1980 GS750L total rebuild from ground up to Cafe style

[Sam 78 GS750]

Looking like a great start... I'm curious to see how this progresses.

Yeah you're moving fast! Clearly not your first rodeo.

10 amps on the electrolysis, correct?

Looking forward to your process to clean up the wheels.

I am, once i get started on on a project its hard for me to stop haha

Yes 10amp, wasnt too much rust inside the tank, thought about a 20amp but then thatd just be over kill. Definitely want it to be a slower process. Will be changing out the water here soon and give it another go. Will have a picture of the rod. I really should have taken a before picture of the inside of the tank, but slipped my mind.

Pretty much every painted part will get stripped (like the whells) and then a quick soda blast to ruff'n up for powder coat. Everything will be a Satin Black.

Interesting build. Not a big fan of the “L” models and am curious to see how it turns out.


How does electrolysis compare to using Metal Rescue?

To me the results are pretty equal and get the job done, however metal rescue brings out the shine more of metal. Cost is definitely way different. For electrolysis i spent $6 for baking soda (i already had everything else) and it takes time (24-48 hours).
Metal rescue youd have to buy enough to fill up the tank ($25 for a gallon) the 'L' tank holds 4.8 gallons so $125 right there give or take. And you have to apply heat to whatever you are soaking for it to really work. Just different factors in that way but it all just boils down to the doers preference.

Not too bad with the first run of electrolysis on the inside of gas tank for 24 hours. I just rinsed it out in the bathtub, lots of big flakes of rust poured out. Going to do another 24 hours and then ill dry it out completly, oil the outside, bag it up and itll be ready to powder coat once everything else is prep'd.

[NickyGS750]

Carbs disassembled and cleaned, bagged and tagged. Ready for soda blasting and powder coat. Simple green cleaner goes a long way!

Very interesting to see where the rust deposits; to me it corresponds roughly to where the tank insides are free of gas most of the time, exposed to the atmosphere (and hence, water). Assuming the stuff takes the shortest path.

[roeme]

Wait, these carbs haven't even seen an ultrasonic? They look hella nice.

Was mostly mid and upper section. I agree, as long as there is fuel i think it does its part to prevent rust...i know in the summer months condensation happens above the fuel line. Thats why with every bike i owned i always had the tank full.

Do yourself a favour, drill out the spot welds that hold on the emblems on the fuel tank. I can pretty much guarantee you the rust under there is close to perforation state. I have stripped multiple tanks and also removed them. After blasting there were holes.

It sucks if you don't and the tank leaks after you refinish it.

You are making great time so far!

Nope, not yet... forgot to mention after the soda blast they will get ultrasonic for good measure.
Yup simple green cleaner is the best... for my anyways haha

Yes thats part of the plan, lots to always mention... i appreciate it, lots of fun getting this done!

This sounds like an issue I might be up against soon; so: Spot welds holding emblems? Could you maybe provide pictures on where/what/how?

Edit: not necessarily in this thread, don't want to detract from Nicky's fine work log

I got you!
Circled in red... just drill them out (carefully!) And itll come right off
