get pipes for sure, K&N air filter,NOSS COOL HEAD 20cc or 19cc domes any smaller and you may create problems with your crank it is 2 piece and may come apart with to much compression, reeds well I did not really notice a difference with reeds. 13 tooth front sprocket is a good thing I liked the difference that made. I also might add that tires seem to be very very very important these banshees make so much power so fast that tires don't have a chance to grab anything. so good luck have fun buying mods it is a blast man. Loccogato on here seems to have a good knowledge base with tires he is into hill climbs and shit he can help you get the right set it sounds like he has tried them all or seen then in action anyway
