Hi Jason..

I had exact same problem.. bottom line I had to replace selector forks (all three) and second gear cog.. If u do replace a gear cog then please take a tip from me (lesson hard learn't). Have all your gears undercut at the same time or it will slip out of another gear.. I got my bike back after 2 nd gear done and on the same day 3 rd gear started to slip. Had to send bike back and have all the cogs undercut... Now its fine.

And yes u do need to remove motor to open gearbox and u will need to replace gaskets..

You have a bent shift fork not engaging the slider gear properly into 1st gear. The engine will need to come out of the bike. Remove the top end, the flywheel and electrics, the clutch, shift mechanism and kick starter and a few other parts. THEN you are ready to split the gearbox to get to the crankshaft, gears and shift forks.

You will need an impact driver, flywheel puller, case splitter, torque wrench and factory service manual, plus the normal screwdriver, pliers, etc.. Alternate to the special tools is taking it to the dealer and say "Fix it". I normally tell people to take it to the shop just so they don't get into such an involved project and they have a knowing eye working on the engine.
