Its a crap shoot with this Bike

[flynrider]

Being a retired aircraft mechanic I was sometimes tasked with fixing vibrations/"buzzing" at different power settings. Nine times out of ten I would find chaffing conditions in the engine compartment. Check your bike out to assure there is no metal on metal contact anyplace. I have an FJR and installed engine guards with highway pegs, at installation I didn't catch the peg bracket was chaffing some plastic.................at certain speeds I would get a minor buzzing sensation...........repositioning the bracket cleared it.

CB,

Thanks for your response. I have not added much in the way of mods to the bike. I did take the shield off last week to see if there may be some buffeting going on but the bike actual felt a bit better at speed with it on.

There was a post i responded to (can't remember the thread) where a member said his older CB750 felt less vibs then our bikes. I responded that my GS1100 is much smoother at highway speeds than the CB.

I've found mine to be very vibey most of the time, to be honest. When I first bought the bike last year, I had planned on putting a LOT of miles on it.. but I'm just taking it in this morning for the 8k service (they threw in a prepaid maint plan, 2 years unlimited miles, everything covered but tires and brake pads).

Unfortunately, my hands go completely numb in about 45 minutes on the backroads or highway, or in about 20 minutes with city riding. It doesn't seem to come through the tank or pegs much, just the bars. I've tried re-positioning the bars, making sure the dampers and bars were set up properly, and new bar end weights - none have helped much.


I actually bought a N1k about 2 months ago as well, spectacular bike but a bit too much to trust myself with on my daily commute. I work nights, and the stock lights were absolutely terrible. Even replaced, it's way too easy to ride too fast for them.

My hands never feel that bad even after a tank of riding. Riding my GSXR750 would give me pins and needles after 100 miles.

The N1K is a great bike. I found it to be smooth and has a great gearbox. A little more aggressive position than my XX, the faster you go the smoother and more comfortable it gets.

Yeah, that was me. I found it particularly interesting since the CB750 is not equipped with bar end weights for vibration damping.

I've been experimenting for the last few weeks and have been finding that typical cruise rpms on the CB11 (around 4K) is where the buzz is most prominent. At one point last week I noticed that the bike seemed like it was running smoother. That's when I looked down and noticed that I'd neglected to shift into 5th gear (again!) and the bike was humming along at 5K rpm in 4th.

As I posted previously, having owned many vibier (is that a word?) twins, the CB11's buzz isn't much of an issue with me.

Flynrider, my 750 has a slight buzz at 61 mph or about 4100 rpm. Does yours? Its not terrible but you notice it. I feel it through the grips mostly. Otherwise, its as smooth as butter.

I haven't noticed it, but then again my typical highway speed is usually above 70 mph. I'll give it a try this weekend and get back to you.

Hey F7, I gave it a try this afternoon and I did feel a very slight vibe at around 4K. It wasn't much though. I never would have noticed it if you hadn't pointed it out
