    Got her buttoned back up and she started great! Just in time for the first day of Spring. Man, these new Keihan SS headers are mighty nice. I'll probably be posting again soon, seeking advice for a compression and leak down test (yes, I know this should have been done at the very beginning).

    Sweet! I just polished out my stainless headers. heard if you get any oil on them, including fingerprints, they get brown and nasty. Dunno how true it is but it's enough work to restore them I'm gonna be careful.

    Hint: see where the front brake cable touches the front fender? it wears through the paint right there. A strip of the clear stick on stuff used on tanks under tank bags is good preventative medicine. Redo it every so often. I had my /5 for about 20 years, 19.5 years longer than that particular girlfriend. Just selling off the last of the parts.

    Thanks Plaka, appreciate all the advice. I rubbed down the SS headers with isopropyl rubbing alcohol to get rid of any oily fingerprints before I started the bike last night. The SS headers should turn slightly gold, correct? Anything else I should know about proper care of SS headers?

    Luster Lace was recently reintroduced to the Oz market and it worked really well on the Staintune system on my G/S.

    The long wide strips worked the best, and the exhaust has taken a nice Titanium like light bronze sheen which has lasted well and has brought a few favorable comments. Much better than anything else I have tried, including Autosol , Muguiars and Mothers.

    But Meguiars Black trim detailer has been reformulated and it is now the best I have found.

    Staintune have also started selling their OEM polish on Oz Ebay but I haven't tried it yet.
    Maybe when the Luster lace runs out-----.

    Just use alloy wheel cleaner, the acid removes the brown sheen, then polish with your polish of choice

    the headers turned almost immediately light brown after starting the bike. That's normal, right? Maybe light brown is too strong, a very, very light golden.

    Normal. My Staintune mufflers were about brown before a polished a bunch of scratches out after my last crash but then again my BMW headers are blue and purple and yellow clear to the plenum.

    The best thing to reduce headers from changing color is getting out of the choke ASAP.

    Yes, that is how your stainless steel headers will look. They will get a little spotted or something so riders clean them to get them back to even again.

    Chrome headers turn blue.

    I have a cheap set of something else. Brand new they immediately turned to rust. :lol3

    Those Luftmeiser two into ones were good pipes IMO. A customer of ours back in the day bought a R90S from us brand new and for some reason that thing was a runner right out of the box. It was by far the best running 90S we ever sold not that we sold THAT many of them but . . . . It ran better yet with a Luftmeiser two into one on it.

    BBQ paint on the inside of new chrome headers will help to reduce blueing, this is what I did when I fitted new 40mm chrome pipes to my R90s replica.

    Only stuff I know is what I have been reading here and what I have been going through re-habbing mine. They blue close to the head then straw colored further down. You can keep buffing it off but I kinda like the look-o'-power. Mine got straw colored all the way to the muffler. I suspect just keeping them real clean will go farthest to avoid corrosion, will have to see. Not hard to rehab them, you don't remove enough metal to matter. Mine were really bad and looked like hell. Had them on about 3 years. I suppose I can deal with touching them up annually with the conditioning disks and a buffing wheel.

    It's like exhaust wrap, but on the inside!
