I'm to the point of being really tired of my clutches chattering so bad my mirrors look like they're going to fly off! It also seems to maybe slip a little, then grab HARD and get going. Also there is some belt 'groaning' mixed in. If I power brake it a little, it seems to smooth out for about 2 or 3 more stop and Goes in town.
I'm ready to tear this thing down, but what are the 'main hitters' or things I should be looking for? I took the CVT cover off and blew it out twice with no difference. (I wish I would've checked the belt for it's condition.). I do not milk the throttle to get going, never really have as I've read on here not to. I'm lost, please help. :?
My bike is a 2012-400 with 6800 miles on it. This is not a slight issue either, it shakes bad!
Thanks.

You Can Try What Chris, Mention is to Gun It? on take off!! it seems to work for some!! Or to Dump the Stock Parts there a Problem atleast 2 of them replace with After Market Parts, Sliders,Clutch sometimes fixes this Problem...

Don't have those problems since i replace atleast 90% of the transmission ,Belt,Clutch,Varaitor,Torque Springs, You only need to replace One or 2 things of your choice. Air out seems to help But Water cleans Better.

With a 2012 model, do you still have any warranty left? If so, I'd let the dealership deal with it, even if it is inconvenient. They may end up doing something major, just to take care of any causes to the problem.

The system is pretty simple...which makes it aggravating when it doesn't work right. Plus, not many have had problems with it. It sounds like you have it open. I'd look at those variator weights. Check them for any flat spots and clean the tracks. If you want to go the extra step...which isn't called out for in the service manual...find some dry lubricant and spray that in the tracks. I want to stress this part...don't use graphite or anything that leaves the surface wet. You're better off to use nothing, than to use that. It must be a dri lube, or the lubricant will pick up the dust and clog things up.

I'd look at the CVT belt and check it for being within specs on the width. Then twist it to see if it is delaminating. It'll look fine at rest, but you'll see where it is separating if you twist it. If you see evidence of that, replace it.

I really think you're problem lies in the clutch pad area though. Can you pull the clutch bell off and post some pictures?

If you decide to replace the clutch, I was working on a HiT clutch that should take care of your issues. PM me, and we can discuss the history, what I've done, and where to go from there.

One thing that you may want to try is to pull the cover off and remove the clutch, inspect the clutch bell and more important.......you may want to look at the 5 clutch pads and see what the edges look like.... They may not be seating on the bell properly. try beveling the leading edges of each of the shoes with a file......! Re-assemble and do NOT put the cover back on but run it on the center stand.and just listen and feel for the judder..............

at 6800 miles worn clutch pads would also be a sign something else is wrong, ditto on the warranty thing, if no warranty left
on center stand , does engine idle with back wheel not rotating?
at what rpm does wheel begin to rotate?
does it roll without excessive friction when clutch not engaged?
what is gas mileage on average?
how much tire wear is left?
give us a few rpm's at speeds
was final drive oil dark when changed?
is there any free beer at your place? :blackeye:

First off, it has warranty to the end of the month. I e-mailed them noting that Tuesday I go for a total hip replacement (at age 48) and was having trouble not only getting the bike there, but really concerned about getting the bike back, but they did not reply. I e-mailed through their website so It may have went in their spam, so right now I'm going to send another one to the salesman who sold me it.
I have a feeling, and always did, that my bike was abused by shop personnel the first 5 or 10 miles of it's life. I also think the belt has worn V spots in it from hard power braking, but I'm not familiar enough with this type of CVT. in the snowmobile business I am very qualified in CVTs so I want to get inside one and see what makes it tick.
On a side note, the inside of my CVT cover and the CVT area is fairly clean, just some expected belt dust. I saw a video where Mitch had oil and/or grease on his clutch.
On a snomobile, the engine is the "Primary" or "Drive" clutch and the other(would be the one by the wheel) is the "Secondary" or "Driven". What are they called on the Burgman so I can read you guys correctly?
Thanks for all the great advice! :thumbup:

I would call them as well as email them. Perhaps even send them a certified letter. Email can be deleted and the recipient can say he never saw it. With all three things, it would be hard to deny being told something was happening.

This is just so sad, because it's aimed at a nice, smooth, relaxing, quiet ride, which it does quite well, but I guess I just have to get this sorted out. As of now, I would not buy another one, however, I still love my Burg :thumbup:

on the 400 when you open the cvt case the thing in toward the front of the bike is the variator, the thing in the back is the clutch, and the loud noisy thingy is the girlfriend
the hot vibratey thingey is the engine and the go rounder thingey is the back wheel , at least that's how I keep them straight :cheers:

I must've missed the call, but had a voicemail asking me to get my bike down there before warrantee runs out. He said a few other things and sounded very sincere.
I'll have to drop it off in the next couple days, but I won't be able to let you guys know what happened for a while.

Mike, that's fine. The important thing is to get it fixed...and for you to heal up afterwards.

The 400 is a sweet running bike. What is happening to yours is not what the rest of us experience. Let the dealership get sorted out what is happening and you'll be in love with it from when you twist the throttle initially, instead of just when you're cruising along.

I know some of it is 'nature of the beast', and I'm ok with that, but this is truely unacceptable.
By the way, I'm noticing a lot more belt groaning, or deep screeches now.

I wonder if you have a clutch pad spring broken.
