Finally topped out the Prairie!
After doing the camshaft redegree(Thanks Steve!), and the dial a jet, I got on a stretch of pavement yesterday, and did 69 MPH, with a slight tailwind, and 65 with a slight headwind. With the redgreeing of the cam, I lost a little off of the low end, but the midrange and top end are awesome. The midrange throttle response is RIGHT NOW! I was doing 55 on a slightly curved dirt road, punched it, and went into a powerslide! Man, I love this thing, and I can't wait to put the timing key, and My Supertrapp on! I can't imagine what the power would be like with CDI, aftermarket cams, or a big bore kit[img]i/expressions/face-icon-small-shocked.gif[/img]

Had about the same ride myself today. Testing a 785 uphill around one corner I had to get out of it because it went sideways. I hit the top of the hill at 69mph when it hit the rev-limiter. I don't think we should go this fast on these atvs. Going across the 200 foot parking lot it hits 50mph real fast but it needs more breaking power.

That puts glad on my face!

Velocity: 69 MPH = 101.2 Feet/Sec
Mass: 600lb ATV + 200lb Rider = 800lb
Kinetic Energy: 172,630 Joules or 127,325 ftlb of kinetic energy.
In other words 69 mph to 0 mph requires burning off quite a bit of energy either through friction (brakes) or impact (splat). Most rifle bullets are in the 1,000 to 2,000 ftlb of energy range.

Another thought - in the 0.5 sec you spend glancing at the tach or other do-dad you traveled 50'. In the 0.2 of sec it takes you to react to something, you've traveled 20.24'.
