While having a look over the bike at work today, i noticed coolant had been leaking out of the rad onto the engine and down the side of the bike. So i took the rest of the day off to go back home and diagnose the problem. The radiator has had a previous repair from a prang i had a while ago, and the coolant looked to be coming from around that area. So straight on the phone and strongly request an immediate re-repair to be done to get me back on the road. When i arrive at the rad repairers and show the fella the problem, he asked me if i did 'a lot' of wheelies. Which i thought was a strange question to be asking. Then he showed me some other damage to the same area, where the fins had torn away from the rad's frame. Classic wheelie damage he called it. I know i looked pretty embarrassed, but i must have looked conflicted as well, because he took one look at me and said, "I don't think i can reinforce it to stop it happening again". And i said "i don't think i can stop doing wheelies to stop it happening again". So he's going to look into it for me. Fingers crossed. Anyway, the rad's had two hits and a few hundred wheelies put into it, so I'm not surprised it's showing signs of falling apart. But the bloke also said he has seen the same thing happen a lot in his time of fixing rad's. So this is really a heads up to the other wheelie junkies out there. And maybe on the off chance someone knows how to reinforce a rad to stop it from happening. Scheff.
