My son has been having a continual problem with starting his 2002 SV 650. The bike has about 25000 KM on it. Sometimes when he tries to start it nothing happens but it will start with a boost, the battery has been replaced but the problem persists. The hardest time he had starting it was after it was dropped in a minor accident where there was absolutely no body damage to the bike, it took a few days of messing around to get it started, then it was okay for a week or so now it won't start again. I am thinking there may be a loose wire or connection somewhere but don't know where to begin. I was also wondering about the stator but to be honest my mechanical knowledge is very limited to say the least. ! Any tips would be appreciated.
