94 artic cat zr580,wont move revs up to 4500rpm, idles have bypassed all switches,new primary coil,

coil you can test if you have a coil tester but doubt you do. CDI cant be tested. could also be a pick up coil on the stator, ignition switch, kill switch, tether if it has one.

blocked main jet or low fuel pressure if injectored

Bad Cat, bad coils, Bad fuel pump modulator or bad fuel pump (weak). These are places to start checking. My money is on a weak fuel pump.

It is not getting fuel from the reserve tank for some reason. check for a blockage some where , may be a fuel filter.

Might be the gear box if the higher gear is has any problem it may be causng the boggs

Does your artic cat have a carb cable if so it will have an adjustment or a clamp on the cable where it attaches to the linkage..check make sure it is set to low idle..and your idle screw is adjusted to low idke..meaning cable adjusted to lowest possible position when the throttle is released..then make your final adjustment using you idle screw..good luck

You can get a new ignition switch.

Bypass your ignition switch , kill switch, and carburetor safety switches(on the side of the carburetors). All common problems for older sleds (stopping spark). In the carburetors the magnets inside the slides come off killing the spark. There is a kill switch bypass wire in most arctic tool kits. Ignition switches are notorious for going bad and are easily bypassed by simply unplugging them.

i have a 1999 zr 700 runs great untill it accelerates, then it boggs out. it will idle great.

I have a 1995 artic cat zr580 efi oi only gets up to 70 mph it has nep plugs, new drive belt gas filter and a brand new battery I took it upstate new york (old forge) was left behind by my riding buddies I hear that there is a chip for the EFI that wears out is this true
