If anybody can throw some input in - it'd be greatly appreciated.
Just for a little background on the bike:
I have a 2008 fz6 s2. It's been my every day commuter for almost 4 years now. It's got 25,000 miles on it, I've done 3 oil changes in its life - one at the beginning of each season. I've NEVER changed the air filter and know I need to - and its on my list. I've never dropped, tipped, or layed her down ever. The only mods I have are scorpion cans. Everything else is purely cosmetic (well frame sliders too). I've recently bought and installed a new chain and new rear tire. The clutch was tightened and a few things lubed by my mechanic less than 4 weeks ago.
Recently I've been experiencing a strange, hard to describe, feeling when I'm in the very low end of the RPM range (under 4k). I feel it mostly when I'm in slow moving traffic - with the clutch semi-depressed - working the friction zone, rear brake, and very low end of the RPM's to provide low speed stability (learned that at MSF).
The best I can describe it is that when I'm using the friction zone and the low end of the RPM range going 5mph, I can feel a sort of pulse. I can feel it in the somewhat in the clutch. I also notice this feeling when I'm in a high gear going slow (again using under 4k RPMS). It feels like something is moving, or maybe a slight "knocking". It's not loud and obvious, but only barely noticeable. If you weren't riding the bike, you wouldn't even notice. It almost feels like something is either loose, or maybe misaligned?
I'm not sure what would cause this as I am not too mechanically inclined. But at first it was slight, and over the period of a few weeks, has been getting more and more noticeable. I have a mounted cam on my bike and helmet - and was hoping to have some sort of video documentation to bring to help describe the issue - but the video doesn't display the problem in any sense.
So do any of you know what could cause a low RPM pulse feeling, as if something was loose, misaligned, or rattling. It is not noticeable at any RPM higher than 4 or 4.5k. Is it a possible sprocket issue? Should I look into getting new sprockets? Could it be transmission related? I doubt its related to the clutch because I feel it at times when the clutch is not in use.
Any input is greatly appreciated. If ya need any pictures or audio of up close, or any questions answered to describe it further - I'll do my best.
Thanks again.
