I have owned two R1s, a CBR 1000 (current model), Hyabuasa, Speed Triple and I wanted a bike that was fast and comfortable.
1. The Super Duke I bought is 100% stock. The engine seems really corked up. What is recommended?
2. Bike is not as fast as I had anticipated. See #1.

Thanks!
David

Comrade the search button is your best friend. Here's a start:

Welcome!

As Jmann suggested do a bit of searching first (soul and Superduke )
Most of your questions have been answered plenty of times before, but if in doubt always ask!

No doubt this has been asked many times, I tried searching and didn't find what is likely there.
And search suggestions or thread recommendations would be appreciated.
