Having just bought this bike 10 days ago second hand I am having overheating problems. Low on cash and a student, I'm hoping to replace things myself... Maybe some of you gurus can offer some advice on what could be the cause? (please) Here are the symptoms:
First of all, the bike is fine when moving but in traffic it overheats and last night it actually shut down the engine (I guess there's a fail safe). Obvioulsy i wouldn't have kept going if I knew it was that hot as according to the temperature guage at the time it was in the middle and no where near the red zone. So I guess my temp guage is faulty?
Next: I read on-line that if you can see coolant leaking from the pump the seals are probably gone. Well there is some leakage but do I really need to replace the whole pump or just the seals?
It has lost no fluid (apart from minor spots out of the water pump), so I don't think there are any leaks elsewhere that could be causing the overheating.
Should I go for a new thermostat, radiator flush and pump seals and see if that works? Would that make the temperature guage operate correctly? Cause I guess the radiator cooling fans aren't going to switch on until it gets to at least half way on my faulty temperature guage right, which could be adding to the problem.
One other crazy thing happened: The engine shut down (turned off) as mentioned last night when it presumably overheated and I left the ignition on with the radiator cooling fans doing their thing. I put the bike on its stand and suddenly after about 4 minutes the engine re-started automotically. Unfortunately my bike was in gear though and it went flying off with no rider at the helm. My immaculate body work is now scratched and the gear shifter snapped off. Gutted! Has anyone ever heard of a bike automatically starting again - seems pretty crazy! True story though.
