1972 Yamaha XS650 project

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:)
 
My usual progression goes something like this, if it’s got a lot of corrosion like this,
View attachment 160073 I start off with a blue Dico wheel and that’ll result in this,

Then progressive wet sand paper from 400 grit up until, 1500 grit gets to this point,

Then hit the buffing wheels,
Some guys like 5T have really nice permanent buffing stations set up. I have a really old Craftsman two wheel bench grinder that pulls double duty as my buffer. It’s not bolted down , I store it in a cabinet and drag it out when needed. My whole buffing set up is just two wheels , a stitched cotton wheel which is very firm that I use a black compound on to make the initial buff, then a soft cotton flap wheel for doing the final buff with, using a white compound.

Then everything gets a hand polish with Blue Magic. Note the fork leg on the left has not been buffed yet.

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?

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'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

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.

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