I have no real complaints about the new MP carb sync tool. If folks follow the correct procedure in the video, AND LISTED right on the tool it should work fine and give good results. The separate fluid reservoirs require the additional calibration step over merc sticks. When I borrowed the new type MP tool someone had obviously not read the bright orange warning label in plain sight on the front of the tool and had hooked it up without backing out all the individual calibration screws first - sucked out most of the blue fluid. I bought the refill kit and set it up again properly and it worked just fine.
I can recommend it. The fluid is safe to use and clean up if spilled, just rinse with water, including skin. One thing I like about it is that with the vacuum lines removed and the little rubber tube caps installed and the reservoir screws closed, the tool can be safely and easily transported.
BTW, this tool can be used to "sync the throttle bodies" on ST1300s. I think that's the name of the procedure.
Edit: I made short adapters out of some brass tube stock I had to connect the MP sync tool to the ST1100's intake vacuum tubes. It comes with threaded 5mm tube adapters w/locknuts for those bikes that use them.
