Hoping someone can help me with this issue. I have a 2001 ST4. It was stored in a heated garage last winter, I connected a batter tender to it this summer and it started perfectly, rode it only two times in July and then was parked for 2 months (this past Thursday). When I went to ride it, the battery was quite weak and didn't turn over very quickly. I connected jumper cables to a car, started the car and tried to start the Duc. It turned over fine but would backfire and emit a "pop" underneath the gas tank. I would wait a few minutes between tries and then fire it up again, only to have it turn over, back fire and pop on occasion. This went on for a period of time, perhaps 15 tries or so. I tried putting fuel injection cleaner in the tank, swished it around, tried a few more times and got nothing. So I went home.
The next morning, I put the key in and it started right away... Apparently the battery got enough of a charge from all the boosts that it maintained a charge the next morning. I rode it for a minute, shut it down and it started immediately. Then rode it for 5 hours, it ran and started beautifully, no issues.
Does anyone have any idea what the issue might be? Would really like to avoid the frustration of having that happen again.
Open to any suggestions.
