Had a hell of a time adjusting my valves today for the 2nd time ever on my '06 EN500 LTD. I followed this tutorial:
...and everything went fine with the valve adjustment except for two big PITAs:
1. My valve cover would NOT come off. One of the two metal tubes at the end of the coolant hoses was stuck in there, preventing the cover from coming off. I highly recommend leaving the hoses attached and using those to tug on--don't do what I did, which is detach them. Took almost an hour to remove it, prying carefully with a flat-end.
2. What's with those goofy rubber "nuts" used to attach the starter coils? I always have a hell of a time unbolting/re-bolting to them, but again, the cover won't come out without removing them. You can't grip the rubber bits, and they spin with the MF bolt. I ended up getting one off and leaving the other one on.
Anyway, on to my real problem. The instructions say to drain the coolant, I suppose so that you can move the reserve tank out of the way(?). After dealing with the dreaded coolant hose screws (changed them to allen-heads) -- I had just flushed the coolant, and went to replace the drain screw, and the HEAD BROKE OFF inside the hole. You can imagine the colorful language my neighbors must have heard.
To make matters worse, it is not tight enough in there to stop a very slow coolant leak. I have never tapped and removed a decapitated screw like this before, especially in an engine. Can someone walk me through it? Or am I "screwed" and have to go to a mechanic?
For now, I have to move the bike, i.e. run it, so I'm keeping a bowl underneath to catch the dripping coolant until I can get it somewhere to stay a while.
