burning oil

[lenman20]

03 rx 1 5k on motor burning oil a lot of oil. when its cold it spits oil out the tail pipe. what is the remidy for this. do i need a new motor or is the motor not breathing enough. i cant beleave the ring could be gone allready. need lots of help with this one

Came to the conclusion that the problem is to do with the breather system.My warrior burns about a quart in 150 miles.Tried sea-form,no difference.Looked in the air-box to see it soaked with oil.This oil is then sucked into the engine where its blown out the tale pipes.I don,t believe that the rings are bad because it runs REALLY STRONG(112 on GPS).Hope the motor does not go south on me,had a arctic cat 94 puma do that to me on the day i got my 98 indy 500 .(cat ran really strong on that day,before the crank let go).Still can ride here in southern newfoundland,just waiting on parts to fix my destroyed secondary.Now i know how cat owners feel all winter.

there is oil in my breather. how do i fix this breather problem

Do a leak down test on the engine. The course of the issue goes like this;

A little bit of oil goes through the breather into the intake, where it gets sucked in and burned. This causes some carbon buildup on the rings and reduces ring seal, causing increased blow-by and crankcase pressure, which accelerates the oil going out the breather. Once it gets beyond a certain severity, it snowballs and no amount of snake oil will correct it.

The issue can be managed by REGULAR use of snake oil BEFORE the problem snowballs out of control, and by ONLY using 87 pump gas. High octane fuel doesn't burn as completely and causes carbon buildup.

I suspect that your engine will need new rings. Use 05 or newer rings since they are less susceptible to carbon.

the problem is the 03 rings, period. they wear out and loose the seal causing blowbye. carbon has nothing to do with this. as for performance mine radared at 116mph with crapped out rings. when the engine was torn down there was no carbon in the rings or ringlands.

When i changed the oil(after using YAMAHA combustion chamber cleaner) at the start of the season the sled ran 200 miles before it started using oil.Seems like the oil breaks down,oil comsumption goes up.
