Has anyone paid attention to the vibration/shake of the motor on their touring bike versus any other bike? The engine on my SG shakes a lot more than my Fatboy.

 

I believe that the difference is in the engines. The softail has the 88B (balanced) while the SG has the 88 engine which vibrates a bit more

 

NOT STARANGE AT ALL. THE STREET GLIDE IS RUBBER MOUNTED AND THE FATBOY HAS HARMONIC BALANCERS IN ITS ENGINE TO REDUCE VIBRATION. IT IS CALLED AN 88B ENGINE AND IS SMOOTHER IDLING THAN A RUBBER MOUNT. ALL SOFTTAILS HAVE THE 88B ENGINE BUT ARE RIGID MOUNTED TO THE FRAME AS OPPOSED TO RUBBER MOUNTED LIKE THE TOURING BIKES AND OTHER FAMILY BIKES. THE HARMONIC BALANCER BY THE WAY ZAPPS ONE HALF HORSEPOWER TO RUN. JUST THOUGHT YOU MAY WANT TO KNOW THAT LITTLE TID BIT.

 

Great feedback guys...I've been asked countless times why my bike jumps more than others...

Put it in plain english as well.

Thanks.

 

WOW!!! You guys are the best. That's good to know and makes me feel much better.

 

Yes, they nailed it re: the differences between the 88A and the 88B.

I've owned both. The smoothness of the 88A is nice, but almost too smooth in my opinion. I really dig the slow speed/idle vibration on the 88B in my bagger, and it smooths out at speed anyways, so its not an issue once your're cruising. Plus, the ole lady loves the vibration when we are sitting at a stop light

 

All of the above threads are correct but I would like to add that if you are feeling excessive vibration once under way I would suggest you have your dealer replace your front motor mount with the new type. Check out the thread on motor mount recall. My SG is in the shop now for that very reason.

 

I'm pretty sure you have that backwards, the b engine is in the softails.

 

you'd be correct...B=Balanced. more moving partz to break IMO...
