Thanks guys, I had already checked ebay, so I posted another thread here to see if someone has one for sale. I like that watch crystal idea... I don't care if it doesn't look that good, just want to ride the bike. I do have a master cylinder from my EX500, they are the same except that the one on my Vulcan has the thread for the mirror and the EX500 MC doesn't have that. I can use that one in the meantime until I get a Vulcan MC or maybe get different mirrors that attach differently(?). I'm not sure, gonna scout my options... I did want new mirrors, so if I can find some that don't mount on that particular hole, it'd be great.
I was kinda disappointed today, was looking forward to testing the bike and see how it performed with the carb cleaning, adjusting the screws 2.5 turns out, the marble thing and all... but I couldn't even start the damn thing... desperately needs new spark plugs but I can't find them locally... I only found the regular ones (not iridium, not even platinum... copper?) and they're almost as expensive as the Iridium plugs are in the U.S., so I'm definitely not buying them here.
I really hope I can get the bike back on the road soon :-/
