Overheated bike and fried clutch
Hook#3287:
My guess is the dampener plate is totally toast and just spinning cause all rivets failed.
Also, can't remember very many overheating's that the rad cap blew off. :???:
Would overheating cause a rivet fail or is it just a coincidence?
Removing the rear engine cover is not difficult and maybe you'll see rivet pieces in the bottom of the clutch area.
Hook#3287:
Did a little research and a symptom of a failed dampener is a slipping clutch, although I can't remember that symptom ever being stated about the Valks clutch.
Checking the service manual, a cause of a clutch slip includes a bad or compromised clutch spring, but that seems few and far between also, if at all.
So, is the clutch issue related to the overheating or coincidence?
How could overheating cause it?
I would think the boil temp of the Dot4 is to high to be affected by engine overheat, but maybe, or maybe a rubber seal was/is comprised and introduced air in the system.
But it does seem the system could be air locked.
Could overheated oil cause damage to the clutch?
Looking forward to the resolution of this issue.
Another question is, what's the pinion and cup look like? :roll:

First year Valkyrie clutches will rarely suffer from loose rivets. Given the problem came with overheating I'd look into the hydraulics first. You may have a 30-year-old bike still using the factory brake fluid.
Not trying to be a jerk. Just sayin' that rivets gave way on my 97 clutch at the 60K mile mark.
All depends on how hard you beat it I guess.

I haven't looked at it recently, but I did the rear end service just a couple months ago and it looked fine.
I'm going to pull the cover this weekend and see what I see. I triple checked the slave cylinder and I noticed that when I slide the push rod that actuates the clutch back into it's place, there's a very slight "gritty" noise. Another indication that the clutch is in trouble.

CactusValk, good luck :cooldude:
It's been over 20 years since I've removed a rear case cover, but I think getting the bike high enough to get under it is important.
