Yeah they were really gross for sure. The second carb is about ready to be assembled and stashed away so I guess cleaning out the tank is next. Oh joy...Wow, those carbs were really gross.
You should check with the city/county you live in but many cities will have some sort of pop-up free hazmat drop off site every few months. I bring them everything from old solvent, to old paint and used cooking oil, some places will even let you drop off a couple tires.
Very true. Looks like I'm going to switch to @Hurco550's original R90 caliper until everything is sorted out w/ the thing. At least I won't scare myself trying it out going up and down the alley behind the house. Once I get it sorted out I'll look at big brakes.More brakes is more better
I'll do that, thanx!Many swirl a little 2 stroke oil in the clean tank to prevent flash rust.
Thanx, buddy! It reassures me that there's lots of good lurking under all that dirt and old gasoline! I don't expect showroom perfect from a bike that's nearly 50 years old, but I'd be very pleased if I don't have to do much painting to have it look like a healthy survivor. Like many (most?) of these w/ the master cylinder under the tank the frame tube there is paintless and rusted. I'll clean that up, mask it off, and spritz it as necessary and there may be a few other spots, but mostly it's looking like some patient clean and shine work will make it presentable. I am thinking, though, that the spokes will probably have to be replaced, I think that's too many spokes to sandblast and repaint. I'm considering black spokes, what do you think? The rims on these aren't shiny nor are the hubs so I think black would look better than chrome or stainless.Looks phenomenal
There's definitely a sweetheart of a bike under all that grime. Also, I 100% say we re lace those wheels with fresh spokes. Could be this winter after you've ridden it a bit. The wheels and hubs maybe send out to @irk miller for vapor honing and you'll have a real nice set of hoops.Thanx, buddy!

Thanx! Yeah, not sure what I'll do w/ the rest that's in there. Problem is if you look at 100 different internet comments about it you get 100 different sure fire ways to fix it.Nice save on that tank looks mint! The best way to get the tank liners out is with paint stripper. Just went through that nightmare with my GSXR. obviously the chances your paint will be destroyed are high, so its a last ditch effort.
Appreciate the input/opinion!My .02 on the spokes - painted nearly any color can look good as long as they are painted separate and assembled, and the nipple is not painted.
AND looking at everything else I think that the front fender has the potential to clean up as well. The rear fender looks like it will be good but not fantastic and the side covers look almost like new. So, all in all, that part should be great. The Wixom bags are about like the rear fender; good but not fantastic and the S fairing is good except for a chip right next to the headlight opening. I'm not sure whether to attempt to match and touch it up or to just leave it as character/patina.Looks phenomenal
Rust is non-magnetic to paramagnetic, so it will not stick to a magnet like sheet metal.I just got done cleaning the tank. It sat w/ the cleaner stuff in it over night and I'm confident that gasoline and acetone residue are gone. More cleaner went in w/ a hunk of chain and then swish and shake, swish and shake. Finally I rinsed w/ lots and lots of water, both w/ the chain and then w/o. The last bunch of water came out very nearly clear. Looking inside I don't see rust but it does look like red liner BMW put in at the factory has largely chipped up and come out. I'll do a search to see if there are good instructions on how to get rid of what's left.
Then I left the old shop hair dryer run down into the tank on high air/low temp for over an hour. The dryer nozzle fills the neck and there was a good flow out both bungs. (I'll go out in a bit and put more air through it for a while just to make sure.)

Here's a pix of much of the sediment that came out of the tank. It looks red like rust could, but I put a magnet down into it in several places and no metal particles stuck to it so I'm sure this is all liner bits and, perhaps some amount of dirt collected since 1975.

For now, once I'm sure it's dry inside I'll close the cap and put corks back into the bungs and hope it doesn't flash rust.
