NEVER let the motor labor in a high gear,NEVER let it idle to warm up..drive it,NEVER hold at set speeds/cruse for long periods..it take a new piston 60 hrs to 'heat cycle',rings not as long,about 30 hrs and bearings 1/2 the time of rings..DONT mess with mixture,RICHER is BETTER on a 'green' motor...Change the oil after first 1000miles...synth Vs dino is BS..ALL the CDW27 Protos ran with synth 'out the crate'....
