Where do they go ? It says the increase power throughout the power band but how do they work ? Are they worth the money ? Any side effects from installing them ?

Reeds control air flow. They are between the carb boots and the jugs. You can get better performance.

Are there NO parts for the 583 motor ? I cannot find reeds for it, I search ski-doo reeds and alot of them are for the 600 engine.

SEG will find this and let you know more about it. He will know.

Your sled doesn't have reeds. Don't try to find them for a 670 either. These engines both have rotary valves. I know guys used to cut the valves, but I wouldn't recomend it.

Well that would explain it Thanks, I notice your from CNY. What club are you part of and where do you normally ride ?

I'm in the Ilion Snowdrifters. I usually ride Herkimer, Oneida and Madison counties, mostly south of the Thruway. I'll go up to Tug Hill once or twice a year too.

you can buy rotary valves that have different opening and closing values, but i don't think that it does much good without supporting mods.
