I awoke the machines day before yesterday, pulled them off life support (battery tenders) checked all fluids, and started the bikes.. The carberated 250 ninja took the longest to start, maybee 20+ seconds of cranking (total) but when it came to life i swear that bikes never ran that smooth. When i put them away last year both bikes got STAY-BIL & MMO in the tanks, i got a little carried away with the additives this go around and was expecting the bikes to protest.. i got the exact opposite, they both started with realative ease and are running flawless.. point of my post is im wonder if my very liberal use of additives has anything to do with the bike running so smooth, its like a brand new machine...
