Graves velocity stacks and non o-ring chain

Just before Monday's track day at Summit Point, WV, I put on a non o-ring chain and aluminum sprocket and also installed Graves velocity stacks (non tuning configuration). I did feel like the bike did have more pull out of corners and was able to accelerate more quickly. For the 400 I thought this was an improvement.

I think I noticed a little more pull on the uphill portion of the track that was a little lacking on the previous track day there in April.
