This one does seem to be shifting hard I'm just turning the sprocket and moving through the gears but it still feels very clunky and tight. I'd bet they were using regular motor oil and not oil for wet clutches. The kicker doesn't grab everytime either. I think I'm gonna have my hands full with this build so I'm gonna redo everything.

While I'm in there what all should I replace? Seals, bearings etc

I picked up a Banshee that is a basket case. I started looking at all the parts I'm going to need and I noticed the front sprocket is welded on and not even a good job at welding it so I have to change the shaft out. I've been looking online and I'm not finding any guides on this. Do I have to split the case to change out this shaft? I have a locked up yz250 motor I'm going to experiment with before tearing into this Banshee motor. I've never taken the bottom end of one of these apart so any guides or videos would be a big help.
