What is a web cam and what does it do for a 400ex. Where could i get one and are they worth gettin. Thanks

 

If you get the web cam 450/451, save your money and go to servicehonda.com and order a 2000 xr400 camshaft. It is the same thing for $115 WITH NO CORE CHARGE. I put one in but I also put in a 416 10.8 to 1 piston also. I could tell a difference, but I did both things, not just the one. A cam usually changes where the power hits in the rpm range and also determines how much or how long through the power range. The xr cam makes more power at higher rpms as opposed to the stocker which makes more power at lower rpms.
