My neighbor got a yoshi slip on for his predator and I want to make sure that the bike is jetted right. When I put his knn in I rejetted to a 155 and left everything else stock. We are at 2700 feet and the temp is 100s. The main jet is a 155, pilot is stock and the air screw is stock. What should I do? thanks, daniel

When we installed an HMF s/o on my buddies Predators with drop in K&N filters we just changed the main jet to a 155 and they run great.

I bought a jet kit and i am 300 feet and below so i ran a 150 and 2nd on clip and 3 out on air screw and now it is really doggy. But if i put air screw on 2 out it has al sorts of power but gets hot but the light dont come on tho so i think ill go up a jet.
