[QUOTE="Harald, post: 1396413, member: 8054"] Another part to look at is the starter relay. I had one replaced under my YES warranty because it would click, but wouldn't close the main contacts consistently. Worked fine for many years until my starter failed. I had one of the infamous bad oil seal starters that I rebuilt to fix the problem. After the rebuild the bike would sometimes still not start with the authority I would expect. I hooked my volt meter across the starter relay main contacts and found about 0.6 volt drop across the contacts when starting. I suspect the super high current draw through the relay deteriorated the contacts causing excessive voltage drop. A new relay I put in reads less than 0.2 volt drop and now my 130,000 mile FJR starts with authority! [/QUOTE]
