Don't think It's the coffee grinder...

In reading the description of the coffee grinder, it sounds like it should be mostly just sound, or should there be a bit of a lurching involved?

When cold and not properly prepped (I.E. squeezing the clutch lever multiple times after allowing the bike to warm up for a few minutes) my bike tends to lurch forward accompanied by a "coffee grinding" noise when the clutch is eased out.

I have a decent amount of adjustability left, so I'm not sure the clutch needs replaced - but it's pretty annoying when it's wet and slippery out....

Well, maybe it is not the miles , but the age. I'd put in new clutch plates, spacers and springs.

(even if you admit it happens only when you don't let the bike warm up properly)

Kinda figured the same...

Are the EBC Kevlar the current favorite clutch?

I kinda have a feeling I've been getting slight slippage as well (just enough to eat a couple MPG but not enough to "feel").

Same thing here

I bought my 2002 vn 750 about two months ago and my bike does the same thing you are talking about when its cold. My VN only had 4000 miles on it when I bought It. This is my first shaft drive bike its a pain to lurch foward when the motor is cold. Pumping the clutch is not a bad idea. When the motor is cold try to let out the clutch very smooth its helped me BB KID

Oh... and KM - you recommend replacing the spacers as well as the usual clutch kit (springs and plates) - you thinking that my spacers are warped or???

Definitely looking forward to hearing from more who have similar stuff happening.. it's annoying as all get up.

And welcome to the forum BB... good first post responding to another saying "my bike does the same".!

EBC Kelvar, yes. The reason I said replace the "spacer" plates is , I did not do this, and after a few thousand miles the "grinder" noise returned..but not as bad. Another member replaced all the clutch plates and said he noise is gone.
Given the age of the bike, I would either replace the metal plates too, or as one member did, carefully sand each one to ensure a smooth surface.

Gotcha... thanks for the heads up.

It'll be a bit before I actually replace the clutch (that whole money thing) but I'll have to decide whether to replace the spacer plates (they're $10 a piece unless I'm missing something).

So I'll need the EBC kevlar kit, a clutch gasket, and possibly 8 spacer plates right?

I Think you only need 7 metal spacers.

In the meantime, it's safer and a whole lot cheaper to let the bike warm up and squeeze the clutch lever a hal dozen times or so before taking off.
It's a common malady of a wet clutch.
It'd be a shame to put in a new clutch, start the bike and take off and find out it does the same thing on occasion

It still SOMETIMES does it when I do the warm up squeeze clutch routine (probably when I don't let it warm up long enough). I ride daily and am often running late. When I'm leaving the house I'll slip the clutch a bit once I'm going and that tends to make things work better (I have 2-3 blocks of 10 mph before I hit the 45 mph main road).

Seems like the symptoms were better back when I was using the synthetic rotella... but I was using more oil when I was using it...

Ahh... the joy of vehicles old enough to vote...
