I was wondering if I can do the 450 cam mod to my 99 yz400 or would it be better to just get a set of hotcams. If so can someone give me the details on it or refer me to the right site, because I know the question has been asked and debated over a million times. Thanks

The teeth are ever-so-slightly different on the 450 cam compared to your stock cam.

So far, there has NEVER been ANY issues w/ this swap, with MANY, MANY bikes.

Some guys didn't want to take any chances and went w/ the Hot Cams. The HC is more expensive...but you will have to make the final decision.
