Air filter box bolt size
Real quick question: anyone have any idea what the size is of the threaded bolts that hold the cover of the air filter box in place? I'm looking to pop the cover off so that I can remove and re-oil my Macht Schnell air filter. Long story but my previous drill set which I used to use for this task has gone missing...and I'd rather just pick up the correct screwdriver/wrench to remove the bolts.
Thanks in advance.
