ok i have a 2001 rmk 800 and it keeps wanting to bog then die at a certain rpm. It wants to bogg down and die at about 3000-4000 rpm if the throttle is held there for more than a second. It started happening some time between when a equalizer bottle was put on and the throttle slop was ajusted. The dealer ship said to blow the carbs out with air but i did that put the carbs back on and it still did the same thing. The throttle isnt held open at all ither so i really dont know what to do!
If all you've done is add the
boost bottle then the carbs need to be set up to accomodate the changes in air flow. I've used these bottles on a few different engines and they all needed tweeking. This is instructions from my SLP bottle (you can get this from their site also)
I hope this helps. Good Luck!

The boost bottle, will cause the idle speed to increase. For
example, if it idles at 1600 RPM, when the bottle is installed the idle may increase to 2500 RPM.
This is caused by insufficient puddled fuel being converted to efficient atomized fuel by the boost
bottle. A good thing! Seldom ever does the pilot jet require changing when a bottle is installed. To
adjust properly the following must be done: 1) Idle must be reduced to proper RPM level by
adjusting the idle screw on Mikuni carbs to 1600-1800 RPM. If you try to reduce idle speed with
the air screw adjustment or pilot size and not idle adjustment, the optimum performance will not
be achieved. 2) Fuel screw adjustment needs to be adjusted at running temperature to achieve
the best throttle response. Fuel screw adjustment range is ½ turn (lean) to 2 ½ turns out (rich).
Testing at different settings will be worth while to accomplish the best performance instead of just
“setting to a given spec.” This way you can adjust for your particular atmosphere.
