79Gs400 Total Rebuild
Hey guys,
I’ve got a couple of questions about a 79 gs400 rebuild that I have started:
-is using a vapour degreaser to clean a completely disassembled engine prior to rebuild a bad idea?
-any recommendations for clear coating the engine? I’d rather do that than paint it if I can
-any recommendations for buying braided lines? In Canada? Elsewhere?
-any important engine (or general) rebuild no-gos?
I am new here, but have recently picked up a 79 gs400 and a 79 gs425 for cheap, neither of which are anywhere near running atm. The 400 frame is registered out of province, and I have no papers for it, but has a solid looking engine that I plan to completely strip, clean, rebuild then plug into the 425 frame (better shape and also registered here in BC). I will also have to rebuild the carbs, airbox, brakes, and probably the harness. I was thinking about cutting the pipes and frame, adding pods, and rejetting the carbs, but I am going to hold off at least until it is on the road stock-ish —I know that this might not be a super popular choice, but a this point I was saving these bikes from going to the scrapyard so I thought I'd try it out down the road.
I have experience working on crappy old pickups and an old honda bike, but this will definitely be my biggest engine project to date, so any advice (engine or general rebuild) is welcomed. I will be doing pretty much everything at home with my trusty socket set, but have access to some other tools and machines at work.
The 400 is now pretty take apart, and as a next step I am looking at how I will clean the engine. Any tips? Engine is out but still whole right now, as I wanted to come up with a plan before splitting it open. Ideally I will clean it inside and out, because although it turns over I have no real idea of what its guts look like. I could get access to glass bead (probably a bad idea on aluminum), plastic media blasting, a vapour degreaser, or just plain old sweat and scotchbrite. Any and all wisdom is appreciated.
Note that I plan to rebuild the engine mostly following a Clymer manual.
I plan to either clean the gas tank electrolytically, or also using the plastic media and degreaser.
I posted here because I have questions of all types, and am just starting out —I will ask some specific questions in other threads. Will keep you guys updated with pics.
Thanks
