You should still pull the rea rwheel and relube the splines. It's critical that they stay lubed or it's money spending time.
It's also way past time to replace the clutch and brake fluid. If it's the color of honey, which it probably is, time for a change.
Replace the rear end lube as well. There isn't much in there and it needs to be changed frequently.
Last but not least get some silicate free antifreeze and flush the cooling system.
Then......get your motor running and ride.
