I have backfire in the carburator
Dear forum members,
I hope you can help me here.
2 months ago I bought a Yamaha Raptor 350cc from 2008. Everything went well until recently.
If I drive slowly in low revs then I get backfires in my carburetor and at that moment he also holds back. If I go through everything goes fine it's only during slow driving I have the worst in 2nd gear around 30km / h.
I then did these things myself:
Carburettor cleaned in an ultrasonic bath
New spark plug
But unfortunately nothing helped, so I brought him to "De Liége Quads". They have cleaned the carburetor again and cleaned a new spark plug and air filter. At first the problem seemed a little better, but it soon became apparent that it is still the same.
Does anyone here have an idea what it could be? I am slowly starting to turn gray.
thanks in advance
