Problems at 2500-2700 rpm

I mentioned in one of the previous posts that on the ride home from work of day two it was sputtering in the 2700 rpm range.

One option is that it wasn't warmed up enough, I doubt that was the problem since I know it was warmed up.

Another is that the air filter and plugs are in poor condition. Which is another possibility. I will be getting new plugs for it as well when I get the air filter at autozone along with a gap tool and plug wrench. Even if they are fine, having another pair won't hurt, and I need a gap guage and wrench anyways. I might have a wrench that will work for the plugs though, will need to see.

According to one of the guys on the Harley-Davidsonforums.com, it is likely a needle jet that needs to be shimmed or the bike needs an air/fuel adjustment and possibly a larger pilot jet. I have no idea what those are, but will eventually get to them if basic fixes don't do it first. I would also like to post pictures of where each of the drain plugs are when I do that. So stay tuned for those.

I've also got some S&P? carb and fuel injector cleaner. I'll put some of that in as well and see if that helps.

The bike has been sitting for a while, so I am hoping that it is just dirty.
