Oh... interesting discussion... now I wonder if I'm doing this correctly.
What I do is take the top plug out after using the bike.
After a ride I get a little dribble out, not too much. I understood this was a good way to check if I have the injection rate set correctly. I.e. I should get a bit out, and that shows I have enough being injected, but not too much as that would show I am over injecting.....
I also leave the plug out when I store the bike. Because I don't have an oil shut off valve and the injector passes and if there is a lot of oil in the tank it can drain into the crank case over time when the bike is stored over winter for example. And if I didn't drain this down to the upper plug the engine would be over filled with oil when I run it....
So knowledgeable and experienced guys.... do I have this right?
