    I'm not fussy like these guys but jump from dico to black buff on a sisal wheel then green or blue buff on cotton call it done. Horsepower matters if you are doing a lot of buffing but a small motor will do the job with patience. (or so I've heard:rolleyes:)

    I just kept seeing those buffing wheels getting black and didn't know if at a point they would get gunked up and unusable guess that's not the case
    Thanks

    the wheels do plug up, why you need a wheel rake.

    Eye and breathing protection needed when buffing!

    Pop Quiz! I needed to replace the back brake electrical relay. It was missing when I bought bike. As I install new relay I see four possible wire connection options. Can't tell you why. In any event the question is... which wires to attach the new relay to. See attached pic. The two brown wires near top of pic? or the brown wire and green/yellow wire near bottom of the pic? Special prize for the correct answer. Thanks, Sean

    I'm pretty sure these are the ones for the rear brake lit switch.

    These 2 are most likely for the turn signal flasher.

    There is no "back brake electrical relay" what're you putting in, rear brake pedal switch?

    Keep it up Bob, and you'll be up for another "RobinC Seal of Approval Award". I don't think MamaYama made them so shiny! If I can get "The Basketcase" to the "not ugly" stage, I'll be happy.

    You say tomato I say tomoto. Yes, it is the "rear brake pedal switch". It appears from the attached diagram the switch is wired into the brown and green/yellow wires. Do you conquer?

    I don't conquer but am happy to concur, ;)
    Yes like in GLJ's pic above, that is correct.

    Thanks Gary. I've been sick for the past week, so I'm not thinking clearly nor spelling correctly. Sean

    I've been enjoying the project and can see some progress. On to the carburetors. I see Mikes XS has a carburetor kit which looks pretty good. Any suggestions or do's or don'ts? Thanks, Sean

    I think of MikesXS as the XS650's JC Whitney.

    Read the carb rebuilding threads in the tech section.
    Replace the throttle shaft seals.
    I've used the carb kit from Mikes with no problems on my XS2. I did not use the needle that came with the kit. Also used Cruzinimage floats. Most people here will say that genuine Mikuni is the best parts to use and I don't disagree with them. I had my reasons to use what I did and the results have been OK.

    I may assume that's a good thing, although I know some people who don't think much of J C Whitney.

    Thanks for the advice. I am not familiar with the "the throttle shaft seals", where are they? Thanks, Sean
