Buzz buzz!

Last week I put on a new bar (renthal medium) put in a new tune (based on one I found here for the trs's) and added a sw motech center stand. I also swapped out my front tire around this time. Since then, it seems like buzzing in my footpegs has gotten a lot worse. To the point that my feet go numb after less than a half hour. Could adding the center stand have caused this? Or maybe the tune? Has anyone else had experience with this?

Ahhh, got ya. I can't see how a different map would increase the vibes. Although a good tune could have a good vibe!

Does it do it at a particular rev range? Does it do it at a particular speed? What happens when you pull in the clutch when it's vibrating?

It's worst in the normal buzz range from 4000 to 5000, but it doesn't seem noticeably worse in the grips or anywhere else, only in the pegs, which leads me to the center stand being the issue. Haven't looked into it a whole lot yet to see what might be rubbing/vibrating more, just thought I'd see if anyone else has had a similar issue.

I wouldn't think the centerstand would do that. Heck, the added weight should help.

Try the simple stuff first. Change the map/tune and see what happens.

not necessarily... the added weight could bring the assembly into a harmonic which occurs around that rev range.

My suggestion, where ever the centerstand stops against, put a nice 1/4in piece of rubber so that it cushions the centerstand. If that doesnt work pull the stand off and see if that solves the issue.

Hmm...I know...totally diffrent animal but after doing a TPS reset on my XB I noticed more vibe in the pegs, not so much in the bars but alot in the pegs, alot of the mapping/timing is based off of the TPS....just throwing out some ideas

If it makes you feel any better I noticed the vibes in my footpegs after I installed Renthal Mediums. I can't remember if they were there before, but now I notice them.

Doesn't bother me, but perhaps yours are a tad worse?

That's odd, maybe it was there the whole time and now that the bar vibes are gone you notice it.

I have a (Honda) centerstand, and I don't notice any vibration in the (stock) pegs. Do you have stock pegs, or non-rubbery aftermarket ones?

Stock pegs, and I already had an aftermarket bar with pretty good bar ends, so the vibes aren't a whole lot better (I'm not running any bar ends right now) and I don't think it's the same as before. I had to hover my feet for a while on the ride home today because it was an almost painful buzz. I tried keeping my right foot on the peg and lowering the center stand while riding today and it didn't seem to make a difference. I'm gonna try to remember to switch the map back tomorrow before work to see if that helps.

i'm assuming the buell is closer to a thump thump than a buzz buzz though...

well, I switched the map this morning and it seemed to help a decent amount with the buzz in the pegs, but now it seems like the bars are buzzing moreI'm probably just crazy.... I guess I'll just tinker some more, and worst case I can use it as an excuse to get a custom map made!

Can you set the mapping in the middle, then the buzz will be stuck in the gas tank
