Can you tell me what year? 1100's to 1200's have vacuum pressure balanced carbs. You can find a way to make a balancer on line. Very simple. (I have an 1800 and don't remember how). If you have an 1800, mine did the same thing, also lost big time gas mileage. I replaced the O2's. Didn't help. I ended up replacing the fuel pressure regulator ($50 part) which is a 6 beer job since it is between the rear cylinders on the left, and you have to remove the shelter, the flow vent in the fairing, spread the outer fairing away from the bike, and get a 10mm ratchet to remove the lower fairing braces. IF you have an 1800, you need to pinch off the fuel line and return line. Replace the fuel regulator, and make sure you RandR the two O rings on the tiny cylinder inside the regulator.
First the false fuel tank has to be remove. Once remove the air filter has to be removed. Underneath the filter is I believe four screws that have to be removed. This exposes the carbs. Remove all lines hoses and cables and behold.
Not sure what you mean by a slide moving, but it sounds like a carb based issue. Carb balancing needs to happen at idle, like most people know, but ALSO at 2500 or so, actuated by throttle control. Balancing at the higher speed makes your machine run tons better and last longer.
Usually the compression runs 140 to 150 range. If you have 105psi on all cylinders it just means poorer than normal mpg. The bike is big enough at 1500 cc to still have a lot of power for the road. The good thing is the equal psi in all cylinders. Generally a difference of 10 % is the max you can get by with before engine vibration and 'missing' at idle shows up. So if your bike still runs smooth and starts well, don't be bothered too much with the 105 psi. Once it hits 90 or less it really should get a fresh top end.
