the dreaded shudder!

Got me some shudder when taking off at around the 2,000 rpm level so am sure I have early onset of clutch problems. Only at around 3,000 km (1,800 miles) so maybe a warranty repair. Could it possibly be something else and what are the issues with riding it before I can get it in for repair?

I've experienced the shudder with three different maxis. I had a SW that did it, as well as a Burgman 650 and my GT. The easiest way to prevent it is to open the throttle with a good twist to get the scoot moving and the clutch locked. Lower power settings from a stop will allow the clutch to slip longer.

When the shudder starts to happen, a few aggressive take offs should clear it up. The pad surfaces glaze up on the clutch causing the shuddering on take up.

A good romp out in the twisties also helps as well.

The ultimate solution is to fit a Dr Pulley HiT clutch.

The fact that it just developed and was not there a week ago doesn't seem too bad to you? I guess I just have to make sure it doesn't get too bad.

I have worked with machinery and vehicles all my life, there is no such thing as perfect!! I know when to worry, and when not to.

The shudder can come and go with changes in temp and humidity, which also effects belt squeal.

Good point - we have just recently (and since shudder started) started getting temperatures in the 65-75°F range. Didn't make the connection but as my wife always says "no brain - no pain".:D:D

Wet clutches have problems of their own including more difficult access when they need work. A dry clutch doesn't put debris in the engine oil either. Unfortunately there's no free lunch. For this kind of CVT system I much prefer a dry clutch. In fact I like the dry clutch on my K1100 more than the wet clutch on most of the other bikes I've owned. With a dry clutch you can use friction reducing oils while wet clutches restrict types of engine oil you can use. There's good and bad on both sides of the question.

I remember the fun I had with my Venture Royale if it sat too long between rides (like after a long stretch of snow/ice in the winter). You had to make sure you had your right foot FIRMLY on the rear brake because the first time you started the bike (even if it was in neutral and you were holding in the clutch) the bike would lurch forward before the clutch plates freed up. That NEVER happens with a dry clutch.

On the plus side, I never had to have the ass-end of the Venture Royale disassembled every two years for a spline lube either.

I have the dreaded shudder as well. I have 3500 km on my scoot. I thought I might have burned the belt like I did on my skidoo. Glad to learn it is just glazing!

Remember kids, no need to keep working around it and trying to deglaze; just put in a Dr. Pulley HIT clutch and problem cured, forever!

It's gone now. Not sure why but perhaps much warmer and humid weather has caused it to go.

Hey Colin,

Yeah, same thing happened to me. Comes and goes, actually. I've taken Bill's advice and power past the RPM slice where I originally noticed the issue. Maybe that has helped me not recognize any issues lately.

Funny how all bikes have a "thing" that looks like an issue but is just the nature of the beast.

Like I said in the post above, launch your scooter like you mean it and you won't have any clutch problems. Slow, gradual opening of the throttle won't let the clutch lock up as quickly which means increased wear. Much like slipping the clutch on a manual transmission, you need to get the clutch spinning fast enough to lock up with centrifugal systems like this kind.

If it's under warranty get it to the dealer there is a bulletin for this issue, they replace mine under warranty for the shudder.

While it's gone it would be amazing if it came back at about 19,000km just before the big service and they had to replace belt as well ;););)
