I thought the 550 would require the least amount of attention because its air cooled ? What updates should I be looking for or doing?

Watch the 550 like a hawk. They like to burn up. Make sure all the updates have been done for the oil and cooling.

The 550s have the rep from the cowlings being so tight around the motor. Also polaris did not increase the cooling capacity when they increase the motor from 488cc to 550 cc.
They have a shroud for the cooling fan to get cooler air in. Protects it from sucking air from the exhaust pipe.
A oil return line was put in because they think the oil was boiling.
Also believe they was a updated cdi ignition to retard timing a little.
Check here for good polaris info
