Wow! Looks like fun!
I wanna get me a dyno and have fun too!
How much does one of them go for?
Roy, get your ass to Topeka this weekend. lol The club is paying for it and you'll get multiple runs with a sniffer.
Every dyno pull I have made has always been 1 gear lower than your top.
6 speed tranny= dyno it in 5th
5 speed tranny= dyno it in 4th
4 speed harley= dont waste your time or take time away from the VMAX riders wanting to tune there bikes.:rofl_200:
You are correct that it's best to do a pull in the gear that is closest to 1:1
but think about this - you have changed the trans ratio but what are you going to do about the rear differential? If you change the rear diff from a 3.08 to a 4.56 do you think it will make a huge difference in the dyno readings?

What change in gearing was made to see that much difference? Was it on the same day? If not it's not 100% valid. Last years dyno session was down 4-5 hp for everyone including bikes that had no changes from the previous year.
