I have a siezed engine in a 07 650. I am going to have the local shop rebuild it, but first I need to remove it. Are there any tips I should know before I begain? Also I'd really like a little more power as I have already added 529 - 27" tires. What can I have the shop do to acomplish this? I have discussed a 700 kit, but I'm sure there is more. Any suggestions?
