This first happened a year or two ago, and it's happened every once in a while since, but it's started happening MUCH more often lately...

When I'm going to pass, downshift a gear or two, let the clutch out, romp the throttle, and the engine RPM's shoot up, but the tire don't spin any faster... Let off on the clutch and ease up and we're fine...

Assuming this means it's time for a new clutch...

Ugh.

So, if my assumption is correct, anyone know what I'm looking at? Is this a "Wrench Party" do-able job? Or should I start lining up a mechanic? (Tearing into the tranny is not something I have ANY interest in doing solo!) How much would the parts run?

I know I could google some of this, but I'd rather ask the wisdom of others who mighta been there before me then just randomly googling...

Thank you!

Mobil 1 15w50, and I always check to make sure it doesn't have the friction modifiers or whatever it's called on the label...

If your Valkyrie is high mileage, it may be signalling new clutch. Mobil 1 15-50 is a well used oil amongst some riders. When you install a new clutch, it might help to let up on the throttle romping.
My .01 worth.

It's actually not a bad job.  Disco and I did mine a year ago.

It's a wrench-party candidate and I definitely don't think you should pay a dealer for the work.  I believe we've got the means to compress the stack and replace the discs ourselves now, too.

I did the job solo.  Check out the pics from Lady Draco's post, and it'll help you understand what all it entails.  Nothing you can't do yourself with a little help from your friends  cooldude

Yeah, 105,000 miles, and been using the Mobil 1 15-50 since about 500 when I did my first oil change after break in.

And yeah, I should let up on the throttle romping, but, well... That's why I got a 6 cylinder motorcycle in the first place! Hehehe

Thanks ya'll... Once things get colder looks like I might hafta dig deeper into this and see if I can bribe my way into a wrench party for this one...

Seen this a lot, on several bikes, over lots 'O miles.

Change to Castroil Diesel engine oil. 10/40 and see what it does. I'm guessing (I'll bet you a beer) it'll quit. Change at 5000 mile intervals.

I stay out of the oil debates, simply because it's like debating the election of a new religion or something, but I've slogged a LOT of bikes. You cannot beat the Castroil Diesel engine oil in a wet clutch situation.
And don't let up on the throttle romping. That's what they are *made* for! Smiley
