A forum here that no one is using?

Okay, An item that seems to be up for debate is the Chassis Stabilizers for Baggers and Dynas.
I have a 09 FXD that I installed the Sputh Stabilizers on after upgrading the shocks and shimming the front mount did not get rid of the wobble in the rear at high speed turning.
I get a lot of argument about this being an unnecessary modification.
But the bike now rides like it's on rails.
Anyone else had this experience?

I have No personal experience with them... But I have had quite a few guys that swear by them..The only people I have heard call them snake oil, After asking how they effected there handeling admitted they have never tried them..
Funny how people hear something then become self appointed experts on a subject they really know nothing about..

After much research and perusal of the shop manual,I've come to the conclusion that the instability in the Dyna models is a combination of the Rubber mount engine and the swing arm being mounted to the rear of the transmission instead of the frame. This seems to allow the rear wheel to move independently of the rest of the chassis. Not having the rear wheel in a fixed track with the rest of the bike wold cause it to be unstable.

Makes sense... in fact it sounds to me like it's one of those "what the hell were they thinking?" designs.. you gotta wonder do these engineers ride what they Build???.. I am suprised that their track testers didn't catch it...Or maybe they did but they didn't want to spend anymore $$ on R&D .... Either way what really gets me and especially in th eautomotive field is how long it takes them to correct a bad design... The saddle tanks on chevy pickups comes to mind..
The started getting sued for people being burned to death in a T-bone accident whithin 8 months of the first model roll out yet paid hush money in case after case for twenty years without changing the design... Took 60 minutes and then a gov. Investigation before they did anything about it..WTF???

If they correct the design flaw then they are admitting there is a problem. That opens them up to liability lawsuits.
Cheaper to keep quiet about it and pay the occasional suit without admitting fault.

I hear ya but I woudl think that they would just quietly make th echanges and say here is the new improved model

When you take into account all of the costs (R&D, testing, retooling, and production down time), it was prob'ly cheaper to pay off the victims.

Probably was their train of thought but remember GM was almost bankrupted from the side saddle tanks that they kept in their design for 20 years... paying millions in hush money untill a reporter did a story on it... goverment ordered a mass recall... what saved them was a large number of those trucks were no longer on the road..

There's also the fact that they'd have to admit they fucked up. That's usually the deal breaker.

The problem with that is everyone who rides a Dyna knows they fucked up.
The problem is trying to figure out just how they fucked up.
Most riders that buy the basic tool for H-D, a shop manual, will start with realigning the engine in the frame by shimming the front mount. That will usually help quite a bit but the problem will still persist.
A set of shock upgrades gets rid of that rear wallowing under load also.
Unfortunately, a lot will then get distracted by promises made by the sellers of fork braces. Maybe on older Dynas they might help a little but the late models with the 49 MM front ends fork braces are not needed.
The TrueTrack or the Sputhe stabilizers are the best thing that you can add to your Dyna.
It's such a simple procedure to do it also. I installed both the front and rear Sputhe on my bike in less than two hours. The front one took about 1/2 hour and the rear a bit longer because I had to remove a muffler to get the bolts turned around. but neither was very difficult to do.
