First off this places rocks!!!!

ok now on to the questions...

i have a 07 650i Brute

its running like crap... it spits and spudders, backfires like crazy and dosent seem to have as much power as normal. I was thinking about pulling the carbs off and cleaning them and changing the plugs... Just figured i would ask around before tearing into my brute.

Thanks in advance.

Troy

it is a mode that limits the bike to 3500 rpm i think. anyting past 1/3 throttle sounds like the reve limiter is activated.

I had the same problem after I sunk mine, coughs and sputters, no power and hard time getting too WOT, backfiring etc. I got frustrated with it, after running seafoam through it and checkin plugs etc, so I took it too the stealership. Found mud in the bowls, cleaned em up, and adjusted the valves while it was torn apart. Have ya sunk her at all? or been close and didnt think ya did and maybe she got a gulp? Cause that sounds like the problem, but one of the many other master minds here will probably chime in with some other possibilies. Good Luck and welcome too the site, great bunch of guys and gals here

Use a drill or screw-gun with a phillips bit is best. It'll knock 15-20m off. Oh and don't push to hard on the screw's holding the little black pocket side things on.
