06 Vector - Middle Carb\Cylinder Problem

[rdog]

So, I started having some problems while riding. It seemed to get progressively worse to where I had very little power. After taking a look at it, it seemed to have a problem with the middle cylinder. Replaced the spark plug, swapped out the coils, tested the igition componets. Seemed ok..getting spark. The middle carb is also spitting out gas when running. The seld runs but the middle cylinder is not running. Also there seems to be oil dripping in to the air box. Opened the carb to see if the jet was clean also. Any direction would help, not sure where to go next on this thing.

Check your compression perhaps you have burnt a valve or broken a valve spring If you have low compression you will then have to perform a leak down test to find where the compression is being lost whether it is valves,piston or rings or head gasket

spitting out gas. could be the needle valve in the carb leaking past, over filling the bowl.
