Why does my sled need these upgraded pistons?
The Polaris 600cc two stroke engine has long been a leader in the industry for performance and driveability. However after the small block VES carbureted models, the newer CFI’s suffer from considerably shorter top end life.
Much like the 800 CFI’s the 600 CFI piston stability is marginal. Consequently.ring lands and skirts are compromised resulting in the shortened life. Understandably, the 600’s suffer from the same QC issues the 800’s. In particular, tolerance stacking. This is when the OEM set tolerance ranges that in themselves are reasonable but when all are are at the extreme end of the range they have created a significantly weaker product.
The MCB Performance 600CFI piston addresses these issues in multiple ways.
First, we use only genuine Italian forgings that have a highly proprietary material. This allows the piston to be operated in all environments and the expansion very closely matches the castings the OEM uses.
Second, the cam profile addresses the potential for the “large end spec”. In addition the skirt profile is designed to have significantly increased bore stability.
Third, Because all these are fully CNC’d externally AND internally they are balanced to a much greater degree thereby providing a dramatically smoother & consequently faster revving engine.
Customers who have used these consistently have the same comment “It’s a completely different engine, sewing machine smooth, and feels like additional HP!”
On any two-stroke engine we cannot stress enough the importance of bore sizing and condition. Skirt clearance, bore taper and roundness on any two stroke motor, but especially on these later Polaris 600cc engines is critical. We strongly suggest replacing your cylinders if there is ANY doubt as to the dimensions or condition.
