With a wealth of information provided by the forum members here I have started down the GT750 rabbit hole of no return. The carbs are in Bazs's very capable hands, (All the way from Las Vegas, USA) and the crank is at Bill Bune's machine shop, (Well know in the states for GT750 crank & machine work.) The engine cases have been cleaned and are the way soon to "Restocycle" here in Tucson AZ USA. These guys are the best at vapor blasting and vintage Japanese motorcycle restoration. Check them out! : https://www.restocycle.com/japanese-mot ... estoration

The new Wiseco piston set has been ordered and the cylinder and heads will be bored, honed and chamfered and will be tuned to OEM compression ratio by the associate machine shop of Restocycle. I have one of Baz's DVD with more to come as help.

The parts list is long and many. I am compiling many vendors worldwide to complete this project. I have nothing but time to do this. This will as they say "Take twice as long and cost 3 times as much as you estimate". When you undertaker such a project you have to realize your "limits of expertise." This is where you guys come in. I will be asking a few noob questions and already you have provide much help. Thanks. Lets get this thing going and may the Motorcycle Gods have pity on my poor soul. :lol:

Update 14 July 2019"

The engine cases have been vapor blasted and on the way back to me. The bike is striped down to the frame. The cylinders have an issue with being bored off center on the #2 jug. I'm having an very high end cylinder shop asses it for me. I may have to find a used cylinder bank. :cry:
Will know more this week. I started the process of re-zincing my OEM fasteners and started with all 32 upper & lower case bolts. Also starting to do some buffing on aluminum parts.
This is where it gets fun. The frame will be off to the powder coaters this week and I will, (As before with other rebuilds) do all the rubber bung placement. This will save countless hours of grinding off powder coat where it should not be. I know the frame was originally painted but I want this bike to last. The new water pump bits showed up. Nice!

Cheers,

Sky


The # 2 jug that was bored off center by two owners ago...Sheesh! (*Not enough meat left on that bone to hone!)

New water pump!

Zinc process....SCIENCE!

Excellent start! You do wonder how that bike ran with the cylinder off centre.. it is very satisfying making bits shiny :D

I have seen these cylinders offset on std bores,
So that means the factory have done the same thing.

Cases back...

The engine cases are back from vapor blasting and they look great! This is a turning point for the restoration. The frame and many other bits are at the powder coat shop and the crank with new seals and one new bearing will be here next week. I have started the process of cataloging the many parts that are coming my way. Also the re-zincing process is going good but slow.

The cases:
