engine vibration 3500 to 4100 rpm

[turtleescape]

I have a 95 katana 600. I have an engine viberation/buzz from 3500 to 4100 after that it smooths out and runs fine. Anyone have an idea. Thanks for any help.

Nature of the beast basically. Most will get the Ivan Performance carb kit and that does help take the buz/vibration out of it.

ALL inline 4's have a buzzy zone - albiet your is a bit lower than most.
i beleive it's usually in the 5-7k rpm zone.

mine is 6K RPM. That just so happens to equate to a little over 70 in 6th for me, which makes the highway very uncomfortable. By 7K, it's gone, but that's a little TOO super-legal.

When I ran my bike on the dyno there were massive dips around 3-4k and 6500-7000k where it was going super lean. After a little adjustment the vibration mostly went away in those spots but it is still there a little. I also got new grips and filled my bars with lead and now the vibration is almost nill.

5-7k which puts mine right in the power band range at speed.

mines are at 5-7k too
I should do the lead stuff too.

a good motorcycle glove helps also, make sure the palm is padded.

That's odd.. only place mine does that is a very narrow band ca 4.5-5.25K rpm. By the time i get to 6K it's a really smooth and comfy ride

I already ordered new gloves monday (yesterday) they should be here before my ride to Nova Scotia.
Here is what I got :

I don't think they are that good but at least they are red , which match my new jacket

It did not start until the bike was jetted.Would the viberation be from to rich or lean? I think it is running to rich but the mixture is set to 2 turns out. When it came back from the shop it was set at 1 1/2. The bike ran very poor and had no power. I took the carbs off and set the mixture to 2 turns out.It halls but now the viberation is driving me crazy. Im about to go trade it in.
Can the mixture be adjusted with the carbs on the bike?

could be either one. or even the needle height.
