NICECNC 70CC Big Bore Cylinder Head Rebuild Kit Compatible with ETON Viper 50 Lightning 50 Impulse50,Replacement for most Chinese Scooters with JOG/MinarelliI/Yamaha CLONE Motors

Well, I obviously thought this thing was garbage since it was only 60 bucks… boy was I wrong! After a little port cleaning and air-fin shaving, it popped right in with minimal effort. After cranking with the ignition off for a while (we don’t talk about that), thing started with a 1/4 second of starter engagement. Man, the difference! That tired old Axl-50 was given new life, and it even accelerates up hills now! Overall, I’m impressed with this kit, it includes everything you need and is not bad in the quality department after a little cleaning. I recommend for minarelli 2t clones.

Fit perfectly on a Eton Beamer 2 Model PN2. Recommend porting/sanding rough sharp edges on ports and piston.

When I first put it on and broken in with would just shut off like it blew up I let it sit for 5 minutes then it starts back up started doing it more and more then it wouldn’t start had like 15lb of compression sent it back and got refunded

It lost compression after 20 days of use

Customer service took a long time to deal with but they made it right. Several emails back and forth but only until I made my review did they respond. The pictures show what happened to my cylinder and it was installed right.. I did install another and so far it has not blown up. Again they did stand behind their product and made it right just took a long long time.

I have too clean transfer ports but she's pretty clean, nice stock head, all around decent for your 💰, ggz

Worked great , just clean up ports before install and check ring end clearance

The wrist pin was the wrong size, so this whole product will be returned. A new one will be ordered from a source that explains the importance of the wrist pin size and give the specs...
