On my way back from a brief trip a week ago, as I was pulling into my drive, the engine seemed to stop/start quickly. On subsequent trips, at speeds over 45-50, it would seem to stop/start where it was as if you had completely rolled off the throttle and then went back to speed. A short lunge and then back to normal.
Heading down for some BBQ with a few other FJR types last weekend, it got worse. Once, I noticed my tach needle go waaaaay up and quiver, before dropping back down as if it was doing the start routine. Another time, the letters ERR flashed across the dash LCD before the engine came back on. At first I thought, well, my cruise control is cutting out. But then while at the BBQ place in Stephenville, the bike would go dead, the radar detector would say 'low voltage' and the Garmin would warn it had lost power.
Since it seemed like it might be due to some electrical issue, I unplugged what I figured was the biggest drain, the Denali lights, from my fuse block under the seat. We diagnosed a low RPM in idle and will check that later (out of town now w/o the FJR). But low idle is not the issue at speed obviously. On the way home, the engine dropped out or everything seemed to turn off multiple times on I-20 at speed. Very disconcerting when there are 18-wheelrs all around and people in massively oversized pickups who want to know why you on that dang bike are not going 89+mph!
Finally reached up and unplugged the radar detector somewhere in Ft. Worth, probably 30 miles from home and the bike ran fine all the way home.
So, apologies for the long post but any collective wisdom would be appreciated. I plan on doing a quick 100 miles this coming weekend with and without the detector running to see if that is the real issue. Note, all my electronics are routed to the Eastern Beaver fuse block *except* the radar, which is plugged into the pocket 12volt.
