Why is the piston on my Polaris engine not working?
FINDINGS: We find that the OEM Polaris Piston will NOT hold its form after a very short time of running. We have found it common to see the piston to cylinder wall clearance DOUBLE in less than 1000 miles.. THIS is the #1 reason behind these cylinder failures associated with the Polaris Engine!!
What causes cylinder to double in Polaris engine?
We have found it common to see the piston to cylinder wall clearance DOUBLE in less than 1000 miles.. THIS is the #1 reason behind these cylinder failures associated with the Polaris Engine!! IT IS NOT due to a rod ratio error! It is SOLELY related to excessive piston to cylinder wall clearance!
When did Polaris start making their own Pistons?
We have been designing our own pistons since 2005. This piston WILL address the issues associated with the OEM Piston! The piston is custom designed with different ring location and oil feed holes and pin location. These are the BEST pistons you can buy!!
What are the gaskets on a Polaris piston?
NOTE: ALL pistons come with Rings, Wrist Pin, and Circlips! NOTE: RKT Top end gasket kit is comprised of the Base Gasket, Y -Pipe Gasket, Exhaust Valve Gaskets (Non-HO ONLY), and Inner Compression O-rings. These gaskets are not part of the piston ONLY kit but are available in the options.

When did Polaris drop in piston kits come out?
Our “Drop In” Kits have been in existence since 2001. They are PROVEN Kits that WILL deliver the performance claimed. NO HEAD REQUIRED! NO HEAD REQUIRED!
What causes a Polaris snowmobile engine to fail?
The MTNTK fix kit addresses piston failure that is common with some Polaris engines. The failure is caused by the piston clearance in the cylinder being ill-fitting and loose, allowing the pistons to rock in the cylinder bore.
What causes a piston to crack on a MX bike?
In most cases the top of the cylinder and the occurs. Most mx bikes have head stays mounting the head to the frame. Over time the head can become mount. It’s important to check for warpage of the head every time you rebuild the top end. cylinder clearance was too great. When the piston is cracks and eventually shatters.

What happens when the big end of a piston cracks?
When the piston is cracks and eventually shatters. washers of the big end was too great. When the big end vibration. This leads to connecting rod breakage and catastrophic engine damage. The big end clearance should be checked every time you rebuild the top end.
What happens when a piston breaks on a MCB?
When the piston is cracks and eventually shatters. washers of the big end was too great. When the big end vibration. This leads to connecting rod breakage and catastrophic engine damage. The big end clearance should be checked every time you rebuild the top end. To feeler gauge between the rod and a thrust washer. Check manual.
What causes a piston to seize on a piston?
The main causes for this (main jet), or too hot of a spark plug range. vertical seizure marks around the circumference. This the piston. As soon as the engine started and the piston against the cylinder walls and seized. The optimum cylinders vary greatly. For example a 50cc composite need between .0055 to .0075 inches. For the best manual.
