Why does your motorcycle idle fine but bog out when in gear?
Your motorcycle might idle fine and bog out when in gear because of a problem with the carburetor or the bowl. If either area is dirty, it will often bog the bike when in gear.
It could be your IAC, Idle Air Control. The IAC can be affected by temperatures. A test to see if this is your problem, start your engine and allow it to stall. Open your hood and VERY LIGHTLY tap your IAC with a hammer or screwdriver. Try starting it again. If it runs fine, your IAC is sticking. If not, take it in and get it looked at.
The idle speed and idle mixture are the first things to adjust and are very easy. If there is an off-idle stumble or a bog, you'll need to make adjustments to the accelerator pump and possibly the power valve to suit your engine. Here is a link to a Holley manual that explains it in detail: http://www.holley.com/data/TechService/Technical/Carburetor%20Tech%20Info.pdf
What make my 04 jeep rubicon lose power between 2 and 3rd gear It idles fine and doesn't stall so why the loss of power?
What causes a 1993 Kawasaki Bayou 300 to idle only in choke position and bog down when you push on the gas?
Possibilities are - stale fuel, how old is it? Blocked main jet or stuck needle jet. On choke, there is a little fuel which bypasses the main and idle jets, this allows it to idle with very little air. When you give it throttle, it uses all the fuel and air this bypass and idle jet can provide very quickly, and then starves for fuel as the revs increase. Basically the carby I would say…
