    Powdercoating predicament

    I know this topic has almost been beat around as much as gutterballs nutsack but I had a couple of questions that I couldn't come up with while I was searching. I just pulled all the shit off of my bike to get powder coated and I had some LSL frame sliders and an MSR shifter that I am worried about powder coating. My main concern with the LSL's was would it be best to powder coat them or just rattle can paint them? My preference would be to have them powder coated but I didn't know if the oven temperatures would temper/anneal the aluminum to the point that it would soften it or weaken it. I wouldn't want that if I actually had to use the sliders. Also, the MSR shifter that I am about to put on I wanted to have it powder coated too but the toe part on the end that hinges doesn't have a clip to remove the pin in it. I know I could drill it out and pop it off but I don't know what to replace it with. Here is a pic of the shifter installed on harley's bike to get a good idea of what it looks like installed.



    Here are the up close shots of the shifter and slider hardware

    Don't know what grade the LSL's are made from, but common alum grades(6061,2024,7075) anneal at 750F +. Coating is usually done around 400F. As for the shifter, the pin may just be a press fit, if so you should be able to drive it out. Unless its been peened over on the side opp the head(2nd pic). Can't really tell from the pic.

    on the annealing of the aluminum, no issues there at all. It takes at least 650 F (usually a bit more) to get sheet alloys to bend easily and, as stated by Lindy, powder coat cures well below that.

    As far as the pin in the shifter, I would drill it out and find a suitable button-head capscrew and thin nut to put it all back together. Put the nut on the lower side as viewed on the bike and should blend right in. The likely bitch of the whole operation will be getting the spring back in properly.

    Yes they do. Great mod for under $25. If memory serves the shifter is for a '96-03 Yamaha YZ 80. It's posted a couple places around the forums with the actual MSR part number.

    Re: Powdercoating predicament

    Which part of the shifter do you not want powdercoated? I used to manage a powder coat plant and we did a lot of stuff like this, masking off specific parts, places. Other information is totally correct, there's no negative effects on the aluminium through the curing process, even at the hottest curing point. I'd hesitate to drill anything out if I didn't have to.

    Sorry for the hijack but the experts seem to be here.

    Can I get my forged aluminum wheels that are anodized, powdercoated without any problems?

    Re: Powdercoating predicament

    Why would ya want to powdercoat 'em once they're anodised?
    IMHO anodising is the best protection against corrosion you can use for aluminium.
    And that nice gold colour.......
