I was just curious if it can be done and if so has anyone put the counter balanced B motor in an iso mount Dyna. Might be really smooth everywhere and minus only a couple of HP.

 

My "A" motor does just fine.... vibrates a little more when cold, but I doubt the motor swap would be worth it.... just buy a softail.

 

I sat on a Softail. It was eerily too smooth.

 

Do all dynas have the A motor? And why does the A motor have more hp than the B?

 

B motor has counter balancer(s?) that sap a little power.

 

After riding a softail I know my Dyna was the right choice for me and I like the bouncing around motor at idle. I was just wondering about the B motor because I know that the B motors do vibrate in the softails at higher RPMs due to the rigid mounting but idle very smoothly.

 

if you went with a "B" motor wouldn't you have to add an oil bag as well?
