Does anyone know the vavle lift for a stock 300EX? I saw that a Webcam's mildest cam is a .310 lift. I don't want to get radical with the motor, wanna keep reliability, is this cam a noticeable improvement? Thanks a bunch for any info!!!!

 

Mike, the Honda service manual doesn't show actual valve lift in the specs. page, just shows the total height of the lobe. I have read several posts on adding a cam to the 300EX and didn't see a negative word. The 300EX is 'under-cammed' from the factory and is well deserving of a cam change. Check around on here and the 'other' atv chatroom for more posts.
