Hi, A couple of weeks ago I took the bike out the garage as usual and she would not start. Eventually she roared into life just as the juice was about out. Since then no probs until this morning came out and turned her over until the battery was deid. So turned the car round gave a her a jump and she started like a dream. I stuck a yuasa battery in maybe 3.5 years ago and would not expect this to fail after such a short period. Although the fact that she started with a jump makes me think that the problem is not fuel related. I have done nothing to the fuel system in 4/5 years. I used to check alternators in cars by seeing whether the headlights were getting brighter when revving. Might do that tonight. I don't want to stick a new battery in then knacker it.
Any ideas?
