Well heres the details, i have a 2001 yz426f, and today for some reason in 5th it slips like the clutch is gone, and it dont seem as snappy , almost like the clutch is gone, my buddys yz250 lost the clutch and done the same thing, and when driving it , it smelled like hte clutch was burning, im not new to ripping apart engines, but i am new to loosing a clutch, ive never ever lost one.So my question is , can it be the clutch or is my 5th gear tore out? I havent had a chance to tear it apart and inspect the clutch , but i am just wondering if it may just be the clutch, because im realy not liking the idea of maybe having to ripp apart my whole engine :thumbsup::thumbsup:

I would say it's time to split the cases and check the gears and shift forks.
I think it's pretty common on the 01's. On my 01 I had to replace every gear but first and all the shift forks. I got in the bad habit of shifting without the clutch back when I raced 500 two strokes and believe that was a factor:bonk: Clutch? What clutch? I was just trying to hang on:crazy:

426 boy is on the money. It if it only does it in 5th gear then it is the selector fork. A buddy of mine had the same problem. Also not too uncommmon.

First Make sure there is no tension on your clutch cable; Bends in line, ect. If the cable is fine pull the right case cover and take of a clutch spring and see if it is proper length. Usually the clutch springs go before the clutch disks. They are sold as a kit and its best to replace entire clutch at one. Less than $100.
The highest gear will show clutch slippage first because that is were the most torque is on the engine and clutch.
