2000 Polaris Sportsman 90

[ltnitemechanic]

I have a 2000 sportsman 90 with fresh gas and a clean carb. This machine starts great idles perfect and will run for about 500 ft then boggs as if it is running out of fuel. but the carb bowl is full and it will still idle but will not pull or accelerate. When switched off and it sits for a while the same thing happens it runs great then boggs. could this be electrical? if so where do i start?

It could be electrical, if it were an ignition problem, a faulty CDI is most likely to cause a problem like that. You could also be dealing with an air leak. That could be in the intake or a bad stator side crank seal. Another though is that the float bowl vent tube could be clogged, the float bowl will still fill up, just not as fast as needed to keep the carb supplied with fuel.

ltnitemechanic - were you able to determine the problem? Our 2000 90 is doing something very similar.....idles fine but cuts out when you give it throttle.....

Thanks.

check all the electrical connections and make shure they are not corroded ... this is a problem with alot of polaris quads ...
