m-1324 service bulletin
Has anyone heard of this service bulletin? Has to do with Dyna excessive vibration.

 

16 May 2012 M1324 Service Bulletin When my Wide Glide was new I had all sorts of odd vibrations, decel shuddering, speed instability, etc. At 600 miles on the ODO I replaced the front isolator which had collapsed and was contacting the engine bracket and performed the vehicle/engine alignment.

I ended up needing to shim my front isolator 1/4" to allow it to be in the position the alignment wanted it to be in and not be simply placed under stress again setting up another failure. With correct alignment there were no more shudders or vibrations, the bike tracked true; rear wheel was squared up in the fender. There has been no off vibrations or instability since then and the isolator shows no signs of distortion.

Just because a bike is new doesn't mean it's been correctly aligned

Hard to get a shot of the front isolator with the Jagg in the way but you can see the shims and longer grade 8 bolts needed to put the bike alignment where it wanted to be...

 

I measured the distance between the from isolator and the bracket and I had zero gap. I followed the service bulletin and filed the rubber on mount for a .020-.040 gap and carried out the alignment....test ride tomorrow.

 

I've gone through two front isolators... **** poor design if you ask me. Rubber is being held in 'shear' force... not what rubber is best known for doing well.

Definitely do the vehicle alignment. I've had mine up well over a hundred... without stabilizers...etc... pretty solid. It got dicey when the front isolator wore out.

I also installed the Predator mount... I like it so far.... but I'm running a bunch of other 'new' stuff, so haven't really pushed it hard yet.

 

Fork bearing adjustment?
