    Idle speed vs idle mixture screw

    Good morning! Are those pointy enough please? The tricky part will be to get the right one back inside as there is not much space. Perhaps I will try with tweezers. By the way the balancing screw to synchronize the carburators is the one between those pilot screws, correct? Is there a way how...

    Strange coughing sound and centrestand

    Hello everyone, thank you all for your replies. I changed the oil filter and poured in some new oil and finaly ( last week ) took my bike out for a ride. The weird sound is not there anymore, so the problem is solved! I noticed that the oil level was alarmingly low so I suppose the coughing...

    Master cylinder reservoir leakage

    Hello everyone, I am slowly preparing my yamaha 2A2 to get it out, but I noticed that there seems to be a leak of the break fluid just under the Master cylinder reservoir. It is happening from both sides. I checked the manual but could not find anything. Please what do you advise? Thank you!

    Strange coughing sound and centrestand

    Hello Addison and thank you very much for the reply. Pardon me for responding so late, but I was traveling. Unfortunately I don't own a garage so until I find a better solution, the bike is for the winter in my living room :). Which means that I can't run it inside, so I am waiting for some...
