"First ride out was at Hollister Hills in California. Elevation ranged from 600ft - 2,500ft. The bike starts FIRST kick always, which is awesome. The bike had no idling issues when I would have the clutch in or while it was warming up before the ride. When I first rode the bike onto the track to get warmed up I instantly noticed how much more crisp and how much earlier the power came on from the bottom compared to my TMX and Keihen PWK Airstryker Carb. The power delivery became somewhat less explosive and unpredictable and much more useable and smooth. My lap times were cut down a few seconds a lap because of how much smoother the power delivery was. So instant bottom, smoother transition the mid hit and the overrev up top was noticeably longer and stronger than either of the two other carbs. After some time on the track I went out for some singletrack loops to see how the low end would work out on the tight stuff. There was no longer a hesitation or slight sputter as I was rolling through the tight technical trails in 1st and 2nd gear. Clutching become a little less necessary since there was not as intense of lurching going on when the bike was in low rpm's on super tight sections."
