I know there's a lot of options for the earlier 750 as far as pistons and such...what's out there for the 16v?

100hp 1981 GS750E...
...lol, how to do it? I've been considering later model engine swaps and, it seems, that's my best bet. I would like to keep the stock lump, though, and no unnatural inductions.

The 750 was a sweet and smooth bike.

Pop an 1100 engine in it, and go see Ray.
It's a really easy swap.Last edited by tkent02; 08-03-2010, 11:02 AM.

Oh yeah...not really complaining about the bike. I know I likely won't get that kind of power out of it. It's just thought. I'm pretty sure to get my goals I'm going to have to stab a GSXR750 block in there.

If I do a "big" motor I'll probably just hurt myself. I've always wanted a B12 block with GSXR1100 cams, pods, and a beefy exhaust. I've never had 100lbs of torque on a bike before.

That's usually my opinion...it's just a matter of power over mass centralization...which do I want more lol
I'd have to do something about the "dinky" 160mm tire in the back with the B12 lump.

I looked into this for a while on a 1981 750. You start running into problems with the clutch after a certain point on HP gains and there isnt a whole lot of affordable options on upgrades. like mentioned above swap it out for a 1100 you will be miles ahead in performance and dollars.

its the rod bearings turning in the rods and making a clacking sound when the piston's hit the head surface.

If the economy ever picks up and every dollar isn't so vital here is where I'll start with my build, 12:1 Cosworths. I already have a set of flatslides and cams. I have an NOS head that will be used for the build. That's where the money comes in.
Everything else will be to complement them.

With the 16v 750 you start with the lubrication system....
Before GSXR's we used to cut the gearboxes off the 750's for speedway TQ's - then mount a big dry sump pump assembly.
You start with a good 70 - 80 lb just off idle and ease all the oil galleries properly for more flow - and still you do rod bearings....
Just bolt in an 1100 - much easier and way more reliable.
And if you want steam engine torque stick with small carbs and cams dialled to suit.

+1 on the 1100 swap
Engine fits great, just the mid motor mounts need to change. My header didnt have to change either. V&H part #'s for their headers are the same from the 750 to the 1100.
The 1100 has a total different personality, its got soo much more low end grunt, and still revs out real nice, and unlike the 750, there are tons of performance parts for it
