Hi guys, need some advices again I just complete a race in a very muddy condition. The muddy water cover almost up to my bottom frame, I wonder if it sucks in those muddy water. I fell and engine is dead, but I manage to fired it and finish the race. When i came back, my friend told me that they saw water squirsting out of my silencer. And they saw white smoke coming out of my of my exhaust pipe. Immendiately after the race, I change my engine oil thinking that the oil filter may choked up with muddy stuff, but it was clean! Only some fine metal chips . But I was caution that I better tear down my engine block to check the condition of piston and block. But my bike still runs quieter than my pal wr400 who he never took part in the race! Perhap I should check my plug? or open up the head cover to have a look? What do you guys advice? Thank!
