I have also thought of putting on FCR39's but the TM-36 run fine and I'm enjoying the bike too much to dismantle everything just for the FCRs. I also was fighting to get the clutch piston and pressure plate to line up properly, and believed to have resolved the issue. Can't go without a little drama on this old thing

Thanks heaps for the base line data. Really appreciate it. Glad they run well.

You're welcome! Hopefully they work out well for your case, too!

I got hold of two used slant bodied horizontal FCR39's with choke (enrichment) knobs designed for dirt bikes. Powerbarn provided a 2 into 1 throttle kit and Niche Cycle supplied manifold boots. After some fiddling they work well (on an M750 modified to dual sport). MikuniOz can sell everything to build a TM kit similar to your set up and I would recommend that as an easier cost effective kit for belt drives. Used FCRs can cost more than a complete kit for the TM 36/38. I'll do the TMs as a budget option if not requiring an accelerator pump. Thanks again for sharing.

Roger,

Perfectly executed, kind of restomod.
Love the black air cooled desmodue engines (with the alloy belt covers).
What did you do with the exhaust manifolds/pipes, is that paint or ceramic coating?

Have lots of fun with it!

Thanks, Frank! I inherited the bike pretty much how it looked I just brought the internals back to life and up to date. The header and pipes were painted, I think. My contributions were mainly the carburetor tuning, ignition coils, fuel filter, and chain/sprockets.

I also have a new shock on the way to bring up the rear end to quicken steering and reduce the shallow lean angle

Thank you!

New shock installed. The bike now handles like a real motorcycle

The shock looks great. What type is it? Also what length did you go for? Is this standard. Inquiring minds need to know (well I need to know for future options on mine!

Keith,

The shock is from Cogent Dynamics Engineering. It is 13.375 in (340 mm) long at the shortest and can be adjusted out quite a ways. The original carb SS shock was 13 in (330 mm), which had the bike steering quite slow in comparison. The SSie shock at 13.25 in (336 mm), offered a good length for many carb SS riders for quicker steering. Hopefully this helps!

Thanks Roger, that’s very informative. Hopefully I will start getting my 750 sport sorted this year!
Best regards
Keith MM

You're welcome, Keith! Happy to help and best of luck on getting your 750 running well

Put these on.
