I just had the same thing happen on my bike (25k miles). Turns out you should replace your battery every two years, regardless of whether you are having charging problems. The sulfites in the battery build up and cause a large current draw which makes the alternator work hard all the time. I pulled my alternator and it was cooked in some place and had completely dissenegrated the wires in another. Take a look at your alternator and you will probably find the problem. I should receive my new alternator ($150) this week from Electrex USA (built much better than the OEM version).ghostrider314 said:i havent had time to do that, but if it help the diagnosis, the other day when i went to go riding it was as dead as a doornail. i had to run-start it like ten times before it would stay running. then i went for a quick ride and that problem happened again where everything started fritzing and the bike was bogging really bad. but when i downshifted to pull over it went away, and was fine for the rest of my ride. go figure. i should be able to get to some further testing this week.
interesting coincidence that we had such a similar problem. i'll check it out and get back to you...thanksBaldman said:p.s. I checked my charging system a week prior to all the problems happening with mine - yet everything checked out good. When I checked it this time, the alternator was completely gone (no charge being placed on the battery). If you are not measuring around 15VDC @ 5k RPM, check your alternator.
