ECCPP CYLINDER & PISTON KIT ASSEMBLY For Honda Z50 Z50R XR50 CRF50 50CC DIRT BIKE PIT BIKE

Works great! Thank you

well made and quick delivery.

Nice kit for a rebuild. Gasket set was packaged under the cylinder damaged two of the gaskets. Need to ship on side with cardboard on both sides.

About what'd you'd expect for $35. Bought this a few years ago, finally getting around to installing it. Everything still sealed in original packaging. Went to install rings on pistons, 2 different colored rings, both have FR marked ok them. Neither fit in the upper 2 grooves. I could probably force them in, but that's not how piston rings supposed to work. Guess I have myself a $35 paperweight. I would try another cheap Chineseum kit before I waste my money on this one.

My Honda crf50 was low on compression. Roughly 30psi. It would barely run. I saw this kit and thought the price was too good to be true… and it was. Sort of. I installed this kit without issue. All bolt holes lined up just fine. Wrist pin was much thicker (more material in it) than the original adding weight to the piston. This is ok as this is not a performance bike. After install I was reading 80psi cold on compression. Honda spec says it should be 140-170. I figured after the rings got seated and it was warm the numbers would be significantly improved. I heat cycled the motor by idling it at roughly 1000 rpm for 10-15 minutes and then letting it cool completely. On the fourth start up I warmed the motor for another 10 minutes and then pulled the plug for a compression test. 72psi. What a bummer. It was worse after break in. It was an improvement overall to the bike but not what it should have been. For a kids bike it’s fine. We will see how long it lasts.

Did exactly what it was supposed to do. Went on smooth and bike runs like a top.

Had to reuse the old oil o-rings, so hopefully it holds. Did 5 break in cycles, and drove it after that. All seems ok, so far

My daughters four wheeler and this thing worked like a charm.
