RedCcap 54mm Bore Piston & Ring Set with Head Gaskets Kit for 125cc Pit Dirt Bike 125cc SSR Baja Roketa Apollo Bms Nst Taotao with the Horizontal Styled Engine ATV Dirt Bike Go Kart

Fit my engine I have a boom Vader 125cc

Head gaskets do not lign up at all. Made my bike completely leak oil after a fresh rebuild. Had to drill a hole in one of them just to align the hole properly. Now I have to take the top end back off and get a new gasket that will fit.

This thing fits and functions perfectly. The value for the money is great, but the only reason for three stars is because the gasket quality just isn’t there mine blew the head gasket very quickly. Like within an hour, I recommend it other than the gaskets.

Very nice set and great price!

Apollo 125, gasket didn’t fit, o-rings and piston did

This cheap rebuild kit was exactly what I needed for my Chinese 125cc pit bike. I have been ripping it for years now and recently it has started smoking quite a bit and I coil only assume the cheap Chinese piston rings were finally wore out as they do. Now experience may vary but replace the entire top end on the horizontal pitbike engine is extremely simple. Couple bolts, take the cam gear off, and the entire top end is off in less than 10 min. The parts in this kit looked identical to the parts I replaced and fit flawlessly as I expected them to. Another 10 minute re-assembly and my bike was running like new with no smoke or anything. The value of this kit is great. Around $20 to revitalize your used up engine is really hard to beat and I’d recommend this to anyone with an older 125 that has been used and abused.

This has to be the worse gasket material I’ve ever had to use it broke apart while installing it through the bolts .

Very helpful the installation instructions are in the listing pictures.
