I'm not overly concerned because Jens seems like a totally solid guy that stands behind his product. So even if I chose to remove it it would not be a big deal.

I was just wondering if anyone else can get their bike to "bog down" with wide open throttle when cold?
If you have or can borrow a GS-911 to creat a log file, it would be easy to see what is going on. Below is an example of a problem I'm chasing on my bike. The AFR reads lean for he first 10 seconds after ignition. And the spark advance plot shows that the rpm is building slower than normal and the advance is coming in later than normal. The data doesn't say what to replace but it did point me in the right direction.

I tend to agree with you. 2-3 minutes of riding moderately is better for the engine.
