Lately I've been seeing a lot of different posts about Sport and Scrambler 400's so I thought that I would post a video of me testing different primary springs at the local 1/8th mile dragstrip tonight.The Sport has a 20hp shot of Nitrous Oxide on it, but this pass was made on the motor with no nitrous.

I've found that by racing on the dragstrip and by comparing my 60', 330', 660' times and mph I can find out some valuable and accurate information about which parts work and what parts don't.I run a wheelie bar and Jr Dragster slicks on the Sport so that I can get consistent times and don't have to worry about wheelspin or wheelies.

Tonight I was comparing five different primary springs with my new Team Roller Secondary clutch.
