the parts in the same room to be sure, can someone suggest an accurate way to measure between hole centres?
You see my dilemma, however I'm not too fussed for now. My project end date is next November, the bike's 50th birthday, I want her back on the road by then, someone will break a late K2 before that date, I will be watching the web.
Bryanj:
For centres measure from the outside of one hole to the inside of the other
MrDavo:
Thanks Bryan, that makes sense.
K2-K6:
If using a vernier caliper, you can just clamp it bore edge to bore edge then add one diameter to the measurement (as you are missing two radii) that'll give you the centre to centre number.
Just turn the clamp bolts on the yokes to set the diameter to that of the fork tubes first if they've been wedged open to get the stantions out.

Dave - assume you don’t need the set I have here? J
