Hey all, I was looking at my pipe on the Kodiak and noticed that there were a few pen size holes . Should I go and buy a another stock header? Or invest in a aftermarket pipe? Will I need to rejet? Hows the bikes engine going to do long term? I only use this bike 5 times a year and for plowing in the winter. It only has 1200 kms on it :):) and works great. But off topic my son drowned it in a huge mud hole I have never seen a machine make it though. I cleaned the air filter and changed the oil and oil filter several times until it was clean; I think it was 12 litres of oil. Oh and I drained all the water out of engine. Is there anything else I should do? It works great now.

I would stay with a stock pipe..otherwise you will have to rejet with a aftermarket pipe. I would check ebay for a good used pipe.
