i need help with jetting on my Yamaha warrior. I have just rebuilt it and I have put on a k and n air filter with the airbox mod, a gytr slip on, and a .040 over 10.25:1 wiseco piston. and my elevation where I ride is around 1000-1200 ft. could anybody tell me what jet sizes I should use?

 

I found this on DynoJet's website: http://www.dynojet.com/pdf/q406.pdf. Looks like you will need a 136 main jet for your setup.
