I had to bring my 04 636 back to the dealer today. It looked like the bike might be leaking oil out of the clutch actuater (SP) and I had a tooth broken on my front sproket. Now normaly I would be upset that the bike has had a couple problems but it doesn't bother me because when I call the dealer they say "It's under warrenty, just bring it in and we'll fix it". Some ppl will say that fixing it is their job, and your right. But I have had somethings happen with the bike the ppl in the shop could be like "Broken tooth on the front sproket!!! What are you doing wheelies or taken the bike to the drag strip and beating on it" but they don't so that's cool. Just thought I'd share that
