I have been told by several memembers to let more air in my box.I didn't want to do this but when a friend with a new 450r came by he convinced me.He bought the HRC kit for his 450r and said it was the best mod for the $.We went online and he showed me the airbox lid,heck 1/2 of it is missing.We came up with a great way of doing it.Hope this helps me get my jetting right.I will post pics when it's done.Going with the factory snorkle and 1 added snorkle.

Or should I go with 2 snorkles the same size,and should the baffle behind the factorysnorkle be removed
