I’m impressed, actually…
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.

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

Thought this was good until...
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.

The size of the wrist pin size very important
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...
