Hi, I have bought a Burgman 400 k8, 2009. After riding other scooters, I find that you have to give this one quite a few more revs before the clutch engages and it starts to accelerate. Typically, the clutch starts to engage at about 3000rpm, which seems a bit high to me. There also seems to be a bit of low speed judder, but it's not bad. With all the clutch problems, recall issues etc, I was wondering whether this scooter might be affected, or is this normal i.e. 'the nature of the beast'. Any thoughts and/or experiences very welcome, many thanks. (Scooter is very low miles - 2K).

Well....first of all - ya gotta get the starting RPM up to about 3500 before the clutch starts to engage......!!! and second.........If the prior owner was silly enough to follow the break-in instructions........the clutch pads are most likely now glazed and need to be scrubbed down with emory cloth or sandpaper....

THAT should take care of the "judder" on starting out...........!!!

I suggest you bring the RPMs to 4000 quickly when you start and as the bike begins to move, adjust the throttle. I think if you look in the service manual, you will find 2800 RPMs is when the clutch just begins to engage...but it isn't happy staying there.

As far as the low speed judder, that is probably a symptom of the low RPMs. Like trying to drive a manual transmission car in 4th gear from a stop.

Being a newbie to the 400, I just got my 2009 this past Wednesday, I'm very comfortable revving to 4000 to get her moving. Once the clutch fully grabs, that little bike is very peppy. Seems like the clutch starts engaging around 3000,when I'm moving it in the parking lot or my drive. I got mine with 3370 miles, and the bike is perfect.

Juddering.........?????? Or - squealing like a stuck pig.????????? They are different.

Juddering: shaking rapidly or spasmodically; vibrating conspicuously...

Thanks for the replies. No, she doesn't squeal, just some faint juddering, nothing too serious. The one other thing I was initially concerned with was whether 2K miles for a 4 year old bike was a bit too low? Don't these things have to be used to get the engine hot and seals lubricated, not sit around most of the time doing the odd trip to the shops....could there be some problems looming for me ahead?

This is a possibility, however the compounds used in modern seals/etc are very much improved as compared to those used when the "not good to sit around too much" axiom was first set down. It would not be a major concern of mine.

I would however change every fluid in the scooter; motor and final drive oil, brake fluid and coolant. And keep an eye on the tires as they are likely the originals and therefore 4 years old (once again though modern rubber compounds are much better than those of just 20 years ago). Most likely here is that they may have hardened up and may wear faster/not grip the road as well as they might...

I bought my 2008 400 in April 2011. It was new and had been sitting in a crate for that entire time. I don't know if the dealer puts the fluids in for the first time during the dealer prep, or if it had the fluids in for all that time. The only thing I have changed is the oil for fluids, and that just per the maintenance schedule. At 25000 miles, it runs like a champ.
