I recently bought a really cheap clean 2003 WR450F, I knew it had issues when I got it, but I thought the issues where not too serious. Now I'm not too sure.
It has the common starter/woodruff issue, and with this one, the kickback blew out the one-way starter bearing on the crank. Not a problem, I removed the starter gears, diconnected the starter and use the kick.
The issue that I am worried about is: It is very difficult to shift. Neutral is pratically impossible to find, running or not, clutch or power shifting, rolling or standing still. When trying to shift without it running the lever goes up and won't return, if you work the lever it eventually returns but doesn't always shift. I even removed the clutch to make sure it wasn't causing the issue. It will shift when driving at the proper rpms but it does take some force to get it in. Everything on the exterior looks fine.
My fear is that someone might have split the engine cases at one time and reassembled the tranny incorrectly. I'm not really excited about have to tear it completely down. I just want to ride!
If anyone has any ideas please let me know,
