Suzuki TR750 engine


I've owned a number of GT750s over the years, enjoyed them but I always wanted to make it a bit more sporty. It's a big wide heavy lump. It would be nice to make a replica of the TR750, so I've been collecting pictures of the engine and components.
 Although the TR used a different cylinder casting than the stock bike, improvements in porting can still be made. The crankshaft was stock until the last models, I believe. The big issues would be the dry clutch and the 6 speed transmission. That setup is not easily replicated. I tried a GSXR gearset hoping it might be useable, but nope, too wide. 
 Anyways, I'll use this post as a repository for any info and pictures I can glean from old magazines and wherever else.
As a bonus, the pic below is a who's who or Suzuki riders.

GSXR gear cluster won't fit.

  1. I recognize Gary and Barry, and is the guy second from right Ron Haslam? Who are those guys, please?

    A shadowy figure in NZ presents a photo of his GT750 6-speed conversion here --



    -- but I see no text description of it on his site. He also put up a fairly unhelpful 20-second YouTube video:



    I hope your Comments box -- I mean the one I'm typing in right now -- agrees to show the links. Google brings up some woofing about using a trans from one of the smaller GSes as well, but I didn't read them. Since I'm a busy man and all.

    Thanks as always for the Show & Tell. Please build a GT/TR street racer and tell us all about it.

  4. Gary Nixon, Barry Sheene, Cliff Carr, Ken Araoka, Paul Smart. It appears the transmission parts for a dry clutch conversion are available, it just takes money. https://www.ebay.com/itm/384415954271
    It seems I'm not the only guy wanting to make one.
