The Pre Kat, which was air/oil cooled makes for an easier swap, as does a 600 Katana engine.

 The 750 engine I'm using is air/oil cooled. It has the same dimensions as the 600 Katana engine. I am using a set of carbs from an earlier model for ease of tuning.

 And now I have shock mounts. Ended up buying a second set of clevis mounts, turning one set from a I_I shape to an L shape, then boxing it in. Both sets of clevis' were welded together and then welded/boxed onto the swingarm.

 Now...on to the engine fitment!

So, this happened....





 Found a local guy that's an engineer and has some gab skills. He's doing all of this from his home garage. I couldn't be happier. He truly "gets" what I'm trying to accomplish and is doing quick, neat work. Today was just a "touch base and check on progress" kind of day and I'm thrilled.

 The rear upper mount is very nice and it, along with the lower RH mount, will be removable and make getting the engine in and out very easy.

The front mounts are the stock Katana mounts that he cut/modified and welded. The rubber dampener inserts were rather worn, so he made these aluminum spacers.




 He wasn't quite happy with that though, so he made theses Delrin spacers.

 I think it's gonna look really cool...and function great, too. He's still working on two of the lower middle engine mounts. We also checked header fitment and discussed the oil cooler mounting today.
 He's already checked chain alignment with a straight edge. Today, we ran the chain across the sprockets (I'm gonna need a longer chain) and it clears the frame, but is tight. The upper run can probably be cured with an acetylene torch and a ball peen hammer. The lower run may require some minor clearancing around the foot peg mount bosses. Switching to a 520 chain really helped.
 I'm also going to take the muffler with me next time I go and discuss a rear hanger for it.
 Oh, and he's going to work on the steering stop to prevent the larger forks from hitting the tank.

 Picked up the GS/Kat project from the welder about a week ago. I'm really happy with the quality of his work and his solution to some of the things we faced. It helps when your welder is an engineer, too!

 When I got it home I couldn't help but slap on some bodywork and see what it might look like!

 Been kicking around ideas for the gauges/dash. I have these early GSX-R 750 clocks, and I found a speedo drive that fits my wheel, but they're incomplete. I'd have to come up with some idiot lights and some sort of pod/dash/flyscreen to finish them off.
 I like the idea of old school analog gauges. But it might be easier to go with something modern. There's also the possibility of fitting a dash from a Bandit 1200 or similar.
 This is something I still need to figure out.
