But then again they came out in '84. I would venture to guess that most people on this forum were shi..... in their diaper back then, if they were even born. Lol... My first bike was a '71 FX that I purchased new from the dealer for 2300.00. Check it out.
I am not impressed at all with the bikes I rode.

With 2500 miles on the clock my front rubber mount was rubbing on the metal frame of the motor mount. You could actually see it removing rubber from the mount. Took it to the dealer and asked them about it. They said this is commom and they could trim the rubber mount down so it will have the proper clearance. After they did this the vibs were practically gone. They did this under warranty.

Can you please explain or perhaps a pic might help. I can't picture what you are saying. Thanks

you can see in the pic that the rubber it touching the top of the mount. also you can see a small piece of rubber that has been rubbed off because of this. since the dealer shaved it down a bit to give it the clearance it needed, it made a big difference in vibrations.

I've read bunch of posts about Dynas vibrating and some people putting shims between the lower motor mount and the bracket, well, i tried it myself yesterday and just like most post stated the motor mount separated from the bracket approx. 1/4 in on top and approx.1/8 on the bottom, i used some fender washers as shims and tighten the bolts, started the bike and could not believe just how much vibration that took out, thanks guys for sharing your ideas!
pictures please! you shimmed only the REAR motor-mount?

I believe he means the front mount. I did this when i was about 500 miles and it did make a difference. At 1000 miles i took it out since it was going to the dealer for the 1k service and i didnt want to hear anything about not being under warranty since i made a change. When i got the bike back i didnt put it back in. Soon after i noticed my front mount collaped a bit and was rubbing the rubber away. The dealer shaved it down so it has the proper clearance. Here is a pic of when i shimmed it with some washers. I to had about 1/4" gap.
