Iv'e been tryin to get on top of mine for years, cause mine constantly lives outside. I've bought two new battery's, and have discovered that if i don't use my bike every day summer and winter, the alarm i have on my bike will kill the battery in a week due to the constantly flashing led light. so now i've bought an oxford oximiser and keep my battery off my bike till i'm gonna use it alot. The only thing i've found is that if i try and start it from dead cold(like now), the battery will probably not have enough power straight away to start the engine that has stood for some time, so i usually bump it first off to keep the battery full. Then after using it for a few day's it's fine. If i leave it two weeks it's dead again, so i just take it off and charge it indoor's. Don't know if anyone's got any more advise for me, would be gratefully recieved.
