Hi Guys, i have just picked up my new YZ450. I have spent two days breaking it in. The first day i rode it for about 2 hours very mild'ly. The second day was about 5 hours with a bit more challanging terain. The bike goes very well but im a little concerned about the amount of clutch fade i get when the bike gets fairly hot or the clutch gets used hevily like up a long windy rock hill climb. After it cools down it returns to normal. Has anyone else experienced this? I am doing a full service now that it has run in, maybe the oil change will help? My last bike was an 02 426 and that clutch could take a lot of abbuse.
