Oh yeah, I had a dream last night that I was out riding and I realized I had carelessly forgotten to install the oil tube that goes from the oil pump to the head and that I was trying to get home and was getting really edgy because of the sounds my cam was making, starving for oil in there. Then I looked down there again and either the primary carb, or maybe just the airbox boot, was missing from the engine too. I thought "so that's why I've been having crappy idle". In real life the holes for the oil tube would have been shooting out a stream of oil and the bike would not have run at all without a primary carb! I have some wierd dreams, I know.
