MidRange vibration. Normal?

[Rothman]

I did some searching and couldn't find anything.... Is vibration through the midrange a commonplace for kat 600's? She's smooth as silk till about 5500 or so then you can feel it vibrate all the way up until about 7k or 8k after which it drops off and accellerates smooth a silk again. Is that normal? Anyone else?

My vibe is from about 4.5k to 6 dunno if thats normal though, we both might need to synch our carbs.

not really sure when was the last time you did a tune up or carb sync

The stock midrange vibration is normal. if you want to fix it, a Jetkit will do the trick

[Rothman]

Sync'd and tune about 3 weeks ago. That shouldn't be the problem. If there is a problem at all.

Really? a jet kit will get rid of that? That would be awesome. I love how smooth the engine is but once I hit that vibration it just annoys the $hit out of me.

I have the Ivan's kit installed, it is pretty smooth throughout
