I have a 2002 WR426 that I have a question on the stock breather hose. I purchased the bike last fall and have not ridden the bike in very dusty conditions until last Friday. The oil that usually comes out of it when the bike is turned off has always been clean oil. After riding in the dusty conditions, i noticed that the oil dripping out of it is very dirty. Could it be sucking dirt into the hose causing this? Is this normal? the air cleaner is clean and sealed well. Was just thinking that maybe it sucks some dust up the hose. Bike runs great and engine sounds good. Just concerned. anybody else notice this with their breather hose? thanks!
