[QUOTE="ALFJR, post: 1457624, member: 574"] As stated above, check the battery voltage with the engine running, preferably something over 3 or 4K RPM. Voltage should be something greater than about 13.5 volts. I had a similar problem on another bike, and it was related to the charging system. I know the battery is new, however, you could give it a good overnight charge, then measure battery voltage with the key off, engine stopped. Then ride the FJR until the problem shows up, then measure battery voltage with key off engine off, and look for a significant voltage drop. compared to the reading right after the overnioght charge. I had a Suzuki with symptoms similar to yours and it turned out to be a charging system issue. I know the FJR is not a Suzuki, and the the FJR is much newer than the bike I had, but given similar symptoms and the above simple tests have no parts cost, I thought to present the above. I am hopeful you will get this resolved soon! Cheers! [/QUOTE]
