The idle seems low on my Burgman. When I first start it it idles at 1100rpm and it acts like it will stall if I don't give it a little throttle{which I always do}. Once I have gone a few blocks or so the revs come up on the idle but still seem low to me, at 1250rpm. Is this normal for the Burgman 400? I am used to this sort of thing since my old scoot is a temperamental 2-stroke but figured a 4-stroke would idle much better.

The service manual contradicts itself in the same paragraph (page 2-11). It says "set the idle speed anywhere between 1400 and 1600 RPM, and then it gives the spec as 1400RPM +/- 100 (which is 1300 to 1500). My GF's 400SK6 idles at 1600 at any engine temp and it seems to be happy there.

So then the idle speed is low. I looked up how to adjust and will try that. DUH I should have looked there first. Thanks for the help, mike!

I have a 2004 Burgman 400 and I experienced a similar problem is you. Try getting the rpm's at 1400 RPMs for optimal efficiency. You just have to remove the airbox and adjust that screw with the flathead screwdriver.

There seems to be a consensus that cleaning the idle adjustment screw is important for good fuel economy and idle performance. While you're in there, maybe you want to do that too. I think the service manual has the procedure for removing the adjustment screw.

Good Point, I Think the Screw has a Small Hole in it.. Worth a Look.
