WHOA! Dump that dealer fast! Premium gas only (highest octane possible) - never 87 octane. No valve adjustment at first service. Whoever you talked to is either an idiot or a snake or both

I'm coming up on needing the first service done on my 636. I stopped by my dealer yesterday to see what all they are going to do. The labor alone is $165 and then the cost of oil, filter, etc. They said it will need to have the valve clearence checked which is the bulk of the labor. Is this necessary? Also, The only thing I've noticed is that at idle the rpm varies from 1200-1500 rpm. It will idle at 1200 and then go up to 1500 and then back down to 1200. When I asked the service guy about it he asked me what gas I was putting in it. I've been using Amoco 93. He told me to only put 87 in it. Should I listen to him? I have read some guys use 87 but the majority of things I've read(including my owners manual) is to use at least 91. This is my first bike and I need a little advice here. I don't want to screw up the bike! Thanks!
