I'm going to give it a few tanks of gas to assess it some more. To be honest it used to bog down a little without the booster plug when cold and I may be trying too hard to find a fault with it.
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?
