I just I picked up a 2002 XR650L with 6k miles on it for $3000 and it's already been modified quite a bit... White Bros E-series exhaust (sounds awesome, by the way) smog removed, K&N air filter, etc. I ran into one BIG problem, though... I think the bike is actually DRINKING WATER! I rode the bike with no probs whatsoever in dry weather, but a few minutes after riding in heavy rain, the bike started acting like it had water in the fuel. The airbox was muddy & wet... It totally looks like the bike has been sucking water up through the drain tube and water is making its way into the combustion chamber! Is this a known problem? If not, I think I just discovered it... Does anyone know how to fix this? I feel like snipping the drain tube short like the tiny one on my "R" and hiding it in dry space against the front of the rear fender. Should I do this? I believe that running a K&N filter creates enough of a vacuum inside the airbox to be sucking all this water from underneath the bike when I ride in the Oregon rain. Somebody please let me know if I am making sense. And, tell me what to do... snip the tube and put the pinched tip back on? Thank you in advance for any help! Ride red!!!
