Reply To: Bike won’t start – GT125 Comet
Go halfords and buy the yellow “bradex” easy-start , spray the air filter for 10 seconds, put it back on the airbox or spray inside the airbox – Make sure the airbox is on and secured (harder to start without it properly)
Full choke, crank and let it scream to life , then see if the carbs will run on choke for 5mins, then slowly turn the choke off
If it dies, let us know – Also check if both cylinders are hot if its running on choke?
you either have fueling issues from a clogged tap, clogged pump , (yes new parts can get clogged up if the tank has debris) or the carbs need attention (likely “Starter Jet” that is permanent is clogged, pilot jets clogged up) or even the carb passages (every hole in the carb) is clogged
Or you will need to check your intake manifolds, and replace their O-RINGS if there is micro leaks under there causing a loss vacuum to open the pump / carb isn’t being utilized properly by the engine due to vacuum loss)
Check spark plugs if they are wet ? (fuel is entering engine, therefore it should spark and start)
