I did a search and found out that the yfz450 quad exhaust cam is halfway between the yz and wr timing. My dad has his stock yfz cams and I'm gonna throw the cam in there tommorow afternoon. I already have a full pipe, airfilter, my own custom ais plugs and am looking for a little bit more snap (I think the yz cam will just tire me out). Do you guys think I will run into any problems? Any help will be greatly appreciated. Also my left fork seal just popped. What seals should I get? Stock? Thank you.
