Gearing

What type of gearing are you guys running flat sand drags. Got some head work from Ron woods dual pipes high comp piston and 22in 10 cup paddles. I know it’s different with each wheeler. But I couldn’t seem to really pull away from 450s today. I can’t start in second because it likes to sputter in second gear till I feather it out. Just trying to get a ballpark front and rear sprocket set up. 1st gear was pretty much useless had to shot out of it right away.
