Re: quick question about 2-stroke quads
All quads, not just 2 strokes have to warm up before they run their best. The piston and rings grow slightly as they heat up, making for a better fit inside the cylinder, which raises compression. The reason it doesn't lag after you shut it off to take a break while riding, is everything takes much longer to cool off again than it does to warm up for the first time in the morning, so it's still warm and ready to go.Also since the piston and rings are always a little bit sloppy in the cylinder when the engine hasn't warmed up yet, don't try running it hard until you know it's up to normal operating temperature, otherwise you're increasing wear on the engine. Just keep it mellow for about 5 minutes of riding before reving it out hard when you start out for the day, and the piston and rings should last much longer.
