Improper bearing tolerances is another common issue 900-1000cc engines 

Many of these engines will throw a rod or spin a bearing without any notice whatsoever. 

A journal that is too tight will preload the bearing, which will increase internal friction and temperature and lead to premature bearing failure. 

Here at Rev6, we do not take any chances. 

Typically Polaris will have codes on the engine cases and crankshaft that will directly correlate with a color bearing that polaris recommends using. 

Sometimes those tolerances will be too tight or loose, causing premature bearing failure. 

Rev6 addresses these bearing issues with plastigage to find the correct bearing tolerances to ensure there are no premature failures on your new engine.  

Specially on aftermarket engines running Carrillo rods that require a plastigage for optimal fitment. 

Why do we only use nikasil Coating on all of our cylinders?  Nikasil-silicon-carbide is one of the most effective and toughest setups you can offer. 

Nikasil cylinders offer tighter piston to cylinder wall tolerances for better performance, better heat dissipation, and are stronger than your standard cast iron bore.

What's the common issue with the RZR/Ranger 900-1000 engines? 

We typically see these engines failing because of excessive play in the steel valve guides that Polaris offers. This causes the user to notice oil loss, or run out of oil without them knowing. 

These Pro star motors will often show no sign of burning oil until it is too late. 

If you notice a loss of oil and no external leaks, I would recommend getting your engine checked out. 

We address these issues by using our upgraded valve guides. 

Why do we use bronze valve guides? 

The C63000 Bronze, nickel guides provide superior resistance to wear, out standing heat conductivity, maintaining critical thickness in high temperature areas. Bronze valve guides promote high performance and endurance on race engines and your standard builds for more reliability and longevity. 

One of the most common issues we find with these machines is a dusted engine. 

Engines with improper or faulty air intake systems can ingest dust. Dust will act like sandpaper and wear all internal components. This will cause power loss, excessive oil consumption, among other things.
