ok well i did some research but i really dont know anything about this so. I know the stock size is 15-40 and stock chain is 525. I allso know that i want sprocket specialist sprockets and either RK or DID chain. Well my question is how many teeth should i get for the front and rear. I want larger rear and smaller front for better accelaration. I allso want a size that wont wear fast like the 520 kits. So if anyone can give me some help on this topic anything would be great thanks alot.
