Hey guys and gals how is it going? I recently purchased a 2001 YFZ 426 has a ton of aftermarket parts on it, except for the 450 mod. I have only ridden the bike once since owning it, a month now. After kicking and kicking the bike I started to research some and noticed the all mighty "450 mod". Seems like from looking around 2003-2005 more bottom end and 2006 up better top end. I plan to go with the 2003-2005 cam. As bike has plenty of top end for me. Now the problem is seems like most post about it are a year old or so and information is kinda of scattered here and there. I plan on doing it myself as seems easy as most folks said. Plus I am mechanically inclinded and like to work on my own toys. Now comes my quesition what cam will work? A stock 2003-2005 YFZ450 cam? Anything else needed other then the cam, feeler gauges, and basic tools to do the job? The bike has 10 hours on it since was rebuild by the guy I bought it from. So do not think, scratch that hope it does not need anything else, LOL. Can some one just confirm what I need and where to find the PDF file or instructions on the install from start to finish? Thanks!
