i find that caning it from a stop as a matter of course is a great help in preventing clutch shudder. mine only does this after many months of riding - at which point it's an indication that things need to be opened up and cleaned out.
This completely makes sense to me. While cleaning is necessary just caning it from a stop a few times helps. I find that the humidity brings on the shudder too. Now in the winter I hear it. It's not like a lion's growl thougt but a bit more like an unusual purr on steroids.

I get some squeaking at idle sometimes.

There isn't enough clutch engagement to make the bike roll forward at idle, do you think that the clutch needs any adjustment?

desq, it probably just needs a clean out of the bell at the next service with the pads deglazing at the same time. You can as some of the others are saying, just do a few fast take offs from the lights and it will help clear the dust temporarily. But I wouldn't worry about it if the clutch is not juddering. There isn't actually any adjustment as such on the standard clutch. Although some clutches let you alter the spring strength which can affect the clutch engagement point but I don't think the GTS standard unit allows for that. I stand corrected on that by anyone that's done it on the standard clutch.

One important point I didn't mention in my earlier post is this. Again many of you will know this already. Don't forget to keep the TRANSMISSION AIR FILTER clean. It's an often forgotten item by many. The 300 I began servicing last year for a friend had a completely clogged filter when I checked it. That's not good for lots of reasons.

1. it raises the transmission operating temperature considerably;
2. it causes the belt to wear faster due to the increased operating temps;
3. it allows more dust to build up in the transmission case and in the clutch bell potentially causing more judder and squeal. The dust just doesn't get blown out of the case as no air or a reduced amount of air can only get in;
4. potentially the clutch inner bearings suffer from the extra heat as this affects the grease lubing the bearings and it affects the seals. On Burgmans and some other makes I look after, it causes early bearing failure.

The filter is easy to clean but it just gets forgotten. Just a heads up.

Just chipping that I used to have this problem as a novice rider on my 300 but since adopting faster take-offs the problem hasn't reoccurred in a few thousand kilometres.

I suspect low-speed manoeuvring while lightly holding the rear brake doesn't help much either.
