So after riding some more and listening carefully, it is a squeal type sound, not a grinding sound. I have taken the advise of previous posters and have been taking off hard a lot more to limit the amount of time the clutch is engaging. I have attempted to de-glaze the clutch by holding the brake and giving it some gas for a brief moment. The sound is just getting more and more frequent. I am going to go in and talk to the dealer that did all that work at the end of last summer. I will probably also find out what my pay off cost is and sell this thing for what I owe and get rid of it. I don't have the time, the money or the patience for this, I want something I can just get on and go.
Thanks for paying attention to my previous post. I will try to help you as best as I can. Sorry for your troubles, BUT this thing is easy and fairly inexpensive to work on and fix. You got TOOK in paying $1,000 for that work! But some places charge $1200 or more for the same thing, so it could have been worse. This is why it is so important to be able to do the work yourself. The dealers and shops charge a lot of labor and it runs the price up real high. If you knew how easy this thing is to work on, you would not be having any of this trouble and you could be out enjoying your ride quietly!
I can't say exactly what is causing your problem, but if I took it apart and looked into it, I would know exactly what the problem is and what to do about it. It would be nice if you could take it apart and send us pictures of the inside of it, so that we could see what was wrong and what you needed to do. If it is only squealing, then it must be the clutch or the belt. The clutch could be glazed, and if it's not that there could be a problem in the torque multiplier (driven Plates) that is causing too much slack in the belt and therefore belt slippage and squeal. The Clutch should never glaze if you give it plenty of gas when you take off, and the belt should never slip under any conditions. The shop could have not put something together right, they may not work on Burgmans all the time (don't know about the place you took it, if it's a big busy dealer or not).
Look at this recent thread by Glerin with a Burgman 400 CVT problem, this is the same as yours:
CVT check - to my horror :/
I've got an 08' 400 and it has NEVER squealed, and I have always done all the work on it myself. I've worked on cars and motorcycles all my life. If you don't know how, you could learn, it ain't Rocket Science!
I would not trust anyone to touch my scooter or anything of mine, I do not trust them, especially a dealer (stealer). There is one private scooter shop near me that does good work, and I only use him for tire changing. There is a ton of info on this topic in this site, just use the Search Box to find your answers.
