Improved slipping grabbing chattering clutch
I too have been victimized by coffee grinder noise and grabbing chattering clutch when my VN 750 is cold -- and it only occurs when starting out in first, not when upshifting. I got pretty sick of it. To the point when I was cringing whenever I shifted. No fun.
Some time back I posted on this topic (I can't locate the post now) and there were several suggestions, the most useful of which were to warm the bike up first (not my first choice), work the clutch several times to warm up the plates, and switch to synthetic oil.
So I started using Syntec 10W-40 with little to no improvement for the price. 1600 miles later the problem was worse than it was last year.
I also tried warming up the clutch plates. This works best if you have the bike in gear and slowly let out the clutch until the bike creeps forward a few inches, then repeat about 4-6 times. The trouble with this method is that the problem will just repeat every time you come to a stop until the oil warms up.
I can now say that I gained the most improvement switching to Castrol's full synth motorcycle oil -- comes in gold bottles and it might as well because it's as expensive as gold....still, it WORKED. Tendency to chatter and grab when cold is 90% reduced -- which is significant to me because the problem was making me really PO'd -- and the engine runs smoother, shifts better, and is generally a joy to ride. I have never had a change in oil make this much difference in any vehicle. The downside is that I HATE to drop $40 on an oil change for a motorcycle but if that cures the problem, and if I can wait a little longer between changes (it is synthetic after all) it is worth it.
