I have just about put 500K on my Tomos Bullet and was planning to change my gearbox fluid and at the same time switch from the Crappy Tire ('Motomaster') 2-stroke that I used to break it in to Yamalub semi-synthetic in my injector.
I would like a little advice on how to do this technically. Stupidly, I filled the injector with the Motomaster stuff so now I have to get rid of that before filling it with Yamalub. So, 2 questions:
1. Anyone have a better way to get out all of this oil than siphoning? Should I just diconnect the hose and let it drip out?
2. Do I need to 'rinse' the injector out with the new oil or can I just add the Yamalube to the small amount of dino residue that will remain?
