Waveblasting my life away
I recently put a new factory mod pipe on my blaster. and i started out with the recommended jetting and it was running great. but I am not getting any color on my plugs. I turned the top speed screw out all the way and i can't get it to run crappy or get any color on the plugs. So ive been trying every bigger size to get some color on the plugs. currently i hvae tried 6 different bigger jets and it still is running good and the color on the plugs is getting better, but still not dark like i want them. I know something is not right. cause im running a 160 when they recommend 145. thats a huge jump. I don't know what the deal is
