The intake boots on our 1998 zr 500 are cracked pretty bad, my brother said since more air is getting in, there is more gas too. Can this be true?

its just that the pistons are too clean with little to no carbon on them at all. we aren't sure if it is too rich or too lean. after reading about piston wash on the internet, clean pistons could mean both depending if the cylinder is wet or not when you take the engine apart. we're kinda confused.

ya i got that...but looking at the piston wash, from what i can find on the net it looks like it is running rich... just trying to figure out whats going on. carbs are clean, but we found the wires on the right carb were shorting. and the vent lines were plugged. taking care of that and hopefully the sled will run good. any other ideas?
