Engine hesitation

I recently got a 2006 C50 with 6500 miles. Everthing works great, except for one little glitch .... when I get out of the flatlands around here, and in some hills, I notice that on a modest downhill slope, I get some hesitation on very slight deceleration. It is a very narrow band of rpm where I notice this. Accelleration is fine, and a greater deceleration rate is fine - it's only when I'm just trying to maintain my speed on a slight downhill.

I thought that, with not being used a lot by the previous owner, maybe the fuel injectors were a little gummy. I've run several tanks of Sea Foam- treated gas through it, but it doesn't seem to have helped.

I previously had a Vol, and didn't notice this quirk. Is it normal for a C50? If not, any suggestions?

I got an 07 and have not noticed it doing this.

No clue why yours does, someone will be alone shortly.

It's a very slight, intermittent miss. It doesn't happen at any particular rpm, just on a slight deceleration at any given engine speed.

I bet it is the PAIR valve.

Aftermarket exhaust?

Stock exhaust.

Would the PAIR valve cause problems after only about 8k miles?

It gets clogged with carbon pretty quick. Only reason it is there is so the bike will pass emissions.

From what you describe, it sounds like there are no problems with acceleration or fuel economy. You just hear something strange on deceleration?

Different brands of gas, all regular grade. The plugs have only about 1k miles on them..... but I appreciate your input.

That may be it ... there is a very subtle popping/jerking when I am in very slight deceleration mode, but no problems at any other stage of acceleration or heavier deceleration.

I didn't think of the PAIR because my old Vol had 40 k miles on the original PAIR, with no noticeable problems.

I'll be busy for a week or so, but will try to do the "adapting" after that.
