I don't know where the link is, but essentially, it involves removing the battery, and removing the transmission screws. Put the engine up on blocks so you don't need the center stand.
Then you install a couple of the longest 8mm screws you can find(about 4"), one on each side so you can slide the transmission back about 3/4". Then, you can reach in with a long parts cleaning brush to put a little lube on the clutch splines. With the transmission in 5th, you can use the rear wheel to turn the shaft to get all the splines.
