Valve adjustments are pretty easy on the boxer and brake fluid changes as well. Plenty of YouTube vids to scope out the work. Zero impact on resale IMO.

Are you going to hurt the value by performing the service yourself - No!

Flushing/bleeding the brakes is as straight forwards as 98% of every other bike out there. You do not need any specialty tool. Old fluid out. New fluid in. Bleed & done. I use a section of 5/16 ID poly hose an old soda bottle and the right size wrench for the bleed nipple.

Valves on the Hexheads and Camheads can and do stay in spec for a long time in most instances. However the only way to tell where they are is to check them. Your's may or may not be within the specified range. It's not so much a mileage thing more so a individual bike thing. On a 2016 you will also want to look for cam wear.

The rubber stamp thing. Personally if I were concerned about service records I would want the dealers service paperwork to backup the rubber stamp. I don't care about an ink blot in a book. I will say if I did find out that a private seller was stamping their book to make it look like a authorized dealer service was completed it would bring into question their integrity. In the day and age of computers it's not hard to call the dealer and get a copy of service records.

 

Thanks for the advice, guys!

 

Here's my Hi-tech brake bleeding system 😬 works on cars just as well as bikes.

 

No need to pay BMW if you can do the work yourself which many riders do, just hold on to your receipts and you won't hurt resale value at all.

 

Take pictures with your phone as you go...just takes a second and has a date stamp as well.

 

As most here, I do my own maintenance, unless it's something I do not feel comfortable with...think MAJOR repair. Brakes, fluid changes and even drive shaft maintenance I'm doing.

 

None of the bikes I have bought used over the years came with any service records. I just do a full service reasonably soon after getting it. Sooner if something obviously needs work right away or if the brake fluid looks like French Roast.

 

In the newbie column, how do you service a later model bike when they’ve stopped producing shop manuals? I have a 2023 GSA. Thanks for any guidance towards a good resource.

 

What services are you looking to perform yourself? While there may not be a shop manual readily available they are avaliable or at least were last year to download for a few dollars on the big auction site. If you cannot find a downloadable version there is a ton of information in the internet with several video tutorials for things like valve adjustments. Biggest problem there will be sourcing all the tools needed. The cam timing jigs, TDC tool and shims are available the cam timing chain tensioner is whats is hard if not impossible to source.
