## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    Exactly what I needed
  

*by M***E on Reviewed in the United States on January 19, 2019*

Good quality kit. I rebuilt my 1986 polaris trail boss 250 with this kit and new crank seals,  and it's running like new. Others have stated it was the wrong size, but that isn't the case. This is the stock size. Engines that have excessive wear get over bored and need a slightly larger piston. If you don't have your bikes maintenance records, you need to measure the cylinder before ordering a new piston.

    Doesn't fit 94 Polaris 250
  

*by D***S on Reviewed in the United States on July 30, 2018*

Did not fit my 94 Trail Boss. Gap between rings too great, low compression and wouldn't run. Disappointed and will avoid the seller in the future on account of inaccurate product description.
