## Customer Reviews

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    I’m impressed, actually…
  

*by J***A on Reviewed in the United States on June 13, 2022*

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.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Everything I needed.
  

*by N***. on Reviewed in the United States on October 24, 2023*

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

### ⭐ 1.0 out of 5 stars







  
  
    Blew up in less the 200 miles
  

*by A***Y on Reviewed in the United States on June 15, 2022*
