Hey, Fred, thanks for your quick response. You're saying that I will cut off the long bolt to get the relay arm off, then that would give me a little more access to the centerstand bolt/nut? If I can't get the centerstand nut off, do you think I can still go at the bolt head with the sawzall without damaging the side of the centerstand?
No, thats not what I meant.
You need to remove the right side centerstand bracket so you can get the long bolt that goes through the relay arm out. The bracket has two bolts that hold it on the bike, but only one of those bolts cant be removed when the exhaust is on (the lower one, as I recall). You will need to remove both of the nuts on that side, or at least loosen the one youll be cutting the head off of. If you rounded off the nuts youll have to use vice grips to get them loose.
On the left side of the bike you dont need to remove the centerstand bracket at all, just take the pivot bolt out so you can get the center stand out of the way, but leave the bracket bolted to the bike on that side.
The long bolt through the relay arm will come out once you get the spacer loose on the right side. It tends to get stuck in the hole that it runs through. After you remove the nut on that long bolt, you can pull it out as far as it will go to the right (head hits the exhaust pipe) and that will give you just enough room to pull the relay arm down and out. Youll probably have to pry it out because the stuck spacer is wedging it in there.
Once the relay arm is out you can put the nut back on and use the bolt itself to pull the spacer through the tab. The head of the long bolt is small enough to go right through that frame tab. Make sure you shoot that spacer with a lot of penetrating oil before you try to extract it.
Alternately, you can just leave the spacer stuck in the frame tab and jam the relay arm back in there after you get the bearings lubed up. I usually like to pull the spacer out, clean and grease it before reassembly.
PS - That video goes into removing the swingarm and greasing the swingarm pivot. I dont recommend bothering to do that. The relay arm hangs down under the bike and gets hit by all kinds of road spooge. The swingarm pivot is pretty well out of the weather. Heard of lots of relay arm bearings going bad, but never once heard of a swing arm pivot going bad, even after a few hundred thousand miles of rainy riding.
