    RE: your exhaust headers and pipes, I have used Jet Hot Coatings on a couple of motorcycle exhausts and am very happy with the results. They have 2 places of operation, 1 somewhere in Arizona as the other fellow told you, and 1 in Burlington, North Carolina. They are not cheap by a long shot. I had the 4 headers and crossover for a Kawasaki Concours done close to 10 years ago and it was about $200. That they did not have to sandblast chrome off which is an extra cost. I don't remember what it cost to have my header pipes and collector done for the XJ650 Seca but I am very happy with the result. Shipping costs will be frightening as well. But if you can afford it the results are awesome, quality of work very, very nice. They do a lot of work for top fuel drag racers and such.

    Refurbished the starter today....
    Armature just needed a touch of scotch brite n it was mint, dabbed grease on the bushings, good to go.
    Almost seemed like a waste of time but better to check than regret! Lol! :)

    Dont use anything abrasive to clean commutator rings. An eraser works well. There's a line on each brush that shows its discard length, other than that it's pretty straightforward. If you find oil behind that cover the seal behind the rotor needs replacing

    image.jpeg So, I decided to send my exhaust to Jet Hot. They quoted me $205 US plus shipping but including sandblasting the chrome off. Should be abot $300 said n done, if i ship n pickup from the States. Ill keep posted.
    I welded the tip at the 7" mark, removed the clamp and welded it at the collector, should appear 1 piece when its done.

    Otherwise, i spend 50-80 on paint and a whole day or more prepping, paint twice including two installs and removals to cook paint on, and probably have it rust before summer is over.

    1st, You can clean the pipes up by using some W/D40 and aluminum foil. 2nd: Get rid of that turn out and get a pipe back on it. Unless you are capable of rejetting the carb to match that open pipe, you are loosing hp and opening yourself up to burning out exhaust valves. 3rd, reusing the burned clutch steels will cause the clutch to "chatter". When the plates are "burned", 99/100 times they are warped as well. Did you check/replace the springs? Put a good clutch kit in, (Barnett steels, fibers and 10% over springs) and you only have to do it once.

    Well the pipe is already at Jet-hot getting ceramic coated.
    I bought the bike with pipe and pods 3 years ago, apparently set up right, it runs fine except under 3000 Its a bit touchy if you mash on it, but im sure thats just from lack of vaccuum, it runs fine at any other RPM.
    The discs with hot spots are straight, not warped and the spring free length was in spec, it went back in.
    Fibers are EBC, $75CAN for all instead of $26 each from barnett.

    Btw, clutch never chattered, it slipped a bit in the top of second, or if you downshifted hard into 3rd to pass.
    The fibers were completly worn out, and burnt, im sure it will be fine now.

    For anyone wondering it appears to be jetted up for the pipe and pods, as i expected, it runs too nice.

    Ok, so im planning to drag race my bike this summer :)
    I have to install a tether cord aka lanyard ignition stop. Where is the easiest place to tap into the kill wire, without cutting into the harness? Tank is off but i assume headlight bucket connectors?
    And to be sure, its the black with white tracer, correct?
    Thanks!
