with the stock front sprocket they are buzzy at Interstate speeds. wht kind of vibration is it?

Ît,a vivration that goes to the handle like a electrical chock.

Normal for the 919 if it occurs at about 75 to 80 mph.

If you buy a front sprocket with one more tooth (17), it will lower the rpms about400 and the buzz won't happen until about 85 to 90 mph.

You loose the ability to power wheelie but not too many people riding a 919 are into that.

Add a tooth, get some better grips, wear good boots, add some Renthals, and consider some bar ends. But remember you're riding an inline 4 with its sleeves rolled up. Some buzz is expected.

what kind of "better grips" and "bar ends", any suggestions?

15 tooth will eat back tires like they're jelly doughnuts! But just as much fun.

I just had handlebars from a cb750 nighthawk installed (2" wider 1.5" higher), they came with the weights already inserted in the bar ends. I also had the original bar end weights retro fitted. The engine feels the same riding around town but it is MUCH smoother at 60 mph and over.

I just installed a Throttlemeister (heavy) and that seems to have helped quite a bit especially at higher rpm's/speeds.

I have an '07 919 that I wanted to knock some of the chrome off of a little bit...so I bought Renthal "Street Fighter Meduim" bars that looked great, but were 3 inches longer than stock (1.5"/side).
I thought about cutting them down...but noticed there would not be enuff straight bar to mount lever-perch, switch-gear, and grips.
I thought about using them as is (long) but this would have required cable adjustments from clutch, brake, and throttle cable/lines that I wasn't in the mood to perform. I only found out later that I also would have had to contend with locating pins and some drilling.

So, I had the stock bars stripped and powder coated black. They look great, but I am now getting a buzz that was not there before, especially the left side where at free-standing idle the clutch lever will vibrate and rattle like a beehive.

I'm reasonably sure I have the bar-end weights attached correctly.
I am at a loss trying to figure out what went wrong...and how to correct it. :-/

Hmmmm.....I don't see how powder coating could possibly cause the vibration. Have you tried loosening and re-tightning the pinch bolts, making sure their even? The clutch rattle at idle is normal. Oh yeah, I live in SD too.

took my 919 on highway for first time all stock ... was waiting for the bar buzz didnt get it tryed from 70 up to 100 ...i did notice the clutch lever vibration at idel...bike is smooth as silk and quiet ..im thinking different exhaust would create more bar buzz are the complants with bikes with stock exhaust
