ZOOM ZOOM PARTS FOR HONDA XR70 XR 70 XR70R CYLINDER PISTON RINGS GASKET CYLINDER HEAD 1997-2003

This was my first top end and for the price, I figured what the hell right?Some, ANY directions would have been nice but these days thats why we have Youtube right?Dropped these parts onto my sons XR70 and it was still smoking so I figured that I did it wrong. After replacing the carb, honest to god, the XR70 made enough torque to do little wheelies and tore the valve stem off the tube.I had to replace the rear tube after doing this top end.Hows that?

This is a great buy if you need to do a top-end rebuild on an crf70f. The only thing is, it would’ve been nice to had a diagram on which ring went where on the piston. Besides that everything went together and my son is riding again.

Perfect

Quality packaging fast delivery. I would recommend this product.

Came with faulty cam shaft which they promptly sent a new one. Runs great!!

I used this on a Honda 50 xr engine and it rips

I didn't buy this kit here however I did buy it somewhere else for my baja dr49 pit bike. The stroke and bottom end is identical to the 70cc engine so this kit includes everything you need to convert your 50cc 39mm cylinder to the 47mm bore of the 70cc engine. Everything fit great and the bike runs better than ever.
