I ride 2 smokers, I purchase long lengths of over flow tubing, I route said tubing and aim it to my expansion pipe. If I smell sweet smoke, then she's a overheating! One thing to remember, pull off your cover to your water pump. If its gummed up with alloy corrosion, and all the passages are clogged, it not flowing. Its a good idea to flush your coolant system and verify that your pump area isn't corroded. After flushing it, fill it with a good ethylene glycol mix and you should be good to go. Verify that your radiators aren't clogged with mung, and always clean your scoot after riding, lubricate all cables, controls, and chain after washing. Good luck!
