Hi all.
I had an interesting overheating problem with my K100RS and was wondering if anyone has had a similar experience.
I was coming back from Tamworth to the Sunshine Coast Queensland a few weeks back and although it was pissing down with rain the K was purring like the proverbial kitten and I was clearing cagers with ease. Then I came to Cunninghams Gap, a pass over the Great Dividing Range between the Darling Downs and the Fassifern Valley in Queensland Australia for those not of these parts and being the end of a long weekend and school holidays the cars were as thick as flies on a dogs back, only much slower. Nothing for it but to tuck in and crawl along behind. After about five minutes I glanced down and my temperature gauge was well into the red. I pulled over as soon as possible and checked the coolant, which was fine then started up and kept going. The K had cooled down a little but soon crept back into the red. Thought that once I got some speed up it may help but there was no difference. I slowly made my way to the nearest service station and pulled in for a closer look. I thought that I may have had something blocking the radiator core but it was clear the bike didn't seem overly hot. Cut a long story short I had no choice but to keep going and hope I made it home.
Next weekend I pulled the radiator out. Emptied around four litres of coolant out first which was about right. Core was in very good nick, thermostat worked well, flushed the core and it had good flow. The electric fan was stuck, very hard to turn so I pulled it apart and freed it up. Much cursing later it was all back together and ready for a test ride. Everything back to normal, only time it heated up was when I stopped. I let it heat up to the point where the electric fan cut in and it cooled down nicely. I have given it a good work out since then and never looked like overheating.
Anyway just thought I'd see if there are any theories out there.
Cheers
Bryan.
