the rubber tube on the left side of the frame in front of the engine, after i shut my bike off after riding and go in the house for about a half hour, i come back and there is white stuff on the ground or on my stand coming from this tube. my dad said it was crankcase condensation. another of my friends said he never seen anything like that on a fourstroke before. can any of you tell me what it is and if i should worry about it and if its normal please? if it aint normal, what is it and what do i gotta do to fix it?
