i have a 400 scrambler 01' all stock but a k&n filter added. curious what recommendations anyone has as to the next inexpensve mod i should do. i ride alot in the woods and some down at the sand. thanks for help!!!!
Before my buddy piped his Tblzr 400, I got him a Polaris violet primary spring. It perked the quad up a lot and allowed it to hit when the power band kicked in instead of several 100 rpm before it.
That's what we did. His stock spring seemed to let the quad engage several 100 rpm before the stock pipe developed any useful power. That's when I got him the violet spring. It made good use of the powerband on the stock pipe. Plus it only cost $20.
