Yesterday, when I wanted to start my Yamaha for the first time, nothing touched. The carburettor was cleaned and synchronized with ultrasound 5 months ago. Diagnosis of acquaintances and the workshop:empty jet is too because of biosprits in the carburettor. Who is to blame : First of all, because I did not empty the Vegaser properly, but I am mad at the EU and our environmental ministers+ belonging to the government, which once again introduced something that no one really wants (or needs). In the premium fuels there are E5 , so there is currently no fuel without bioethanol or other bio additives.In my car I only refuel Super 95 , but also there are at least 5% bioethanol included . Injection engines are however not quite as sensitive as older carburetor engines . What such looks like:Drainage So between 2008 and 2011 was a huge excitement in the net (also here in the forum ) because of the introduction of E10 , now you can hear nothing more . That’s why I have there Unterschri well:Petition It’s even more exciting than me…. Whether it’s useful….You have to try it, I think. If something like that violates the forum rules… then delete it!
