this noise i am hearing only occurs when engaging clutch into 1st and try to pull away , shifts fine into and out of gears up and down , no clutch slip while in gear ,
So it sounds exactly like marbles in the transmission area or clutch ? its defiantly not the CCT
the bike is difficult to pull away from a light the clutch seems to make this marbles sound and i have to be easy getting going , but after that shifting into 2 ,3 or 4 ect is fine its just at the initial take off from 1st gear
any ideas ?? bike has 30,000KM not miles on it all regular maintenance up to date.

Back to the shop for the princess!

Slipper clutch makes that noise, but from my bike @ 50000k it's a lot quieter now than it was @ 5000k. Not an expert (yet) on the slipper clutch but I vaguely remember posts on wear causing noise. I'll bow to more experienced members on this.

I have owned the bike since brand new i know these bikes can make a lot of noise but this is defiantly a clutch issue , it is even worse when bike is hot , as you release the clutch in first as it trys to engage the clutch is making a chatter or more like marbles rolling around sound and is tricky to get going , all other gears are fine no clutch slippage , up or down only out of 1st almost like if the clutch springs are not putting enough pressure on clutch plates ??
seen another thread where someone was replacing entire clutch basket springs ??

Time to pull the cover and have a look-see !!! Something worn beyond minimum spec (my guess) or broken (not likely based on your symptoms described).

So have clutch out everything looks fine , there is some play in the shaft that the clutch goes on , maybe 3mm in out
Is it possible the clutch basket bolt was simply not tight enugh ??
This is a hard one to trouble shoot but all clutch plates, and everything is ok

A little movement in the shaft is normal... the clutch hub nut pulls everything to the right and takes it out. Was the nut loose?

well it wasent loose loose ! it still needed a impact gun to get off but my mechanic thinks it came off to easy ?

every thing else looks good ! clutch is in almost perfect shape , basket is fine , bearing are ok , shaft bearing is fine , maybe the springs are not putting enough pressure on the clutch thats what it feels like that the clutch is hopping or chattering when tring to engadge clutch off a stop light

side note when bike is cold clutch is fine untill it warms up or gets hot then its really tricky to get going ? but clutch does not slip at all full power in all gears

Loose nut was not your problem.

That is called "Judder" by a lot of technicians. Can be caused by glazed clutch discs. Can also be caused by some oils.

Many bikes have damper "anti-judder" spring washers in the clutch pack....some old bikes had rubber rings. I haven't looked at the parts list for your clutch, so don't know if MV uses such devices.

On a Suzuki M109 cruiser, if the judder spring is installed wrong or lost its flex (basically a big conical washer), the bike will shake violently during initial engagement. I mean violently !!

New plates and fresh quality oil is my suggestion.

What oil are you using?
