If your motor is apart polish the channels. For the shift forks a.d the shift forks their eels and run slick 50 though.  Best to use old clutch while the slick 500 is in the bottomend.  The bike wil shift like never before.  Sometimes to easy. I've seen bikes with atf run in the bottomend and if it makes a lot of hp or is run hard all the time u will have proublem.

DO what to the shift fork eels?

Polish the shift forks to take the sharp edge off. Sorry 7 day in a row and 12 hour days wear me out.

Everyone is entitled to their opinion on running ATF in their gearbox. If someone is happy with the performance of ATF in their gearbox, and they have had good success with reliability, then they should keep using it.

The perspective I take on running ATF is that it has been around long before the KX500 came along, and if the engineers that designed these transmissions would've thought that there was any advantage to running ATF, I would think they would've recommended it. Additionally if running ATF in the KX500 would increase the mean time between failures, I'm sure the factory race teams would've run this in the bikes racing the Baja 1000. A professional racer racing these bikes in the heat for a 1000 miles is tough on parts, and most peoples machine will never endure these conditions. With the racing community I used to be involved with it was common practice for a lot of us to race two to three times a month, some months racking up 300 to 400 off road between practice and racing, and gearbox problems were extremely rare. I didn't know anyone running ATF.

No prob man, I knew there was something there. Was just trying to get it. I know how the long hours wear on a guy.

Read thru all this and I'm going to give the ATF a try. I'll post up my results

sniper1:
        I read all 9 pages and I see a lot of focus on cost but changing the atf everytime you ride even at $1.99 compared to the recommended oil changed every 4th or 5th ride seems like a push on a $10 quart of recommended oil.

        I have to ask how many factory teams are using atf because it seems that they would want the best in their machines as often as they are on the clutch.

        I just had to ask and am only asking because I never had any problems with a clutch or how smooth my bikes shifted and I've owned 2 K5s with no issues with my 3rd being picked up tomorrow so I am getting my ducks in a row on what is new and what is best in the world of K5s :)

        With all these oil changes one of these might be in order :) just kidding.
