Top 20 things not to do to your BMW motorcycle

by Duane Ausherman

This is a collection of ideas and tips offered up on Boxerworks.  I am only posting them and claim no credit, but I must admit that I agree totally.  I have edited them for clarity and completeness.  In some cases I have added a link to more information about this issue.  This list in not in any order of importance, it is just a list.  Note, this list is often in the top 10 pages visited, so somebody is reading it.

1.  Do not over tighten the axle nut.  Do not use the axle nut to pull the axle through.

2.  Do not turn your forks while the key is inserted into the fork lock.  Do not leave your key in the steering lock whilst maneuvering your bike in the garage! You may break off the key and it is better to have to do this procedure. 

3.  Do not tighten the center valve cover nut.  Just beyond finger tight is enough.  You will regret tightening it to what seems proper.

4.  Do not step on the “tang” to use your center stand.

5.  /5 and later.  Do not over tighten the nut on the end of the camshaft where the ignition advance unit goes.  The end snaps off easily and you will need to buy a tool from “Paul Tavenier” repairhead@sbcglobal.net

6.  Do not forget to clean and grease your center stand pivot bolts annually.  Replace the bolts periodically.  They can deteriorate and may break.

7.  Do not forget to remove your tank and flush it annually.  Change your fuel hoses periodically.  These two steps (Every two years or 30000 ks???) may help prevent the leaking carb syndrome.

8.  Take your clutch arm pivot pin out on back tranny cover and replace it with a bolt and nylock nut before your pin falls halfway out and breaks off your cast aluminum bosses on back of the /6 transmission cover.  That sucks.

9.  Do not forget to take the negative battery cable off when removing the front cover. Check for grease.  Scroll down to near the bottom to see greasing the terminals.

10.  Do not fill the engine sump with oil before you re-install the drain plug.

11.  Don’t let the points wire get pinched when you replace the front cover, or the ignition won’t work.

12.  Always keep air pressure in tires at close to proper psi.  Within a few psi at most.

13.  Don’t start your bike with the Allen wrench still in the alternator bolt from the valve adjustment.

14.  Don’t check your compression with the throttle locked open with the cruise control, and then get busy cleaning your bike, doing other things for a while, and then start the engine.  Very dumb.

15.  Do not pull out without first raising your kickstand.

16.  Do not over tighten bolts.  See #3 above.

17.  Do Not…  Ride away without checking that you’ve tightened the axle pinch bolts…  or caliper mounting bolts…

18.  Do not forget to check all fasteners after doing any work.  Take if for a test ride.

19.  Do Not ever say “I’ll just do this little 5 minute job before I go for a ride”…  The 5 minute job is guaranteed to take 5 hours.

20.  Just a joke about not contradicting me.

Some suggestions, in addition to the top 20

The dental floss master cylinder overhaul tip, its for getting the rubber seal over the end of the m/c piston.  Make 2 loops of floss [a floss/seal/floss daisy chain] and use the floss to stretch the seal out/over the piston then cut the floss and remove.  Makes a difficult job very simple and quick.

Over tightening sump bolts etc.

Don’t mix up the long and short drive shaft bolts.

Block the /5 and later crank so it can’t move forward for rear seal replacement.

Don’t leave the ignition on without starting.

Don’t think you have to make your bike look showroom new.  Let it age.

Play nicely with others, even if it means waving to the Harley riders.

Don’t use a 1 ft.  long wrench with an added 2 ft.  breaker bar to tighten the 4 driveshaft bolts to the transmission output shaft.

Do not mix up the rear caliper mounting bolts

Do not stop without putting your foot down.

Do not spit while moving (esp.  with wife riding pillion).
