2009 Vegas hesitation at 40 mph
I have a 2009 Vegas with 7,500 miles. My bike ran great all summer and then just last week I noticed a hesitation while riding. I notice it most when on roads that the speed limit is 40 and I'm holding it at 40 - 45 mph. I don't know how to describe it except it feels like something is holding it back. Like it's about to run out of gas. I don't have to pull over or anything, but it does make me nervous going too far from home. It seems to be fine while accelerating, When slowing down I get some popping from the exhaust. It's very hard to describe. Just a hesitation or stumble at lower speeds. Its probably there at higher speeds I just don't notice.
I've had the bike about 5 years and never had one issue with engine performance. I got the bike with really low miles and probably only ride about 1,000 a year because of the short riding season. Another factor is that I live very close to my work and sometimes ride my bike to work which is less than 2 miles. Sometimes I go right home after work without out going for a longer ride. I don't make a habit of that though.
A few years ago I noticed a similar issue and noticed one of the battery terminals was loose. I checked them now and they are tight.
I took out the plugs. In my opinion they look pretty black. Oddly enough one had white on the Electrode bridge, but not the other. The plug more toward the front of the wheel was more white. I cleaned them with a wire brush and reset the gap per the manual. One of them was off a little, but I dropped it several times after taking it out. Re-gapped and re-installed and rode about 20 miles with no difference.
I'm stumped because I don't know what could change literally over night. Maybe it is as simple as bad gas? I have about 30 miles left on this tank. I did just fill it before this all happened.
Should I change the plugs even though I only have 7,500 miles? Also, I'm not usually one for additives, but is there any additive I should consider?
Sorry for the long post, but I was just trying to give details.
Thanks in advance
