I am sure you have been on the FJ forum, but i will add my $.02 worth for proper lube after running almost 100k on a few ST1100/1300's. I have heard many people besides just Honda people raving about the Honda Molybdenum Disulfide lube as being some of the best on the market for longevity of splines and their wear. It sticks to it awesome, and adding a liberal amount is always best for them. There has never been anything wrong with adding extra, then a few miles later seeing it coming out of the cracks. Better too much than not enough. Yamaha owners may be a little different whining though.
I can bring the Fork Oil if you want to change your oil. That way it is free. I also have the big allen tool.
PM me the address please.
