My 998 quit on me today. I need help figuring this one out. I'm riding out to Moto-GP at Indy next weekend with a bunch of guys and I don't intend to miss it!
I just finished going over it. re-checked valves done 800 miles ago(it was my first time so I wanted to see if they would "bed in" at all), changed fuel filter to the Napa version that LT Snyder recommends and generally went over all the electrical connections and sensors to make sure all was well. Changed oil and coolant again.
Problem first started after a ride on memorial day, we got rained on pretty bad and the tach went nuts, then later every time I'd roll into the throttle hard, especially at low RPM she would backfire until I rolled out of it and downshifted to get the RPM's up. Twice it just quit altogether. It would always restart immediately after I stopped however. These problems seemed to clear up mostly, I went over many of the sensors to make sure they weren't retaining water and all was well. The tach continued to not function properly. BTW, yes I checked the brass screws, they're all tight.
During this recent service I discovered the battery connections and ECM ground had become corroded, not bad, just a bit, and the battery connections were loose.
I corrected these items, put some dielectric on the battery terminals once everything was connected to ensure it wouldn't compromise the connection.
I took her out for a shakedown and she ran flawlessly for about 4 miles and then just quit. No drama, no backfire, even the tach was acting right again, then it just stopped running. I wasn't in the throttle, I was cruising at approx 45MPH about to turn into the gas station. While waiting for the trailer to show up I began working on her. I found the main charging fuse (large 40A fuse next to relays under battery) is blown. I bypassed it with some copper wire I had, no dice. The infamous "white connector" for the regulator looks fine. I disconnected it which should have made the bike run off of battery alone I think, again no dice. I may have pinched a wire behind the battery box when I put everything back together but I haven't confirmed this yet.
Any suggestions on what else it may be?
Even without the charging system it should run on battery alone right?
All other fuses are fine, a blown charging fuse should only have lit the charging fail light right?
