Rev bombing, I can see it being an Olympic event in the next summer games....Got to be a real good thing for the engine internals.......
As usual my initial tear down is proving interesting. Of course there was no washer in the oil filter, one of these days I am going to find one, kind of like that three legged one balled unicorn, got to be one out there somewhere. The carb jetting was quite interesting, I believe I have found why the old pugs were black. 086 carbs with 140 mains, 40 slow, needle clip in the very bottom groove, and at least 2 to 2 1/2 turns out on all four on the mixture screw. The old headers were quite open but did have some baffling, but still a little overkill IMHO considering the stock air box was still in place. To prove how resilient these old work horses are, the damn thing still ran pretty good. Since I am going back to a complete stock exhaust, without the useless baffles, I might go with 107 mains instead of 105's to begin with, just for a little extra juice. I am also going to start sanding on the white frame this week, I really hope no one objects........
