I got the hub apart! It wasn't too bad. The bearings feel pretty good and I'm thinking that I might just paint the hubs myself and leave the bearings in. I don't think the hubs really need powdercoating. Was wondering if anyone here has experience painting spokes? I want to have a completely black wheelset, and am thinking that I'll wire brush the spokes & nipples and just rattle can them, then get the rims powdercoated since they are chrome plated and cheap paint is going to want to chip on that. ALSO! it's the last day to get in on a t-shirt if you are feeling it. After the order closes, there won't be another chance to get one. I think it ends around 8 CST tonight!

I painted the rims and hubs on my 360 and have had minimal road chipping. Most was from re-lacing the wheels anyways.

If you have the hubs apart you might as just well do bearings. You aren't saving anything by not doing them. They are cheap and pretty easy to do, and added security knowing they are new sealed bearings.

Was wondering about that. Will probably just go ahead and do it. Thanks for the nudge

If you're going to paint the spokes I would recommend scuffing them up with some 220 grit after you get them clean with a wire wheel. The wire will leave them too smooth for the paint to really grab on to. I haven't used it on bikes, but I've heard that people have really good luck with appliance epoxy on wheels. You can get it at any hardware store. I know that it coats nice and sets up very strong.

Whelp, that was a bit of a break from normal posting. After getting my cylinders last year I kind of hit a wall. Realized I needed to, at a minimum hone them, but thought I should probably get them machined. Life and work and all that jazz and a week turned into a month... yadda, yadda, yadda. We've all read this story before. Well after a walkthrough of the amazing Revival shop in East Austin, I got a name to call for machine help. I dropped my parts off and am getting a full refresh with some help. We are doing a slight bore with new pistons, I needed a couple valve guides replaced and vapor blasting everything. So stoked! While all that's going on I sold my house and have about a month to try to get as much done as I can, so I have a fire lit. I need new rubber and was thinking about going with something a little wider, I also like the look of matched size front and rear tires. I've read a bit here about tire sizes, but I can't quite figure out what to do. I was thinking that the cheap way to go is to find another steel 18" rim to lace up to the front hub and put the widest thing I can safely fun on them. Anyone here have recommendations? I measured my stock rims at about 2.75" width front and rear. Alternately, I may be able to swing some aluminum rims from Buchanan, but am totally unsure what width to go for to keep clearances ok, but to give me the look I want. Thoughts?

So the gas tank on this thing is pretty bad. I tried soaking it in vinegar and it didn't make any difference. I was thinking about just finding another tank, but the 350 four tanks that I like are pretty pricey. So I figured, why not slice this thing open and give it a complete scrub from the inside, bang the dents out and braze it back together? I figure all it's going to cost me is some sweat and time. So that's what I did. Started off by trying out a hacksaw blade, but that was painfully slow. So a I pushed my Dremel to the limit and used about 4 reenforced cut wheels. I was a little nervous about abrasive cutting into a tank, but I gave it a good flush with water and went to town.

Here's the inside:

It looked like there might have been a weak attempt to seal this thing, there was some kind of layer of gunk in it that accumulated along the bottom 1/3 of the tank. As I wire wheeled through it, it smelled kind of plastic-y.

And a couple hours later I have a clean tunnel and shell. I couldn't really get into the seam as well as I'd like, so I might need to spend a bit more time on some problem areas, but this is a good start.

Someone probably used KREEM on it at some point.  Stuff should be outlawed.

Lots of good protective coatings on the market like POR-15 or RED KOTE.  KREEM IS KRAP.
"Quality . . . you know what it is, yet you don't know what it is. But that's self-contradictory. But some things are better than others, that is, they have more quality. But when you try to say what the quality is, apart from the things that have it, it all goes poof! There's nothing to talk about. But if you can't say what Quality is, how do you know what it is, or how do you know that it even exists? If no one knows what it is, then for all practical purposes it doesn't exist at all. But for all practical purposes it really does exist."
