I forgot about this thread in the midst of my clutch issues, and waiting for Suzuki to quit screwing up. The warehouse sent the dealer 2.50 shims in 2.55 packaging. So I had to wait another week to get my intake shims in. They're here, finally. Looks like I'll be popping the new shims in tomorrow morning and syncing the carbs. Then I get to ride it and see how she runs. I hope the sync gets rid of that surging.

Update: The shims are in and the carbs are synced. It felt really good seeing the neighborhood, so I'm going to take it to school today and see how it goes.

Update 2: Woohoo! She runs like new! Thank you everyone for your help. She still has an afterfire, but I'm going to just say it's the exhaust. Everything else is in perfect shape.
