Also, only the right side 4wd works. The left side is stiff. I just repacked the grease. I readjusted the cv joint and it worked for another min but when I switched it back to 2wd and back to 4wd it wouldn't work. Any ideas?

Looks like shift fork bases might be broken off.

That's what I thought but it shifts fine. I only took the front cover off. I pulled the pull start and the gears go the correct direction. I guess since there's an automatic clutch, hand turning the wheels wasn't working. But it goes the correct direction. Those pins were found in the front case on the bottom. I was thinking, it looks like the case material but haven't put it next to a magnet yet to find out. 

So I have a 2003 (I believe) Honda trx450s. Bought from someone who potentially crashed it a few years ago. After his crash, the atv could only drive in reverse. He drove in reverse home, parked it and left it sitting for those years. I found oil in the air box and a loose foot shifter. I opened the crankcase and found 2 small silver tabs on the bottom. It looked like it sheared off something.  I repositioned the shifter. The plate cam clutch was off the clutch lever. We didn't get too far yet but the small pins look like that star shifter thing. I was hoping we could do the work without pulling the engine. Now the gears are totally in reverse. All the way down is Neutral. But when you try put it in reverse, it goes forward and the reverse light turns in. Then upshift (US) is neutral. Neutral light turns in. But then when you US again, you actually get all the 5 gears but all those gears are in reverse. The whole thing is backwards. Any thoughts? We think the oil in the air box was due to a rollover hopefully. Tested head and it fires up. Any assistance is appreciated...
