Overheating
Posted: Sun May 28, 2017 6:52 pm
Hi everyone,
A few rides ago I serviced my bike (new plugs, oil, filters, and coolant) and initially had no problems. My second ride however my fan never cut in and I was riding round slowly with lots of other bikes so there wasn't a huge amount of cool air going through, I look down and my gauge is way over temp. I stopped and coolant was dripping all over the floor. I got it back home and topped the coolant up through the radiator cap and went out for a ride, the bike seemed fine, didn't go above half way up the gauge. Two or three trips later and it starts overheating again. I get it back and undo the reservoir cap to find the I met rubber cap seal sucking into the reservoir tank. I pulled it of and lots of air seemed to suck in. Let it cool went back out and it was fine, topped up the fluid a little more and it didn't go much above a third of the way up the gauge, so I thought ideal it's cured. However I took it out today and it didn't get to the hot part of the gauge but even with the fan on it was at the top end just under the H of the gauge. When I sped up down fast roads (60/70mph) the temp came back down to mid way or just around there until I got stuck behind traffic or slowed down in town. When I loosen the rad cap when the engine is hot, I hear gurgling and like steam/air is coming out. When I let it cool a little and take the cap completely off I can't see any fluid. Is the problem simply that there isn't enough coolant in there? Should I see coolant from the rad cap hole? The reservoir tank is full.
Thanks in advance.
