best upper triple tree for a 350f with 750 forks (new to forums)
« on: December 05, 2015, 03:56:30 PM »
So I bought a Frankenstein 350F with a 400F engine and 750K0 or K1 front end and ton of spare parts for $600 running and registered a couple months ago. It was a bit rough, but I'm going through it piece by piece and I'm making it into a cafe racer, I finished restoring and painting the frame, almost finished with the engine. I'll have to shorten the forks a few inches.

The problem is the unicorn style upper triple tree is shot and replacements are going for a pretty penny on ebay, even then it would most likely break again as the K0/K1 fork clamps are pretty weak. The bottom triple tree seems fine, but its pretty rusty, I'll have to hit it with the sandblaster. What other bikes can I get top triple tree from that would match up with the 750 forks and K0 stem? I'll be getting new bearings from AllBalls. I'm not sure about the stem length, it seemed like it was fine before I started tearing it down.

Similar questions have most likely been posted, so if giving me a link if thats easier than typing it out, I tried looking before posting but I'm not getting anywhere with my search.

Any early model K top clamp will fit the forks. The issue is the length of the stem from a 750 into your 350. I'll wager that's it's at least .750 too long.

"Of all tyrannies, a tyranny sincerely exercised for the good of it's victim may be the most oppressive. It may be better to live under robber barons than under omnipotent moral busybodies. The robber baron's cruelty may sometimes sleep, his cupidity may at some point be satiated, but those who torment us for our own good will torment us without end for they do so with the approval of their own conscience." - C.S. Lewis
