Raising the port timing to stock specs.
I removed the head and it looks great.

Well...
I had the wrong fuel in the bike so we only gained a couple of HP.
Going back on Friday with the correct fuel and I will bring a few extra parts to test as well.. 8-)

Going from VP C12 to 92 pump gas we lost .8hp :o
But... IS it worth it to pay 90 dollars for 5 gallons of C12 vs 20 dollars for 5 gallons of 92 pump gas?
I can tell you that the c12 burns nice and clean.
But for .8 at the rear wheel? :roll:

I have some numbers that I want to share but I have to wait until next week when the tech guy is in and have him print out a comparison graph...

All this testing and tuning is worthless without a good baseline..
