I have a 1999 Arctic Cat Triple Touring. Just had it in the shop and had the carbs cleaned and a new fuel filter installed. Problem is that after around 5 miles, I lose power. Sled will still idle, but when giving gas, the engine bogs. Engine will still start when doing the bogging mode. If I let it sit for a half hour, the sled runs like a top for a while and then repeats the bogging. Checked plugs and they look to be OK, no crap on them. Also when in bogging mode, if you give it gas long enough, the engine backfires. Could it be the brain box, the coils or something else? It is a water cooled engine, but I don't think that its over heating. If it was over heating, you would have a difficult time starting it and keep it running. Like I said, it idles good. PLEASE HELP!!!!!!
