Ok so many of you may have read my post from this morning regarding my great ride yesterday. Well, I just finished changing the engine oil and the rear end gear oil. Then I went to start the bike and it was very difficult to get started. The choke wasn't working as it normally does. The more choke I gave it the engine would just die. So I had to get it started without the choke and then wait until it was warmed up. While it was running rough there was some smoke coming out of the exhaust. So anyway, once it warmed up, the idle was still a little lower then its been before, but I drove it around the block. It seemed to be running ok, but the oil pressure gauge was making this terrible friggin noise when it got to about 60psi. What the hell is that about? It never made a sound before. Now I did disconnect the cable and remove the slug that screws into the side of the engine block because as I mentioned in my post earlier this morning I saw some oil leaking from there yesterday and when I checked it this morning I could turn it by hand. So it obviously loosened itself. But it cleaned it all and then put it back together and tightened everything down and now there's a terrible noise coming out of the gauge itself. Is it possible that air got in the line? Is there a way to bleed the air out? I just can't understand why the bike would run perfectly yesterday and then be a mess this morning. I'm sure this post sounds like its all over the place, but an advice you can give would be greatlly appreciated and if you need me to explain anything just ask me what you want to know.
