Ok i tore the whole motor down to cracking the cases and put in a crank i got out of a 2006 300ex because my rod bearings were boned. I put it all back togeather and started it up and it sounds great but when i try to shift it into gear its really hard to push down into first and it stalls instantly when i shift it down. We tryed pushing it and dropping it into first and i rode it around for a while with the clutch pulled so im guessing the clutch it stuck. What should i do from here?

Are you saying that it's moving with the clutch lever pulled in? If so, then it sounds like you have put your clutch or clutch linkage back in wrong. You didn't leave the lifter piece that disengages the clutch out of the side cover, did you?

Didnt mess with any of the gears you need to be a rocket scientist to do that according to the book lol. I was looking at it and was like WHAT??? Anyways yeah i hope its just the clutch ill talk to helmut. Oh and another thing my &#^%ing rockers are tapping again! :icon_ nono2: when the oil pump went they took some damage but we buffed them with 000 steal whoel or however you spell it and then we used some like supper fine sand paper and the scoar marks came out pretty good? hoping the valves just need adjusted who knows?

I left all that stuff in the side cover cuz i figured i shouldnt mess with it. But my clutch was slipping right before it blew up?

Yeah seems like you have a good bit of problems with the rockers in that.

Yeah they would have been fine probably if the oil pump hadnt gone bad before but i put a new one in and checked it before we put the valve cover back on and it was pumping.

That round piece just sits in there and can fall out easy. It may have fallen out when you put the cover back on. Anyway, if the 4-wheeler moves with the clutch lever pulled in, I would take the clutch bolts and springs back off and take the clutch discs out and then put them back in again. Sometimes the clutch discs, clutch center, and the pressure plate don't go all the way in like they're supposed to. They get caught on one of those notches and don't bottom out. I've seen them do that a lot. Also, make sure the bearing is in the center of the lifter plate on the front of the clutch when you get it all back together. The bearing is what that lifter piece pushes against to disengage the clutches. If either is not in place, the clutches won't disengage.

Alright ill probably get a chance to pull the side cover off tomorrow and ill let you kno what i find out. Thanks alot man!

Oh yeah and i remember we struggled alot with that side cover because i cant get the reverse release off of the side cover so the lifter piece probably fell out while we were struggling with that. If i had to guess. But while im here are the valves on 300ex's always a huge pain in the ass or am i alone with this problem?

I don't think I've ever had any problems with the valves on the 300EX.

Adjust the valves and trying to get the ticking out is always a pain in the rear. I know it is with mine.

Well, maybe not. Moose says his is a pain to get the ticking out. I don't ever have a problem with valves on any kind of 4-wheeler. Man, I must be doing something right. Uh oh, I probably shouldn't have said that. Now, I'll start having problems with every one that I work on. LOL.
