Stock exhaust mounts and right side vibrations

I have an 09 Mastiff that has the right peg vibration at higher rpm. It has vance and hines exhaust with the bracket bolted directly to the frame. The stock pipes have a 2 piece bracket with rubber mounts between the brackets that isolate the exhaust from the frame. Im going to modify the stock bracket to incorporate the mounts and see if that stops the right side vibration.
Has any one who is getting the excessive right side vibration tried this?

And if it's still there, I see a pipe made and say one pipe vibes and one off the same jig does not. With that said, I want the pipe to start at point A and where the hanger mount lines up, I do not pull the pipe down to meet B. I bracket the hole up to [wherever point B] lined up statically sitting where A has the best fit.

However, high rpm is like throwing a pebble in a pond and watch the vibration waves occur. WOT say if the vibe is still there with all the rubber baby buggy bumpers being thrown at it, well, you have to swallow that 1 Ton Man Pill and live with the vibe and that harmonic at said rpm and just hold on and concentrate way out ahead and stop looking at the front fender vibrate along with the rest of the bike giving off that energy-wink-wink!

PUTT or PUT UP with it. Check the hardware and test before robbing from baby :whoop: :eek:

I already tightened the coil cover bolts which have steel washers under them and put a 1/2 inch lock washer under the top bolt to make sure it threads all the way into the chrome spike nut. The vibration is on the right side and shakes my foot off the peg.
Sven..thanks for the alignment info and I can do without the rest of your crap. When something is wrong i prefer to make it right.

Dsled, you are welcome and do not take the slanted posts personal. It is not your fault the bike vibrates. Not your fault I am thinking things out and the engine balance kicked me in the crank. See it? We tape that penny on the fan blades until we find the whooper. Switch it to max rpm and it purrs along. Same as saying my [higher] crank speed needs a penny someplace?

And before you do it right and balance that engine for higher rpm; here is something to think about. Take the concept and toss it in the trash if you will. Had a very bad vibration thru the handlebars. I measured the handlebar caps to have equal gaps between them. Used a set of feeler gauges between those 4-pinch-gaps to hold the bars on. The high rpm vibration was gone believe it or not was a forced racing issue put upon me.

That said, I now balance fork axle caps, fork pinches, handlebar pinches, and if that foot mount had a balance or some gap you could balance out that vibration, it's one bolt short of a teardown and run a balanced engine if high rpm is your territory.

I love the vibes the evo engine puts out.. wont have my foot vibrating off the peg either..If your that good it would be good for me to learn.. maybe you can post some YouTube videos of the precision work you do.. You must have some nice bikes stored up as good as you are.

You and The Sven are 180 out from each other and Mastiff's don't pull Dogsleds! :eek:

Must be the Mary Jane - they just unleashed the dogs in Colorado and missed the Mastiffs.:roll::roll::roll:

You need some karma for those bad vibes.:cheers:

Hell of a deal. :whoop:

Na.. We are alot alike.. I use a centagram scale to weigh out my ceiling fan weights and he uses coins.. Same results. My original question was has anyone with the bad vibes on the right tried using the rubber mounts that came with the stock pipes. Thats all I was looking for. Seemed simple.

I don´t think the rubber mounts would be the answer (or yes for exhaust vibration, but then it would not fix the shaking of your foot off the peg!

I would find the cause of those "bad vibs" and doing so you are also doing some good future "Damage Control"!

Just saying :cheers:

I don't remember if the stock pegs have the adjustment screw or not, but my aftermarket ones do. It adjusts the resting angle of the footpeg relative to the peg pivot.

This adjustment made a big improvement to keep my feet on the pegs.

If you have one it will be easy to find, just flip up the peg and the adjustment screw will be pointed toward the ground. If you have this adjustment screw and you adjust it, you will need to re-locktite it. I didn't and the screw on the passenger pegs fell out when I was riding solo with the passenger pegs flipped up.

The stock ones do NOT have it, instead they have a locking pin which hold them in an angle which did not suit me.... I removed the locking pin, turned them to the (my) right angle and now my boots rest flat on (the flat spot) the pegs. It does make a difference.

Somewhere there is a Thread where this subject is discussed with pics also.

Either way.... I still think this will not solve his "vibs" problem, I have never had my pegs vibrating that bad at all.
