At Bike Week, I watched a dozen 1200's and not a one shook as rough as my 2006 Sportster 1200 Custom did. Motor mounts are fine, idle is where it should be, but it shakes worse than a old frame mount Sportster at idle. Once off the line, it is smooth as silk. Any ideas?

I actually love it and might run it that way till the motor falls off.

 

Check lower front motor mount at base of enginethat and the fact you have solid struts translates into more vibes overall is my guess.

 

Maybe set the idle up a few RPM

 

I'll bet your OL isn't going to be real happy if you solve the problem.......

 

i have the same bike with the mini apes,does the exact sme thing.mine shakes mostly at the end of the handlebars when i take my hands off.

 

So maybe it is just the apes? Need to find another sportster with apes and compare.
