I recently did an airbox decap following the pics in the sticky, and it turned out looking just like it, sounds great, runs great..... at lower speeds. Once I get the up to about 55 or 60, the bike starts hesitating and trying to stall. I have an adjustable needle with the clip on the second from the bottom, and my a/f is almost 3 1/2 turns out (it was only getting to about 45 with 2 1/2 turns). I have stock pipes drilled to the second baffle. The main jet is a 195. Do I need to go larger, or did I cut the airbox wrong? I have a new stock airbox on the way and I am thinking of going back to just stock.
