I use a set similar to the Emgo gauges Here's a link on EBay -- http://www.ebay.com/itm/UNIVERSAL-MOTORCYCLE-4-CYLINDER-CARBURETOR-SYNCHRONIZER-TUNER-5MM-6MM-/302156960566?hash=item4659f55336:g:bRoAAOSwo4pYRDVy&vxp=mtr
I've found these to be a bit more accurate than the Carb Tune type and very easy to use
This link even comes with a carry case. What I have is more like the following kit I have, though mine didn't come with the tire spoons. http://cgi.ebay.com/ebaymotors/Vacuum-Carburetor-Synchronizer-carb-sync-Gauge-3-Spoon-Motorcycle-Tire-Levers-/391655319777?hash=item5b3079e8e1:g:tbQAAOSwZJBX~Uke
