Has any one removed the rubber mounts and went to a solid mount engine in a Dyna? If so I would like to hear the Pro's and Con's Of doing so.. I've always had solid mount shovel's and Evo's so I'm used to the vibrations but am wondering how going to solid mount would make a difference in cornering at higher speeds to eliminate the Wobble and I mean 60+ in the twisties.. And Please, I don't want to here then gat a softail or something, they don't have the ability to corner like a Dyna.. Thanks..

 

Whaa! Whaa! It's a Dyna! You're trying to defeat it's own purpose! OK, that's out of the way.

Interesting concept. I'm going to watch this one.

My concern would be that the swing arm on a dyna pivots through the back of the transmission case, and doesn't pivot on the frame. With the engine/transmission assembly being solidly mounted, there might be too much stress on the rear portion of the transmission case and it may crack or stress fracture after a lot of miles. I would think that the rubber engine mount would prevent that.

I don't know if that's absolutely true or not, just the first concern that comes to my mind.

 

People only had leeches their whole life until someone invented penicillin. Buy evo softail, before butchering your bike. JMO

 

Valid point and that's why I ask..

Invalid point, read what I asked... Please, your labeled as nothing but an instigator So please STFU...

WTF?!

 

Your bike, had fun with the project. if you ever sell it, it will be two steps above a parts bike for value. But maybe you can say that about about many customs.

I just think you wlll be throwing off the geometry and have a challenge. But get out the hacksaw and bondo and have at it.

 

I would expect to break something if you take a rubber mounted engine and bolt it up solid. It's not like they put that wearable part there for no reason. It'd be different if the engine was designed to be a structural member.

 

Vibrations have to go somewhere. I have said the same thing when someone was looking some aftermarket rubber mounts. Ridgid mount bikes were built that way from the factory. Now you can argue people been building bikes forever too.

What about a shovel with a S&S and all modern ammenities? But I realize the fun of a project, and now we have said it is a bad idea, so you really want to.

 

The only time I had a wobble on my Low Rider was when the head bearing needed replacing. The rubber mounts last well and the handling of the Dyna is awesome. So, personally, I don't see any advantage in removing the mounts. But, if you do, keep us posted, because if it turns out to be a great mod then others will follow!

 

Yep, agree, and FWIW that is the case in the Norton Commando world...the rubber "Isolastic" mounts are adjustable and if you get them too tight frame cracks often follow.
