Posted July 28, 20168 yr Hi my name is Alex , live in London and have 2 bikes (Yamaha vity 125 2010 , Honda PCX 2012) With the Yamaha I have some problems when the engine is warm. First i had problems even when i was waiting at the stoplights , it would turnoff, after i adjusted the valve clearance it doesnt turnoff anymore but when i drive it and it gets warm , i cant restart it if i switch the engine off, need to wait for it to cool off and it works. Changed the sparkplug,the valve clearance is okay ,battery okay , airfilter okay, can this problem relate to the carb ? Or what seems to be the problem ? Kind regards! AleX P.S. Got this bike from a guy that didnt drove it too much and i think it was kept in a garage for some time ( had spider webs on some parts)
