If you are needing a tune up and not wanting to do it yourself just have the shop do it. It isn't ridiculously hard but isn't something I want to bodge. If you are confident and want to do it and have the proper tools to do it as @
Rolla listed go for it but I would probably rather just send it to the shop and get the bike back faster and go riding on it. It sounds like a sweet set up. Post pictures when finished (and don't forget drive side is the important side.)
