Reply To: Strange running problem – GV125 C Fuel Starvation [Solved]
Go to halfords and get “WYNNS FORMULA GOLD” (dont touch redex whatsoever) , pour the entire bottle inside the tank.
Make sure to drain the OLD fuel first as it has probably gone stale and the carbs inside may have old deposits clogging the jets
Use E5 fuel only and the entire bottle of that Formula Gold , ride as much as you can until you get about 2 bars of fuel drop down, this should allow the Formula Gold to “Soft Clean” the entire fuel system and probably move any debris or old stale fuel varnish inside the jets, we expect the bike to respond better.
Let us know if that improves bit by bit ? then it was the fueling system.
It would be a good time to look at your spark plugs.
If unsure, upload pictures of your spark plugs so we can see the threads and the center cone, we shall know how the fueling is by reading the plugs after a long run (at lower speeds so you don’t stall if the carb still needs cleaning out/ cobwebs blown out!)
