They have been a number of folks on the Burgman USA site that have taken the CVT apart now. A fellow that goes by the handle of LeDude is doing his now.  As he is going along he is making videos of everything he is doing.  He will make all those available for others to use if they want to take theirs apart.

I've put a about 12,000 miles on my CVT since I replaced the belt and it is still working just fine.

I hope I never have to change it, but it is something I would try to tackle. LeDude has tons of useful videos on the Burgman.

Thought belts are a routine maintenance item?!

They are on most scooters with conventional CVT's with V type belts.  Those require belt changes every 15,000 to 20,000 miles. 

The ECVT in the 650 is a different animal.  It has an aluminum link belt and Suzuki doesn't give a replacement interval for it.  You don't replace it unless it breaks and that takes a lot more than 15K to 20K.  Mine went 80,000+ miles.  Since Suzuki doesn't specify an interval for replacing the belt they didn't bother to make it easy to get to.  I think they thought the belt would last as long as the bike.

Robster, that is what the belt in a conventional CVT looks like.  Not even close to the belt and ECVT in the 650.  Micbergsma is a good source for videos on the 400.  LeDude is his equivalent for the 650.

My 650 started squeaking a few months ago at about 40,000km so I took it in and they said it's the CVT belt and it's nothing to worry about. The guy also said replacing the belt is extremely time-consuming and expensive because it's basically designed to last the life of the bike so it would probably cost more to replace it than the burgman is worth so he said unless you have some emotional attachment to your old burgman, it's a goner once the belt snaps, usually at around 80-100k miles. I think you'd have to be pretty irrational to replace the belt on a burgman with that many miles, although I don't know what the hell you'd do with it then. It's nice to know that if my belt does go, I can replace it myself and from your description, it really doesn't sound hard, just time consuming. It's also nice to see everything the dealer told me can be corroborated here and vice versa.

I hate to tell you this but the squeak is may not be the belt.   If it is just an ocassional squeak that is very faint and usually occurs while you are sitting still then it could just bed the belt.  If it is more continuous and can be heard while you are moving then it might be the bearing on the primary pulley input shaft.

Did you ever watch the old Battlestar Galactica show and if so do you remember the sound when they would show one of the Chrome Cylon's with the red light moving back and forth where their eyes sould be.  If it sounds something like that then it is just the belt moving as the adjustor is cycling.

I remember the Cylons with their scanning red eyes but I don't remember their eyes making any sound. I'll have to youtube it.

Not sure why I just noticed this thread..could have been away for a spell. It began to resemble an oil change on a Spyder. Oh, did you change plugs? Either way, most impressive.

Since I replaced the one on my 650 I have helped two other folks replace theirs.  We used a method similar to the way that fellow did his.  Used a different method to raise the bike.  Used two bottle jacks, one under the passenger footrest on each side.  Then raised the body up slowly making sure nothing was getting in a bind. 

Using that method you can get the CVT off the bike and apart on the workbench in about a half day.  Much quicker than doing it by the book like I did when I changed mine.  Going by the book you strip the whole bike and it takes a good days work.  Of course it helped that I had already made up the set of special tools you need so we had them on had as the need arose.

Those are keys take are made of a special lubricated material.  They fit in grooves cut in the primary pulley shaft and movable pulley.  Their purpose is transfer torque to the movable face of the primary pulley while letting it slide in and out on the adjuster shaft to vary the gear ratio.  When those fail it does not usually cause the belt to break.  What happens is the adjuster will no longer work.  Either it locks in one ratio and refuses to shift or the belt gets slack and slips. 

The primary pulley assembly was not designed to be taken apart as a normal thing.  Suzuki does not even sell parts to repair it.  It is possible to take it apart but your on your own as far as coming up with parts and procedures to put it back together.  I haven't heard of anyone that has identified exactly what material the keys are made from.
