I have a 1999 Te410 that belongs to a mate of mine. I have it to clean up and sell for him, but I can´t get the %!¤ to start. I have 30+ years riding singles, though none so modern as this. Carb seems ok, but the spark is unreliable. I have downloaded a manual, even paid for a download as well, but the official manual does not have an English translation for the ignition timing section, only German and Spanish. Can someone help me please?
