Hey guys, Today I changed out my final drive oil on my Burgman.. When I removed the cover, which was a challenge in itself, I notice there was a bluish tint on the right side pulley cover. (Not sure of the technical name) The photo below is not my bike, but I'm posting it just for a reference of the part I'm referring to The cover on the right has a blue tint like its been burnt. How concerned should I be? Thanks .

Cover turning blue means HEAT, make sure the air intake to the cvt is not blocked. The other thing is if you notice any slipping the clutch pads may be glazed and that also causes a lot of heat to be created but all you have to do is sand the glaze off the clutch pads.

Are we talking the clutch bell itself or where the clutch bearing rides in the CVT cover? Too fast an idle, revving the engine while stopped with the rear brake applied, creeping along at 5 mph and a clogged CVT air filter can all cause the clutch bell to overheat along with worn out or slipping clutch shoes. The bearing will turn its socket in the CVT cover blue if it is past time to replace it.
How many miles are on the bike?

Here is a picture...This doesn't look good. Hopefully someone can tell me it's not as bad as it looks.

That is your clutch pads causing that they must be slipping pretty bad. I have never seen one that bad. Alleyoop

The ride feels pretty normal...should I be experiencing or hearing something I shouldn't be?
What's the fix? Probably beyond my ability. Any idea of the cost for a shop to fix it?
Is it safe to keep riding until I get it dealt with?
Thanks in advance for your time in helping me out.
Dan

That can be caused by a high idle condition (does the wheel spin up while on the center stand with the engine idling?), slow speed riding below 10 mph (like when creeping though neighborhoods or cemeteries to go sightseeing) which keeps the clutch constantly slipping, revving the engine to hold position while at a traffic stop instead of using the brake or from worn out clutch shoes (does the engine speed up wildly when you give it hard throttle or just rev a bit and dig in solidly giving steady acceleration?).
You need to tell us which applies along with how many miles are on the bike. You also need to pull the clutch bell off and inspect the clutch shoes and see if they are worn out.

Thanks Rocky for your time to respond. No, the rear wheel does not spin while in idle on the center stand. Everything seems normal....My normal driving pattern is not slow speeds...I typically am over 55mph most of the time at or above 65mph. The bike has about 11500 miles on it. How much would I expect to pay a shop if the clutch needs to be replaced? Im thinking of bringing it in broken down to t he point as you see in the picture to save a few bucks on labor. (I have a trailer) With no symptoms, is it safe to ride? Again , I appreciate your time.

Hard to comprehend a clutch worn out on a Burgman 400 in only 11,500 miles. One would expect 50,000+ miles before you got to that point. Are you the original owner? If not possibly the previous owner like to sit at stoplights gunning the engine against the brakes heating up the clutch. If you can get a look at how worn the clutch shoes are and find that they have plenty of material left you can run that until they are worn down however you may just want to remove the nut and pull the clutch bell so you can clean things out. If the bell is still in the correct thickness range for continued use and the shoes are good then cleaning may get you going for 20,000 or so miles.

if it's working ok... just clean her up and run it till it does start to give problems. Replacing the clutch on these bikes is pretty easy... pull the belt, use an impact on the that nut (or a breaker bar with a freind on the rear brakes) and it will slide off... Lube the splines putting it back together.... clutch changes are pretty easy.
Getting the cover on and off is the hardest part of the change out.
It does look like it has delt with quite a bit of heat tho. Maybe the previous owner glazed it, then fixed the problem?

The previous owner was an old guy like me and I doubt seriously he'd be the type to sit at stoplights gunning the engine against the brakes heating up the clutch. My work hours dictates I won't be able to tackle this until next week.Again, thanks for your time. I'll take more pictures once I get to it next week.

I like watching Mic's video's . After watching I have a lot more confidence in tackling a situation, If there isn't one, then I'm not confident im up to it.

It's an 08....So if Im understanding you right....all I have to do is pull off the nut holding the bell housing on and that then will give me access to the clutch which should simply slide off? Then replace it with a new one?...No need to replace the bell housing too?

The thing that concerns me about the belt is a special tool is needed to hold the housing from spinning,
