600 twin troubles
Hello,
I'm pretty new to ATVs, but I've got an 03 600. The other day we were out riding in some mud and a little bit of water. I have had virtually no trouble with this machine that I haven't caused myself. It ran great all day and then all of the sudden I couldn't get over 30mph. If I hit the throttle hard it would sputter and choke with a little backfiring. If I slowly eased into the throttle I could maybe get to 30. Low range and reverse seem to work better than High. I checked my filter, its OK, and the reverse override doesn't seem to be causing any problems. If I move the choke **** while driving it seems to run a little better. Any suggestions?

Once you gain access to the carb (after the seat is off, take both side panels off to help), take the 4 phillips screws off the bottom... these hold the float bowl in place. After the screws come out the bowl will lower down. There will be some gas left in there so becareful when lowering it - you may spill some. Now, when looking straight up into the carb, you will see 2 small brass 'jets'. I have not taken these apart yet, but one will probalby require an 8mm socket (or wrench) to unthread and the other will probably need a flat blade. Unscrew each of these and inspect them. There may be a drop og gas left in them, so you can blow on them and get that out. There should be a perfectly clear hole going all the way thru the jet. The diamter of the hole will probably be less than that of a sewing needle. But you want to make sure bothe of these jets are open and not blocked with debris. If there is debris in there, you can try an air compressor to blow it out, use a single strand of copper wire or soak it in carb cleaner. Make sure you put the float bowl back on carefully and dont hit or bend the float arms.
