I am currently doing this because mine slips out of second gear and I developed a leak between the cases. Remove the exhaust and then remove the engine from the bike. You're going to have to remove the oil cooler, both left and right covers, and the oil pan. Afterwards, you need to remove the clutch basket and all the mechanisms behind it. You will need to remove the magneto and you can do this by using the big threaded engine hanger collar to back off the magneto. Lastly, remove the speedo sensor on the top of the tranny. Now you're ready to remove the bolts from the top and bottom of the engine. You don't have to remove the head from the upper case. I am building a horizontal case splitter so that I can split the cases without damaging the case surfaces.

If you are good with mechanical work and have a manual to help you along its possible, but yes you are going to strip the motor off the bike and split the bottom case. If you are going to do it you should inspect the clutch or just replace it too since your there. If you want a shop to do it, expect to pay alot more than just buying another motor.

thanks, i was really looking into doing it myself, i have the manual to help, i was just wondering if i needed to mess with cam timing, or anything that will kill the engine.?
so to someone that kinda knows his way around an engine, how much time will i expect to change the transmission with the engine on the table?

Well no you do not have to mess with the timing, now you will have to remove the timing bracket that takes out the slack on the chain. As far as time goes I would not worry about how fast you can do it, more of take your time and make sure you do it right. Take pics of cables electrical etc to help put it back together. GL!
