Hey guys, After riding 2-strokes for years I decided to see what all the hype was about and bought a 2007 yz450f which is my first four stroke. I took it out riding a few times (mainly just big open putt around areas) but last week I took it to a pretty technical ORV park. After riding for a few hours I completely burned up the clutch on a steep trail. The trail was pretty steep but I have done steeper trails than this on 2-stroke bikes before and never had any issues or problems. I bought a replacement clutch kit and took it to the shop to make sure I didn't do more damage but now I am a bit paranoid that I'll burn it up again! Are overheating clutches a common problem on four strokes?? Should I switch the stock sprockets (13/49) to a 13/52? Would appreciate any advice, comments, and/or tips you could provide!
