78e, acceptable stock ignition ?

[member28833]

Hello XS community , Recent inspirations by this sites positive attitudes ! have me prioritising my own XSe a little higher on the "to do" list.
Previously after failing to diagnose and repair my own bikes electrical faults, I parked it dry and moved on to other fun things
We'll, it's mid November, so there is no better time to clear the path in the garage to the back wall bike right ?
Here is my newest electrical concern !
Trying to keep my bike stock. My newly acquired rotor does measure 5+ ohms. Yes !
Looking at these hair line cracks in the "urethane" protective coating I am wondering. Should attempts be made to seal these cracks ? With what ? Are these cracks commonly found ? Will temperature change affect these cracks ?
Should these cracks just be left as they are ?
It would be great to hear a few opinions from you all.. Thanks -R

Well it should be fine for local rides at least, run it while you do the wake up get a voltmeter on it... [URL="http://www.xs650.com/threads/stella-1977d-survivor-back-on-the-road.47329/page-42#post-557124"]Stella - 1977D survivor, back on the road.[/URL]
(always a good idea). Any blackened or missing varnish is prolly not a good sign.

You can seal it with this stuff.....

I got it from Amazon. Not sure where else you can get.
It will seal against moisture... but keep in mind that rotor is about 40yrs. old. Ain't much life left in it.

"Vernis Isolant Rouge", Yup that looks like great stuff !
But JimD54 what do you mean "That rotor is 40 yrs old. Ain't much life left in it" ?
The responses so far seem like there is hope, thanks
fyi, I did previously purchase a Chinese made rotor. It was so badly manufactured that I couldn't find it in me to bolt it on.. -R

I mean that at 40yrs. it's pretty much at the end of it's life. You got 5 ohms... so it should work just fine, which is great, but nothing lasts forever. If you search around this forum you'll find that the average life span for that rotor..... is about 40yrs.

Ya, I get it. Hey Jim, I remember when you were rewinding. If or when that were an option, my stock dead donor rotor is a very good candidate. Very good condition. Other than that It Does Not Work Lol !

Welcome to the zoo!

Yeah... excuse my manners.... welcome.
