GT750 winter project

[AFRetired]

Two days before Barbers Vintage Festival, I bought a 74 GT750 off craigslist with a locked motor. At Barbers I bought another 74, supposedily with bad crank seal(s). Hopefully I can make one good bike out of two bad ones. It will be my first attempt at a GT750, I'm sure I will have to make good use of all the resources here!

The Barber's bike looks nice, just do a crank seal job on it.

Ha! You make a seal job sound so simple!

[ConnerVT]

It is simple:

1. Disassemble engine.
2. Send crank off for rebuild
3. Reassemble engine.

Three steps. How easy is that?

First step is to try and get this thing running. Fuel sys first. I derusted the tank with 36 hrs of 4 gal of vinegar. Turned out pretty well. Only had one petcock between my two bikes, and it was buggered up. Found a rebuildable one on here (Thanks Pearljam!) threw it in the ultrasonic and only need one gasket to finish. Will start on carb cleaning soon, then we'll see if it will run.

Anybody want a GT750 sissybar/luggage rack?

Glad I could help. And thanks to you. I started my own 750 restoration a few weeks ago. To do it right and to do it complete is a lot of work for one guy. But, I have been amazed in the transformation of certain parts with simply cleaning, removing rust, sanding and polishing them. I had parts that were so nasty that they were hardly visible under layers of crud. After a lot of time and determination they now look nearly new. These old bikes are worth every effort that someone is willing to put into them. Good luck on yours. I like to hear stories of people's finds of these old bikes and how much they payed for them
If you don't mind sharing?

I paid $600 for the one with the faded paint and a locked engine. $1100 for the one with good? paint and supposed bad crank seals. 15000 and 3500 miles respectivly.

Pretty good deal. You should easily be able to make back at least several hundred in parts after you're done. I would have went for those deals. If it were me, I'd get the crank done on the one bike. Regardless it being accurate in needing them. Because of its age, supposed problem and longevity you will receive as a result. Makes an attractive selling point with receipt. It costs around 350 dollars, parts included.

I probably will go ahead and have the crank done. Just want to find the best value on it. I have heard about Bill Bune, but have also heard of a guy in Nashville who is good too. Would make a good excuse to visit my oldest son, who lives in Nashville.
