I just bought a used 1991 1500 with 93,000 miles. It seems to be in pretty good shape, but the PO has no service records and the bike needs some attention. The price was right, but I should have looked her over better and test-rode her longer.
Last night I was riding with a passenger (maybe 350lbs. total). Temps were in the high sixties and we got into some traffic. Sat and idled for several minutes at a time. Went maybe a mile idling at lights and creeping along. Several times the bike stalled or almost stalled when taking off from a stop. Seemed to idle ok and ran ok once we got moving. Started right up when I killed it, but I'm not sure what the stalling means. The temp guage needle was pointed straight up when we were in traffic and dropped back down when we got moving again.
Where should I start troubleshooting?
