Hi everyone.

 

I have a 1986 Harkey Davidson FLST and I know that the Evo's have an issue with vibration due to the way the engine is mounted to the frame but I was wondering if there is anything available to try and minimise the bike vibration.

Its OK at low speeds but once you get to about 70k/mh it starts up and it's a little difficult on long rides.

Any advice would be greatly appreciated.

 

Thanks Tony

sorry that should have been 1986 Harley Davidson FLST.

but still not a softail.

why is it not ?

Its a Heritage Softail.

yep I know , don't know about bobby though

as for vibes  keep the revs between 2500 to  2800rpm and dont lug it thats the evo sweet spot ,and iso grips but u have them

gel gloves , iso foot pegs  not sure what you would do with boards though

Hmm, My Softy vibrates more at low speeds, sure it isnt all the gear that you have on it thats causing the vibration?

Mines fine under 100 over that it's hand numbing after a while. From what can gather it's a good idea to check runout on the crank.

This was an interesting read as well

Yes all the engine and transmission mounting bolts are secure.
When a say "vibrating" I dont been rattling but more like after a long ride your hands and butt feel numb..

I might be wrong but I think it just comes with the territory TonyCap ... I know exactly what you mean , not so much a bad vibration but a fairly constant buzz through your hands up in the higher speeds .

My 99 Springer is the same and real noticeable when getting off my 08 Fsxtc and then going for a blast on the 99 ... I just figured it was normal as the Evo`s are solid mounted unlike the modern Softails that have the counter balancers built into the motors and the Dyna`s of course are rubber mounted .

Hey Perth hog what do these gel gloves look like ... are they pretty bulky .

lottsa things to look at re vibration, check pivot bushes on swing arm , primary set up , ect , ect.

I just spotted these and wonder if anyone here has used them with success.
