Does one footpeg vibrate more than the other?

My left foot peg vibrates more than the right. It's the only part of the bike that I notice an annoying vibration. At 6k rpm and up the left foot peg starts to buzz a bit.

Is this a normal trait for a '98 VFR800 with 18,000 miles?

If both pegs vibrated I'd assume it was normal. But since it's just that one peg, I thought I'd ask about it.

 

Nope.... look into the chain being the culprit

 

I like my peg weights to be bilaterally symmetrical! :smile:

 

If you rode my TS400 for about one minute, you'd never notice vibration in your VFR again. When I sit on it, on the sidestand and rev the engine, it moves backwards about 1" per throttle blip.

Definitely!!

A chain and countershaft sprocket that is worn out or a chain that is adjusted too tight will cause a strong vibration to felt in the left foot peg.

 

I initially assessed the final drive to be serviceable. I will look more closely but my gut tells me it's not a chain problem....

It doesn't quite feel like any driveline induced vibe I've felt before (and I've felt a few--I threw a chain on a HawkGT once ). Plus, I've found discussion of this same 6000k rpm left foot peg buzz. I'm learning that some years had a peg weight added--presumably to "fix" the peg buzz.

I think that implies this particular vibration is a characteristic of at least some VFR's. Perhaps I'll replace the chain/sprockets first. But more likely, I'll add the peg weight first.

The buzz is not major. Part of why it stands out is because the rest of the bike is quite smooth. I'm no stranger to major vibes either. I figure if I can handle the sometimes punishing vibration my CR500R imposes, then I'm not a fuddy duddy about bike vibration. :wink:

BUT, removing the buzz would be an improvement and it looks like there's a reasonable way to do it.


Thanks for everyones' input. It's been very helpful. :biggrin:

 

Yes but no. It was the 2000 model year that got the LH peg weight.

 

i have both a '98 vfr and an '89 hawk gt... the vfr seems sewing machine smooth in comparison

 

My 2000 VFR has a mass damper on the LHS footpeg. It does not totally eliminate the NVH, but it does mitigate it significantly. 6000 to 7000 RPM is the range in which the vibration is the worst.

NVH is a challenge with a stressed member engine.

Uuuhh, Non-Volatile Harmonic? Neutral Velocity Hummingbird? Naturally Vibrating Harmonica? Noisy Vibrating Hammering? :smile:

I give up, guys. What does NVH stand for?

 

Sorry.... NVH is Noise Vibration and Harshness. It's an automotive/motorcycle engineering acronym....

My initial thoughts were that driveline (chain/sprockets/adjustment) were the problem, though lacking a dampener weight might enter into the equation.

When I had a '96 VFR, with similar issues, the Honda techs also checked the motor mount torques (found to be ok). Replacing chain/sprockets and cleaning out all the gunk built up around countershaft sprocket cured the problem.

VFRs are not totally vibration-free, though they tend to run very smoothly compared to many other bikes, especially if in a proper state of tune.

My suggestion would be to try the footpeg weights first, if the driveline is determined to be ok. If that doesn't do it, replace chain/sprockets.

Note also that if boots are too tight, foot will have increased sensitivity to vibes and get that numb feeling. Good circulation (through looser fitting boots, gloves, jacket, etc...) helps to eliminate physical issues often associated with or blamed on vibes. ymmv.

What part nos. do I need to do both pegs? I don't see anything on the fiche that looks like a weight, etc.

 

My left foot peg vibrates more than the right on my 99 VFR. When I was reading about the 5th gen VFR on its original reviews, two riders/writers commented on the left foot peg vibrating more than the right at around 7k rpm.
