Hello, I wanted to ask if it is really necessary that you have to pull all valves in the 2nd customer service. I drive a Honda cb125f and the workshop where I bought the moped wants in my opinion too much money for a customer service. I have to make my customer service with a Honda dealer, because otherwise I lose the warranty. So I also asked different dealers and there are quite different prices like 400€ without accessories so tires and ke or another 250€. Where I still find that this is too much or? Now to the question, it is necessary to pull the valves after, or the moped continues without errors even without pulling them. Of course, I would then have to give up my guarantee, but that would run out anyway in September this year. So you’d rather have valves pulled or you can save yourself that. Thank you in advance.
