  • Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

Cold engine clutch chatter

AA Class
My 08 TE510 clutch has started to get grabby and chatter, but it stops after the bike warms up. It started when the bike had about 2000 miles on it and it seems to be getting worse as the miles add up. The clutch otherwise works flawlessly, and there is no sign of the problem after the engine is up to normal operating temperature.

Has anybody else had this problem. Any suggestions?
 
Since it is only an issue when cold. Could be your oil/ not just viscosity but how well it works with your clutch- your disks may be sticking especially the inner most ones. If you were to take them out and clean them it may help for awhile. Sometimes deglazing them and roughing them up with some sandpaper will help.

if it happened all the time- then you'd be looking for warped disks and notches on your basket fingers and hub.

I've swapped out the oil brand three times. The problem gets progressively worse. Yesterday it was bad....embarrassingly bad. I couldn't leave a light without the bike junping like an impatient Shetland. I guess it's time to take a look.

The clutch has just under 4K miles. Is it worth replacing the plates at this point?
 
I assume the bike warm but the oil not 'hot' yet at the light... then it got better.
I had a bike that did that- "impatient shetland" is a good description.

If you don't think it has to do with temps/oil/viscosity at this point... and you don't think it has to do with your hydro clutch (shouldn't)
I would inspect the plates- they may glazed/polished or or burned/warped- you can check them for trueness against a piece of glass. Check the hub and basket for grooves. While you have everything out- mic the plates for minimum thickness and mic the springs for min length.
If everything looks good, you might want to inspect your clutch rod- do a search- there has been some discussion on some rods not having proper heat treatment and improper wear creating burrs. Simply cleaning the plates and roughing them up with sandpaper helps in a lot of cases- sometimes the grabbyness will come back sooner than you may hope though. (on my bike that had that issue- I'd clean and inspect the plates once a year- then replaced the plates and it was good for about 18monts and needed to be cleaned and roughed up again...probably could have replaced the basket and hub but didn't want to spend the cash)

Clutch replacement time is hard to predict- I have over twice the miles on my 09TE450 as you and still have the original clutch without any signs- replacing the disks could improve things instantly or not- but they may also not be at min spec- they might just be glazed or overheated. I wouldn't expect you need a clutch overhaul at your mileage.
