GSXR 600 L5 vibration issue

Hi,

My L5 has developed an increase in vibration through the bars which is related to engine speed.

It happens whether I'm moving or stationary. It used to be super comfy but between 4-6krpm my hands are now going numb! Clutch in or out it's the same and letting off the throttle and using engine braking is particularly vibration inducing!

I've check the exhaust, put weighted bar ends on etc and still the same. Bike is currently on 8000 miles last serviced in January 2019 when it was on 6300 miles.
I've done 3 trackdays since aswell.

Any ideas?

Does the vibration go away above 6k rpm?

My ex k7 600 was the same between 4 and 6k. I just rode either below or above that range. Some have used foam padding on the clip ons fitted over the stock grips which may help.

It eases off then gets worse again. The bike is running fine, no loss of power, no change in sound. I'm really at a loss with it

Check to see if the rubber vibration dampers on your motor mounts have worn out. That's the only thing I can think of that would transfer vibration while stationary.

Are all the engine mount bolts tight? (There are no rubber mount dampers)

Check for loose exhaust mounting and points where the exhaust system may be hitting the frame. Also there are some rubber mounts on the exhaust, make sure they are not bottomed out.

I've checked exhaust etc and all looks fine. I haven't had the fairings off yet but won't have time before my trackday on 6th July. I've managed to get it into a garage next monday to have a look at it so I'll update then. Fingers crossed it's nothing serious

Where are you riding the 6th? A couple of us will be a Carolina Motorsports Park and a few of my friends will be at Road Atlanta.

When did you first notice the vibration?

After the service?

Is it possible the chain is too tight or not lubed sufficiently?

Does the vibration come back at higher revs?

On the track you won’t be down at 4-6k much.....

I noticed it this weekend so a good few months after the service. I'll double check the chain. True I wont be down in those revs often other than one really tight hairpin.

It's there a bit at higher revs but when you let off the throttle and the engine starts braking there's a real buzz through the bars now.
