Bog off idle and up?

[QUOTE="RM_guy, post: 915093, member: 20652"] First make sure everything is working properly. If you suspect the PV isn't opening then pull off the access cover on the right side of the cylinder and move the PV lever by hand. It should easily move and then spring back quickly. If not then it is gummed up, so clean it up so it moves easily. After you are sure everythnig is OK mechanically then look at the jetting. A BAWHH when first twisting the throttle indicates a lean condition. Turn in the air screw until it goes away. If you have to turn it in so it is turned out (:think: :)) less than .75 turns then you need to increase the pilot jet size. With that said you could still be rich at the needle or main jet. I typically like to start with the main jet and work down to the air screw when jetting. There are several good threads on jetting properly. The Maxima 927 oil that yu are using is an excellent oil but it contains castol oil that can gum up the PV quicker than other oils. I ran it for years until I got tired of having to clesn everythig up frequently. You may want to try something without castor oil. In any case, pick an oil and ratio (32:1 is plenty) and stick with it. [/QUOTE]
