pulled the carbs and cleaned them out a bit, today.. bike started up after some hard kicks, but now it's turning over with ease more and more. the problem is, the right cylinder is VERY weak. as in, if i unplug the sparkplug.. it doesn't even change how it's running, but dies almost instantly if i unplug the left. where should i start in diagnosing this? should i enrichen the carb on that side more?

check valve clearances, check for vacuum leak in carb manifolds, then if not fixed...leak down test?

switch the coils (if a dual setup) and see if the problem moves, could be bad coil, bad lead wire, bad cap, or bad plug also check the wiring to the coil, what does the spark at the plug look like?
