Piston Break-In

[phireboi]

Well I am getting a 10.8:1 compression piston and I am wondering how to break it in good, Like what kind of oil to use and when to change the oil and stuff?

you will get different responses on this subject. i am a believer of starting it and don't let it sit and idle for a period but drive it around until the temp gets up for a min or two and then go run it. higher rpms help the rings seat. you don't necessarily need to even be in 4th or 5th gear, but high rpms in 2nd or 3rd will be just fine. however, let it decelerate itself instead of you hitting the brakes or pulling in the clutch.

you will want to use regular oil, NO synthetic on break-in. i usually change my oil for the first time after about 30 minutes of riding. you may have more metal or other particles in your engine after a rebuild with new parts being installed and the engine open to the air and dust.

Practically everyone has an opinion on this subject, and very few people have the same opinion, so you'll hear everything from ride it easy to ride it like you stole it. My opinion falls somewhere between the two extremes. Anyway, here's my opinion on the subject... Break-In (http://www.geocities.com/born2bwild81/ChadsATVpage2breakin.html)

And definitely use regular oil for the break-in instead of synthetic.
