Power vs. Speed
Hillclimb#42:
I have not had the opportunity to run anything on a dyno, but I have good friends that swear by them. During a recent "Dyno" conversation, one such buddy said that his bike made more power in 1st gear. Somehow, the dyno showed better numbers in 1st over 2nd, so he always gears the bike to suit pulling 1st gear. Most people hillclimb in 2nd gear, rarely having a shift and even more rare for someone to pull third out of the hole. This concept of one gear showing better numbers than another gear, confuses the crap out of me. I always thought, "a motor has this much power and the transmission is the equasion of a final drive ratio of the primary gear and sprockets."
Is it possible for a bike to have better dyno numbers in one gear over another, or is this a misconception or even a bad theory of reading the dyno power/torque numbers? I read on another thread about which gear the bike will be dyno'd in, and it got me wondering how that impacts the readings, and if it gives accurate ones with this variable....? Thanks again for the education.
Good:
The actual traction thing vs. what your bike can actually pull is huge. A few years ago we had a sand drags race here and the quad four stroke classes had everything from 8 paddle tires to like 16 paddle tires. The guy on the 8 paddle tire won that class overall. He got spanked by the unlimited Banshee winner in king of the hill though, but nonetheless, he was set up for that dune... Most "stock" quads pull best on an 8 paddle.
Later, I talked to the guy at skat-trak and even with almost 80 hp on the rear tire he still recommends a 10 cup paddle for the mighty KX5 in the sand, not 12 or 14 like some people think... Just food for thought.

i have 8 and 14 paddle paddles tires i think the 8 paddle turbo paddles hook up great my 14 scat track paddles seems okay for real low speed loose climbing

ive tried just about every paddle out there 8, 10, 12, 14, hookers, vipers, turbos and dominator.hillclimbing in loose conditions we use 14 paddle, viper on the 450, hooker on the 490, dominators on the 650 and 1000. in really hardpacked conditions we'll run a knobby, IRC M5B seens to work the best the terra flex has to stiff a sidewall.

You guys will get me dq'd, :lol: :lol: No paddles in Amatuer/Semi Pro Hillclimbing. Everything has to be originally a nobby tire. On the KDX I have a cut tire. Its a Budds Creek where I took all of the square nobbs off and left the rectangle bars. Basically removing every other row and leaving a tire with short paddles (sort of). This technique allows a little more spin right off the log. That allows you to pull a little taller gearing and still has some good hook up on the rough stuff at higher speeds. I won't have the same isuue getting the tire spinning with the 500, I'm sure. I was just fishing for some new ideas for adjustments. I guess the theories don't vary as much as I expected.
Here's the closest that I can get to paddle tires....
