Hi guys. Top triple tree clamps are broken. Does anyone have one? I do not need any other hardware. Thanks!!

I'm 99% sure that I have one that I bought from another member, but will likely not be using since I have a CB550 front end for my project now. I'll check when I get back to my place on Sunday/Monday.

Just to clarify, this is the triple tree I'm looking for.

Real common problem on later models but the early ones had spacer washers (as in pic) to help prevent breakage. Were they missing?

Mine has the spacer on the bolt between the clamp. I guess I should not tighten them as much?

Torque wrench may be a good investment

I have a torque wrench. Just need to find the specs. A member has offered up their spare tree. Thanks for everyone's help!

Yep, it's a 7mm diameter bolt.
Chain adjusters also use 7mm bolts on most Honda's over 125cc
I often modify top yoke with a 6mm insert to use 6mm bolts on light weight (race modified) CB350's
Every few grams removed from bike makes a difference for us old fat bastards ;D

its been a long time since i have handled seen a cb/cl 33mm clamping upper yoke... but the 33 for the sl350 uses 8mm as do all the honda 35 yokes of that era
on my maikawi i have the 43mm fork pinch bolts reduced to lash with 1/4" military aircraft ti boalts

Had to go measure the bolt
OK, I screwed up. :-[
The shank diameter on 360 is 7mm but thread is 8mm.
Must be the 175/200 and smaller thats 7mm and maybe the very early 360's? I know I had 7mm bolts in one of them and also in the XS650
