Custom GT750 Help needed

New member here, but not a complete cherry.
Had a GT550 when I was a teenager back in the mid 80's, but mom sold it with the rest of my toys when I left for the Army in 1985.
I have a modest collection of Kaw Z1's and KZ's from the 70's, but always wanted another GT550 to trick out. So I picked up a GT550 from a CL ad I seen the other day.
A GT750 parts bike came with the deal, so I thought I'd build something custom with the GT750 and leave the GT550 stock.
I seen a couple builds the members here have made that I like.
So now to my question. What forks, triple trees and swingarms fit the GT750 frame?????
Any help I could get would be great!!!! Pictures of ideas are welcome also.
Thanks in advance
From the new guy

Stock vs. GS-series forks on a GT750:
The gray GT750 has forks, triple tree & brakes from a Suzuki GS1100GK.
The forks are a good bit longer than stock.
Subsequent to taking this pic, I used a Progressive Suspension lowering kit to get the correct fork length & sag on the GS1100GK forks.

jabcb,
Thanks for the pic.
I like those GS1100GK parts you installed. They look a lot better than stock to me and I bet the braking is much better also. I remember trying to get my GT550 to stop years ago. The brakes really sucked. I'm no stranger to getting the correct ride height. I had issues with my 1974 Z1 street fighter build and had to have fork extensions made to get the ride height correct.
My 900 Enduro build was quite easy.
I just installed 82 KZ Police forks and wheels with a GS11OO swingarm. I found a set of 365mm eye to clevis progressive shocks to level it out. It worked perfect.
I have also been taking a good look at what Suzukidave has done. He installed a GT750 motor in a GSXR 750 frame, but the build thread was lost.

Well, If you can give me a little leg up on what I might be getting into installing a GT750 motor in a GSXR I might give it a try. That's if I can find a reasonably priced donor?
I started this thread for ideas and haven't made my mind up yet, but If I can shoehorn one of these motors in a blown up GSXR, it might be the cheapest route.
I have been looking at parts prices for this build and it could get real expensive real fast going to ebay.

I love your quote. "the older i get the faster i was".
If that isn't the truth! lol
I'll remember that every time I'm in my shop from now on and look back at my old school drag bike.

Yeah .. i will not lie . it can get expensive , i mean not like 5~6K expensive but enough . Just rebuilding a fairly stock engine could run 1000~1500$ depending on what needs done and then the cost of the donor bike ( i spent $1200 + cost of title transfer) so if you stay with the stock frame those $$$$ could be rolled into upgrades .

If you like drag bikes .. maybe a drag GT750 would interest you ? List member Kevin Hutchinson has built him up a record holding GT750 and he is always looking for new guys to join in to kink some Kawasaki H2 butt

Yes, I thought of that, but by the time I mod triple trees and buy a swingarm, rims, tires, forks, and all the the other things needed. I think I'd be money ahead sticking the motor in a complete bike with a blown motor. I could have bought a complete GSXR last summer with a bad motor for $700
I couldn't buy the parts I need for the stock frame that cheap. (I need a lot of parts)
I was also invited to go meet Bill Wirkes a couple of weeks ago. Maybe he could give me a hand with the expansion chamber mufflers I'll need made? Looks like a custom job and I've never made any before.

Oh no. lol
I don't need another drag bike. I think I have seen a video of his bike though?
Don't they call him the "Hatchet"?
I have a 250HP ZRX turbo bike that scares the hell out of me.
I am too damn old for it and when it warms up, it's going to auction before it kills me.

I like that bike mockup!
I looked at a video of a bike being made like that, but wasn't a fan of the huge tank and the tail way up in the air. (That's just me though).
This is the video I'm talking about.
