Well, the top of the engine is easy to reach that's true, as is the top of the carb. Overall, though, the carb is a real PITA to access. It sits right between those frame rails and it wants more delicate hands than mine to reach in there. Sigh.
The bigger frustration, as far as I'm concerned, is that frame design makes it dern near impossible to swap on a larger tank. Almost all tanks around are meant for a conventional backbone type frame or are fit very specifically for some other frame rail dimensions. And at 0.8 gallon capacity, that tank REALLY needs to be changed out.
Well, I don't know exactly how fast I'm going, and I don't know what RPMs its turning. It just feels and sounds like its really wound out in 5th and I'm not really going that fast thru the neighborhood. And second gear is barely above walking speed!
Interesting about the possibility of a cat. It never occurred to me to look or check. Huh.
