This one is buzzy
« on: June 17, 2018, 06:37:46 pm »
Hi guys,
I'm sure this is an old tread but here goes!
I picked up a previously enjoyed 2011 C-14 with 19K on the clock last month.
I also have a 2013 ZX-14R sport tourer with 11K on her and she is a smooth as it gets.
I took the Connie out for a run yesterday and I tell you when you when you get up around 80mph she buzzes so bad you would think she was going to explode I did a 9K trip in 2012 on a 2011 GTR and I don’t remember anything like this.
Anyone seen anything this severer in their C-14 travels?
Thanks in advance!

My 16 gets a bot buzzy around 5K revs. Then buzz subsides all the way to redline.

My 2011 bike I got with 6K on it.  What gear / rpm are you running when she buzzes enough to explode at 80mph?
And does she buzz through the seat, pegs, handgrips or brake lever?

As I recall, a motor mount bolt re torque and or throttle body sync fixed the problem, maybe. Seems like Murph's have some heavy bar weights to take the buzz out of the bars.... I'm sure someone with experience will chime in.  Good luck, Tim

Try switching back and forth between the regular map and the ECO map. See if it has less buzz with the ECO map. Most find after a good ECU flash that the bike is much smoother, but remember that if you have mechanical issues they still need to be properly addressed. Steve

I also have the same 2 bikes, a 2013 ZX14r and a 2010 C14.   My ZX14r is smoother than the C14, it just is.   I rode double yesterday on a 225 mile round trip with cruising speeds from 55 to 90, mostly 65, 70.   I have some buzzing at 80mph as you mentioned but nothing that bad.  I never changed my speed based on vibration levels.  If my hands get numb it is always the throttle hand I'm sure from gripping it harder, but it does seem like the right bar has more vibration than the left.   Loosen my grip some and it helps.   Maybe I didn't notice vibrations much since my rear was in discomfort from the stock seat.    That is a different issue.

Mine has been flashed, and even though the flash reduced the vibration on the right handlebar considerably, it is still there and after half hr it will put my hand to sleep.

I need to re tighten the engine mounts and do a throttle body sync., but right now it is the middle of the riding season and I just wanna ride. Maybe over the winter :)
Best,

How do the tires look? Fill them up about 5lbs from where its at and see if it changes?

Something is a miss if it is that buzzy.

I'd start with checking the engine mounts, and then TB sync.

Is it possibly loose fairing components buzzing or the engine/drive-train?

The buzz could be a bunch of things. If not mechanical, one cylinder being dead due to a bad injector or no spark could cause ugly running.

Agree with others, the latest zx14r motor is a real gem. It is a crying shame the C14 doesn't have it.
