My bikes clutch sticks and all of a sudden lets loose slamming into action, this doesn't happen very often and only when the bike is still cold. Is it something to worry about?

That would be clutch shudder. Search for info ion the "Bluey Fix" or mod.

Clutch Shudder

.
.
I don't believe that the 'Bluey Fix' and clutch 'Shudder' are related.

My understanding is that the Bluey Fix addresses an excessively noisy, or 'rattling-sounding' clutch, while the engine is at idle. The procedure -- usually done with a hammer -- involves compressing the metal tabs against the springs in the clutch hub to reduce the amount of free play.

'Shudder' can also be described as instantaneous clutch engagement, or clutch grab. Some feel the shudder effect as the clutch plates are not contacting in a smooth, linear fashion. Others experience what feels like rear wheel 'hop' as the clutch is released.

For shudder, Suzuki is apparently investigating replacement of the Wave washer inside the clutch as possible solution.

I agree with others here that insufficient oiling could also be a contributing factor.

To mitigate clutch grab / shudder, which is most pronounced following a cold start, you should allow the motorcycle more time to warm up before starting off.

Those that have shudder should also avoid giving quick blips of the throttle immediately prior to releasing the clutch, which just aggravates the sitution. Instead, increase engine rpm's only moderately as you ease out the clutch handle.

Some claim that going to synthetic oil helps, although I personally found that it did not noticably reduce clutch grab.

If the bike is no longer under warranty, and the shudder is significant, then you should consider a clutch rebuild that includes the latest version of Wave washer & Driven Plate No. 2, in conjunction with new clutch plates.

It is a clutch oiling problem and the bad news is if it doesn't clear up on it's own you may have to take out the plates and soak them in oil. I have never had it but my techniques of riding might be different then yours. When I start her cold it takes a few minutes to back it out of the barn all while holding the clutch in (that's when it normally circulates the oil) then I precede at about 10 miles an hour down my long gravel driveway. I have the clutch lever pulled in at all lights(mostly for fast get-a-way situations) and I do use synthetic oil (Amsoil). I think Zoom suggested one could tilt the bike over to the right side as far as you could and keep it from falling with the clutch lever held in and the engine running to help circulate some oil in there...maybe he was just pickin' with me :D

Actually. those springs that are referred to in the above post for the Bluey fix do have a small amount involved in clutch shudder. Those springs are a damper in clutch engagement. Yes, oiling has a huge part in it, but those springs also have a part to. There are two plates in the back of the outer clutch basket. Those plates have those springs placed in them. Those plates are designed to slide against each other--one being fixed in place. When they slide, the springs get compressed more as the the torque is applied to the trans. Yes, the bluey fix was done more for the noise issues, but it serves to help stop some of the spring recoil also---unknowingly. If it does not clear up, pull the clutch apart and check the oiling. If needed, soak the cltuch plates and then, dig deeper. Do the Bluey fix and the tube nut also. You can also drill more oiling holes in the inner basket. You will be solving major issues in one shot. Just some thoughts.

I wouldn't call it a shudder, it's a delayed reaction in the clutch engaging, like it gets caught and then suddenly releases and slams into action.

Thanks, I've at least got half a clue now:bigthumbsup:
Mate, I have done about 30,000 k's and mine started doing the same thing and only when it is cold and not warmed up.I am starting to think that I never experienced it before 'cus I used to leave the bike idling and warming up while I put all my gear on and opened the gate ect but I stopped doing that a couple of weeks ago 'cus I read quite a few posts about the bike falling over when left idling.Might revert back to warming her up to get the oil circulating.

Mine has had "clutch shutter" since it had 3,000 miles on it. It now has 8,300 miles on it and I'm sick of it, and the dealer has no answers.

So I ordered a new bike which will be in the first week of May and I'll be trading in the 9.
