In comparing the other makes to the YZ, it seems that the YZ's mid pipe is the closest to both the carb and rear shock reservoir. I put some heat shield between my pipe and float bowl, and it seemed to help. What about the shock reservoir? They even have a nice little sticker from the factory stating how not to expose to heat/flames!!! yet, the pipe gets pretty hot and the reservoir practically sits on it? Does this compromise the performance of the shock? In looking at the new CR, they even come w/ the "shorty" reservoir similar to the pro bikes, keeping it well above the pipe.
