Keep at it you have a long way to go till she drops.
As far as the VP goes, I run the 25% VP Powermaster and I really like it. The race blend will render more power but you also are taking out a good percentage of oil. A lot of people I've talked to run the 25% VP with an ounce or two of Klotz Benol. I run the castor oil in the VP as well. Little castor oil adds a safety net. Id start with 2 oz if you are newer to tuning to add a little safety net in case we go a little too lean, or if you are comfortable with tuning try 1 oz.
Got about 5 more tanks through it. Leaning It out little by little because as you stated it started to go rich. I think the JP2 pipe is holding me back and wanted to know what you thought about the 41019c with the 9886. Right now I am more interested in speed and just having fun. Also it came with 8 mm insert installed. If I went bigger it would give me more power up top but with less tq correct?
