One of our customers has a 1994 Polaris Sportsman. Very nice water cooled 2 stroke that has given years of sterling service.
came in a couple of weeks ago saying it smokes & difficult to start. Did a compression test, pretty much Zero. Time goes on & they decide to go for a rebuild. Took the head & cylinder off & this is what happens when you put oil in the radiator header tank & not the oil tank..

 

"I'm sorry sir, but it appears that a glacier has gone through your cylinder head."

 

What's surprising too is the stock 94 piston with the larger port holes. This oem piston was changed to the small port holes early on.23years,that's a record I'd believe on that piston.

 

Reminds me of a Husqvarna chain saw that I foolishly lent to a neighbor. I even gave em a 2 gallon can of premix gas. They had a better idea and used their own gas.

 

One word answer for anyone who wants to borrow a chainsaw from me. Nope. I'd rather go help out myself than let someone destroy my saws.

 

Some people are just too stupid to operate a 2 stroke anything. It is a bit surprising the injector pump still works. Most just eventually fail and you simply premix your own gas as you would in any other 2 stroke engine.
