Check out MMAD over on yfztech.com. He does awesome work and has his own custom cams. I have my head ported by him and his intake cam and my bike frickin rips. He builds mostly yfz's and that's it so he knows his stuff. He has his own custom cams that outperform the stock cams and all the others through the whole power range. The stock cams are very good and most are not better until you get over 8000 rpm's but you sacrifice low to mid range power and pick up more on the topend. His cams are 225 a piece, I am only running the intake cam because you're not gonna get much more power by doing the exhaust cam unless you're going big bore or stroking it. I run the exhaust cam in the modded position.
