Rusty case sounds like a nice drive! Cool pic. I am using some non slinging chain lube it has been good stuff can't remember the brand name tho.
I don't race or compete I just like hot rods. For me at the moment its like when you buy a cordless drill set. When playing the perfect chess move move ya buy the same kit again if'n it works for ya. Means more service usable parts in the long run lol.
I keep thinking about these four strokes but I already got this drill kit lol.
Mebbe next year I can get around to trying one. I had a few HT's already they are good motors is what ya make of them tho. Can't compare to the M. IMHO.
