I have my neightbors tennage boy's honda 400ex atv. He brought the thing 2 months ago with it smoking real bad(blue smoke) using oil. I told him 3 weeks ago to buy a top end kit with the new cylinder, but he brought just standard rings & piston. Torn it down yesterday and told him we are wasting our time here. Because the piston that came out looks new and rings, but there is almost 1/8" movment in piston in the cylinder without rings. I check the end gaps on the new and old rings in the cylinder and they all have about 1/4" ring gap. So I have told him to buy a new standard cylinder $165. or just buy a standard top end kit with cylinder for $180.. Or take cylinder to machine shop and let them check it and tell you what size piston to get. But looking at buying piston/rings is over $120. So you my well just buy the whole kit. Then there is resleeving it, wish I found standard sleeve for $80. But I have never remove or installed a sleeve. Are they hard to do with basic tools. Because that would be the cheapest wat to go. Because the kid as no $. So i'm just looking for cheapest way.
