AlexT Posted July 28, 2016 Share Posted July 28, 2016 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) Link to comment Share on other sites More sharing options...
whiteknight_1949 Posted July 28, 2016 Share Posted July 28, 2016 if its getting hot could be to weak on fuel try a different plug richen the mixture also valve clearances could be to tight you seem to know what your doing so I presume you checked them when they were cold phil Link to comment Share on other sites More sharing options...

slice Posted July 28, 2016 Share Posted July 28, 2016 No you need carb cleaner, read the instructions BEFORE you use it as well. Link to comment Share on other sites More sharing options...
