Rockero Posted April 17, 2010 Report Share Posted April 17, 2010 I am trying to get the quads allowed on the 1/4 asphalt track. The owner wants to see us running the strip before allowing us. What gearing and tires will be good for the 1/4 mile? My banshee got stock chassis, +6 swing arm, 3.5" forward a-arms, 421 long rod cub, 38 mikunis. All your help will be appreciated.

lowriderb Posted April 17, 2010 Report Share Posted April 17, 2010 I am trying to get the quads allowed on the 1/4 asphalt track. The owner wants to see us running the strip before allowing us. What gearing and tires will be good for the 1/4 mile? My banshee got stock chassis, +6 swing arm, 3.5" forward a-arms, 421 long rod cub, 38 mikunis. All your help will be appreciated. what primary gears are you running? and what axle, with what sprocket hub (banshee/honda), what size tires? stock primaries, i think people are running like 18/39-40, 2.81 primaries would be like a 17/39-40, 2.63/2.36 primaries would be different ext that would also depend on the sprocket hub if you have a drag axle with a honda hub you can get down to like a 33 rear sprocket. the tire sizes would probably be a 20x8x10 tire i would guess, but there are tall and shorter tires out there too..

Rollout is 63" weighs 10lbs. Don't go bigger then that tire size. Sprocket ratio 2:12, 2:11, 2:10 for 1/4 mile with a 6 speed tranny. If you need more help on setups for 1/4 mile. Let me know. My motor is a DM 557cc 10mm with 74.50mm bore. 141hp on alky. I use the AM 20/8/10GT tires. I have been racing 1/4 mile on a Banshee since 1991. I got American Racer tire at dealer cost for the atv asphalt draggers. Quote Link to comment Share on other sites More sharing options...
