I see this web site is still here. One of my last post was for upgrading my 01 scrammy. I finally got down and dirty and did some mods. I replace the factory helix and replaced it with a roller stye clutch and replace the factory spring to a violet spring. Man what a difference. After that I replace the rear shock since I popped my last one from a 9 foot jump. Even more of a difference. Then bumped the carb from a 40 mm to a 42 mm. Never been on a quad that not only stands up. But, stands up and spins on pavement at the same time. Definently one of those times you don't wont to catch traction. Now its time for the next step. Replacing the tires now after I done smoked the hell out of them, Get the front wheels realingned after replace the tierod ends and find a way to get more top end out of it with out killing my bottom end.

Oh yea, this is a 01 scrammy 500HO 2X4

 

yep, forum is still here. sounds like your going to have a very good going scram when your done. what about a small sproket change to get a little more longer legs w/out going to extremly and loosing all the low end. just a thought.
