HELP! Last night I took the battery out of my 1150GS, topped up the cells with new Distilled water, and put the battery on charge overnight. This morning, replaced batt into bike, started it up, but now it's not running very well. In fact, it's quite poorly! It sounds very lumpy at tickover, and when I try to pull away, it just stalls and tries to spit me off (Good job I'm bigger than most!) At standstill, if I rev the engine, it's definitely not smooth, and won't run up linear like it did before, feels like there's a fuel blockage until around 3000rpm, then it takes off as if blockage is cleared.
Can anyone offer any advice, before I get a nice bill from those nice people at BMW?!?!?!?!?
Pleeeeeease?
