After warming her up good loosen up the mounting bolts on top of the muffs. Then get the center mounting bolts and leave the exhaust flanges last. No need to loosen any slip fitting clamps unless you think the slipon's are turned a little.

Tighten down the exhaust flanges first then the center mounts. Then warm her up again. While as hot as you can stand it torque the exhaust flange nuts then tighten the muffler supports. Leave the slip on clamps last.

This has worked for many but if it doesn't work for you at least you have the satisfaction of knowing it isn't in the exhaust. It's very rare for someone with your tune& mods to get a vibration unless, the stage 1 flash wasn't for the correct bike. I've seen stranger things happen. Stay with it... with a little patience you will find the cause.

Question, you don't have a True-Trac or a third mount point added mod do you?

 

I think we are on the same page... this should fix his vibe's

Wiz,
The answer to your question is NO


When you say Tighten down the exhaust flanges first then the center mounts. do you mean snug them up? Then warm her up again. While as hot as you can stand it torque the exhaust flange nuts then tighten the muffler supports. Leave the slip on clamps last

 

Yes, once your exhaust sytem is centered you can then tighten the muffler slip on clamp... ( o-ring metal clamp)

Sniper is dead on... he's saying your mufflers and dual head pipes are out of line and in a bind... this is transferring the exhaust vibration to the frame where you feel it in your floorboards.

If you had a third mounting point such as a Tru-Trac, they too have been knows to send motor vibrations to the frame.

I did what was suggested and I still have the vibration in the floor boards and highway pegs between 2100 and 3000 rpms then it smooths out again.

I tried running down the highway and shutting off the engine and the vibs go away I also tried just pulling in the clutch and the vibs are still present.

When I put the tip of my finger on the air cleaner (at the same time I have the vibration in the floor boards and highway pegs) I can feel the same wibes I get in the floor boards and highway pegs.

I put in a new set of plugs and a new front motor mount and I still get the vibration.

The vibration feels like a strong buzz under your feet. No vibration in seat or handlebars

Thanks

Rick



Can this be a tuning issue?

 

Could be rick... if you worked on the pipes and mounts and the vib is still there yet gone when you shut down it could be in the tune. Stranger things have happened.

If you ask your dealer about it they will give you the same song and dance given to everyone else... harley's vibrate, get over it.

May want to try a tuner such as a TTS (my fav), SEST or PCV or TMax. You could also try a local Harley Indy tech and ask his opinion.

My vibration is gone now but yours is something else completely different than the norm. At least you have the normal causes checked and fixed so you can go from here.

 

Just wanted to say thanks to Mr. Wizard, snyper77 and everyone else. This thread is many months old and still helping newbies. We just did the Stage1 and the fuel pak and the advice found here was just what I needed to fix my newly acquired vibration problem.
