Default Source of vibration ??

I installed a set of V&H BSS, air cleaner and PCV last week. While on a road trip this weekend I noticed vibriation at highway speeds. I didn't have this before.

Is this from the pipes or do I have a tuning issue? The vibration was most notable in the floorboards. It's not terrible, it's just something I want to correct of it's abnormal.

Thx

I have had one of my motor mount bolts back out that made for an oddball buzzing feel.

You may also want to double check the Tq on yer pipes at the heads and the mount at the rear.

If you put the O2 sensors back in double check that they are tight. My back one was a little loose on mine right after I put my pipes on and was causing a buzzing at highway speeds. And like chaz said recheck all other bolts and heatshield clamps.

I plugged the O2 sensor holes. I'm going to retorque everthing tonight. I hope that's it. I don't hear a noticeable leak in the exhaust.

OK, I went back over each bolt and nut to ensure everything was tightenen to spec. everything was right on.....mounting bolts were torqued to 25 ft/lbs and the exhaust nuts are at 90 in/lbs...

The pipes feel good and snug and I dont' hear any exhaust leaks.

:-( --- However, the vibration is still there at faster speeds. I really dont notice it much until 40+ mph. At freeway speeds it's much worse. I feel it most in the footboards.

Could it be the resonance of the pipes? They do rumble alot and since I have the Goodies floorboard extensions maybe I'm just picking up the natural vibrations from pipes.

Ideas????

I need to have a few service items done next week so they can look at it then. This kind of crap just really bugs me.

Sorry no suggestions, no troubles like that with mine. What else did you do when you put pipes on A/C, fuel mgmt? Do you have stock baffles in?

I guess if I had reread your first post earlier I would have seen PCV and A/C. Who did your map for you?

If all the above checks out OK..

This may sound silly, but are U wearing the same clothes and shoes..
Some times I take a quick trip with my tennis shoes on and I have notices that at higher speeds my pant legs flapping in the wind against my legs instead of the boats gives me a feeling of vibration through the floorboards...Also once U notice it, it seems worse. Try to ignore it and see after a few trips if its still there.

Same clothes, same boots.

Ususally in higher gears because, as noted, the vibration is most notable at freeway speeds.

I'm dropping the bike off at the dealer next week for a warranty check. I'll ask them to check it out. I'll let you know what they say.
