93 K75 sat for almost 2 years pulled, new battery with fresh gas and ran like new out to my shop. Did full clutch spline lube with all general maintenance on the way out. Bike ran fine the out of no where starts running only on the 1 and 3 cylinder. Pulled 2 plug grounded to cylinder and have huge blue spark looks great. Put it back in on he head and back to no spark. Swap 1 and 2 coils around and now only 3 cylinder will fire. Bought new plugs and will be installing them in a few days to see what that does. Any help would be awesome, thanks!
