My 2003 superhawk is making strange sounds when taking off. The engine sounds fine still but bogs and clunks through first and second gear. It was quite hot today and my fan just went do it was getting hot about 115C. Any suggestions?

 

Check your chain for stiff links, check sprockets for worn teeth

 

"My 2003 superhawk is making strange sounds when taking off." Do you lose prop rpm? lol

 

At least he didn't say "getting off"

115C is pretty warm... I've never seen mine get that high in a phoenix summer. Methinks you need to look at your cooling system, likely that there's air in it or even a thermostat that's bad (not likely if your fan is kicking on though. I'd definitely give your cooling system a flush. Maybe the clunking is your water pump even? It's not dangerously warm, but higher than I would expect in the great north...

You can easily check your water pump when you're flushing your system. It's a rubber o-ring so you don't need a gasket or anything...

Can you describe the clunk more? Does it happen at idle or just when you're doing the dirty when the light turns green?

 

Thanks aja...that sounds more like the noise now that I think of it. Appreciate everyone's input. As far as the overheating issue the fan seems to be broken because it used to always come on at 104C. And by the way 7moore7 we don't have any snow here right now and it is 36C here today lol

 

Does the fan come on at all?

 

No

 

In this case, you need to check if it's the sensor, or the fan motor
that's dead. And as 7moore said, take the time to flush, and put new
colling fluide in your ride.

 

Test your fan motor by taking the plug off of the sensor that is in the radiator that runs to the fan and touching it to the metal on the radiator or the metal of the motor. This bypasses the fan switch (which turns the fan on when the coolant reaches a certain temp) and your fan should run. If it does not, your fan motor or wiring is the culprit. If it does run, then the fault is in the coolant system or fan switch. Hope this made sense
