kawi calls for moly there b/c of its high heat resistance, +1500?F. My tube came from Honda
ask for it at the red dealer, u can recognize moly by its very distinct odor.
My personal opinion would be to do it right the first time with factory specified lubricants, but as mentioned, after running awhile the exhaust spooge of burnt 2stroke oil lubes some. They told you to just use BR grease, b/c thats what they had available to sell you. 4oz tube of moly might cost as much as two, 1lb tubs of the blue stuff. I guess bottom line.....the wrong grease is better than none at all
