hello,
i have a 1997 500 xplorer .
it will ideal fine you go wide open and its lazy and spiting fuel out of carb.
if i install the air box it runs worse .
things that have been checked or replaced
cam is in new condition
valves adjusted
carb replaced
new gas
fuel lines cleaned out
new coil and plug
seems like the ignition timing is retarded
sometimes its hard to start
any help would be great .
thanks
