Bike runs fine after taking off, just wondering if anyone else experienced the engine knocking at idle. I went through the compensator issue and the pinging on my 09 SG and 11 UL, but this is way different. I have 17,500 on it and haven't taken it to the shop for this yet.

 

There is a Rushmore dedicated forum, where you should get a wider audience, it's part of the Touring forum. I see a visit to your dealer, in your tea leaves!

 

not so much at idle but after the engine is hot and sitting at idle and goosing the throttle and also under passing acceleration in 5th and 6th gear... freaking me out

 

You know that seems so much like the knock I had in my 2010 screaming Eagle Ultra. I've rebuilt engines in the past and are familiar with engine sounds and I was determined that I had fairly severe piston slap a different rpm's. However after changing the compensator do too loud noises at start up that completely took away that piston slap sound. I would've never believed what I was hearing was the compensator at those RPMs and not piston slap due to the fact that I had 80,000 miles on the engine

 

You are using gasoline with the correct octane level, yes?
