got it, now it's truth time. I was just trying to pull the plastic to do an oil change. stupi me did not realize the black plastic was not part of the red plastic. I now have the plastic off and am not so stupid anymore. lol
That's too funny! Yep, now you know. I say that a lot. LOL
Did not realize you have to remove the plastic tank cover to change the oil on a 2015 Rancher. Are you sure? LOL. My 2014 has a small "door" (lid) that you open to access the oil dipstick. I'm guessing you are also changing the air filter.
For the sake of wrapping up this thread I will explain how to remove the black selector knob. It may be helpful to someone else.
I told you it was attached with a set screw, but I was wrong. The knob is held in place by a slight notch in the metal lever. Now I remember how I did it. I removed the assembly from the bike because I had to replace the pillow ball, a spring and the black plastic "gate". So, I had it taken apart.
I placed the lever in my padded vice and then had to tilt the knob forward (rounded end) while pulling up. It was a bear for me get it off but only because I lacked the grip strength. The removal might also have involved channel lock pliers.
You have to hold the new knob angled forward and slip it down and back so that the rounded part of the knob slips over the notch on the lever.
Can the knob be removed while the assembly is still on the bike? Probably. If you're going to replace the knob, just cut the old one off! The new one goes on pretty easily.
