I have a 07 an400, and with only 1900 miles on it, a shudder started to develope at about 2600 rpm. It contenues up through 36-3800, and then goes away. It makes no difference if it warms up or not. This will happen all day long.

After a ride, there is a smell of hot rubber, just like the smell I had with a 150cc chinese scooter. That scooter broke down with a bad variator, and the belt split.

There is now 2500 miles on the 400, same belt, same smell, same vibration, and I do ride with an extra belt in the trunk, and my extended warrenty with it. I think it just a matter of time before it hits the fan. LocaL dealer says they have no idea what is going on. Belt replacement is not covered by warrenty, but bad variator is.

Hope this will be of some help.

Hello, I have a 400cc K8 and at just under 2000miles on the clock it's started to shudder at speeds under 30MPH. Took it to the dealer who said it was an accumulation of dirt in the variator. They said it hasd been road tested and cleaned out, road tested again and was OK.

But it's not OK. It struggles to get up to 20 mph then it jumps into life, with a jolt that could throw you off if you weren't expecting it.

If I have to run for a long time at low speeds, it starts making a high pitched squealing noise. Doesn't sound right to me?

Any ideas? Bike is only 5 months old. Never been ridden faster than 75mph, but used at least 5 days a week on short journeys.

I also have a 2008/ Burgman 400.  Have the same problem.  Took it to the dealer and was told that it was dust in the transmission and was something inherent with the unit.  Why the dust only effects it at 15 mp is beyone me.

I have a 2008 Burgman 400. I just turned over 6000 miles on it.

A short time ago I discovered that it shudders when I take off, usually up to 15-20 mph and then it goes smooth again.

Anybody have that problem or heard of it?

Kinda want an idea what's going on before I head off to the dealer.

Thanks!!

I have the same problem on mine when it's cold.  If I start the Burgman and let it idle for 5 minutes or so before I ride, I don't have the problem.  If I start and go on a cold engine, I have the problem.
