Our airbox drains route into a catch can which has a radiator style drain cock . I have opened this drain a couple of times , didn't see more than a drop come out . Assumed the drain must be plugged . On the trip to Ohio this past weekend I saw elevated engine temps , especially on the return leg causing me to limit speed to 45 at times on level road . Needle was at 210 a lot , sometimes going above 210/215 but never to 230 . I will post more about this in appropriate place .
Back to the airbox , I was concerned about the high temps hurting the engine so was looking for coolant in the wrong places . Oil dipstick shows no sign or smell of coolant ( I know it should be analyzed) , exhaust looks good . Rad full . Unscrewed the drain cock completely from the airbox drain catch can , nothing came out . Removed hose at check valve , nothing . Removed check valve , it rattles , works as it should . Nothing came out of pipe from air box .
From what I have read , Detroit two stroke " slobber tubes " are known to drool fuel/oil . Just wondering what others have experienced before I pursue this further .
Thanks ,
Chris
