two K1300S bikes, S1000R & Vespa 150 Primavera clown paint job
Most of you have found that the brake fluid and clutch hydraulic oil reservoirs have child proof caps. Here is the tool that slips in under the cap and pushes those little tabs back so the cap can screw off. Find the tabs slip in the tool over them on each side, leave it in place and unscrew the cap. Best 6$ I have spent on the bike. It is about 2mm thick.
