2008 Sportsman. Why is it running rough?
The 20 Amp fuse (diagram shows only one 20A) feeds ignition coil and fuel pump circuits. With a current probe measure the two circuits separately to identify which is most probable cause.
Check battery voltage with engine running. It should be well over 13 VDC.
If it will run for a few minutes, you might get by with a touch test of the ignition coil and fuel pump. If one is markedly hot, the heat likely identifies the culprit. But a current probe is the tool necessary if you want to avoid part$ swapping.
Recommend fuel pressure check also. Eccessively high pressure could be problematic and low pressure would further implicate fuel pump.

2011 550efi quad. How can I adjust throttle cable?
This will depend on how much you need to adjust it. Small amounts can be made using the cable sleeve adjusters. At each end of the cable sleeve is a nut shaped connector. If there is a small thin nut slacken it a couple of turns. Wind the larger nut out to tighten it and In to slacken. Use a wrench, (spanner), to hold the large nut still and re-tighten the small nut to lock it. Some versions don't have the smaller lock nut so you just wind them in or out. If you need to move it a large amount it might be easier to just replace the whole cable.

Your engine codes should only be in two digit numbers and you should not have codes that end with any zeros.check engine light should flash like count the flashes three flashes pause then 6 flashes would be code 36 then longer pause between codes then you have more than one code after a long pause it may flash 4 times then short pause then two flashes would be code 42 witch is engine coolent temperature high voltage a code 56 is fuel pump open load/short to battery or short to ground should start with one flash short pause then two flash meaning 12 then codes will repeat ,to start flash engine codes turn key off and on three times in less then 5 sec then leave on

I have a 2005 800 Polaris sportsman.there are four circuit breakers 6 amp,15 amp and two 20 amps.
What circuits are they for?
Ok the 6 amp fuse is for the ecm the 15 amp fuse is for the cluster one of the 20 amp is main power the outher 20 amp should be for the starter and charging circuit .your over heating problem could be in the fan temp sensor you will find it on the left side of the machine on top of the thermostat housing , take and disconnect the plug on it and jumper the two wires togather with key on fan should come on if it does replace fan temp sensor .if not visibly pull each fuse out and look to see if is burnt odds of the fan being bad is very uncommon. This will be all good if is an EFI 800 hope that is helpfull

My Polaris floats when its not running. This just started. It seems to work fine. Can this be fixed?
I am guessing you mean the float is sticking and leaking gas? If so, remove the carb and have it sonic cleaned. The jet that the float opens and closes and should be inspected for wear. In some instances, the float should be weighed for fuel saturation. That may prevent proper floatation in order to fully close the fuel flow once the bowl is full allowing the fuel to continue flowing.
