On the fork oil issue. I did some reseach a while back and came up with
this answer.
Bel-Ray High Performance Fork Oil 20W for all standard and all
cartridge-type motorcycle forks.
As I understand it, its 100% pure synthetic, doesn't foam up like mineral
spirts, extends seal life, and has special properties that reduce
"Stiction", and in a pinch, it tastes great too!
20W is supposed to be all around best weight to run with becasue anything
lighter or heavier can make the car ride to hard or soft.
I bought a one liter plastic bottle for $9 USD from a local Yamaha shop.
Pretty interesting look on the guys faces when I told them the specific
application.
Hope this helps.
