Vacuum advance innards 83 1100

Postby Flyboy6 » Tue Dec 01, 2015 1:27 pm



Doing a prowl through the various parts of the motor while I have it off the bike for some frame repaint. (This time around I got smarter and the bike is an about 80 ziplock baggies and cases with cards identifying the part, and all bolts left in their holes wherever possible. And about 300 photos...)

Noticed a reddish dust on the inside portion of the vaccum advance mechanism. Bike used regularly, working 100% right up to last week, so I'm not suspecting rust due to neglect.

Not really feeling eager to pull apart mechanisms that are working fine. Anyone seen this?

Not on mine either..however I do see this oxidation powder on clean bare metal inside some of the new cars I upfitt...
It appears to simply be rust oxidation on unprotected steel...Personally,I'd clean it with a spray like PB Blaster and then coat it with a light oil spray...NOT WD40 tho...and just enough to protect it till it's assembled.A bit of oil on anything that moves...The spring contact post,vacuum rod connection,bearing set,mechanical advance pivot points and it's collar.
Remember the baseplate rides on a ring of roller bearings.They need to be clean and rust free.If seized,the vacuum advance will not work.You can test this by applying a vacuum to the canister and watching the baseplate rotate a few degrees.
Once assembled,it's out of the dusty elements and moisture.
