What can i do to make my stock banshee faster than a friends yfz450 he has a minus 6 flywheel, 470 big bore kit, port and polish, LRD full system, and a air box eliminator. And i dont want to spend to much money.

 

get pipes, keyway, boost bottle, cool head, and bigger sprocket in front not to much bigger like 2 teeth or 3

 

without spending too much money? ummm ya impossible

 

get toomey t5 or cpi pipes, coolheads with 19cc domes (race gas only), adjustable timing plate, k&n filter, 15 tooth front sprocket.

also get rid of the stock tires due to its lack of traction.

if u have more $$$, recommend porting, forged pistons and getting crank welded for reliability specially when using the 19cc domes.
