Jetting, 21st-Century Style


So this is how you jet a fuel-injected bike in the 21st century.  No jets, no needles, no "spray bottle cap to catch the fuel from the float bowls..." -- you hook a USB port up to a power commander, connect the PCIII to a 9-volt battery, install the CD, and away you go...









A fellow RC51 rider with the same exhaust system and similar injection mods (pair and flapper valve) suggested using 1 of 3 possible maps to start, with his "best" stock map as a starting point.  And hey presto, the information was downloaded to the PCIII.  It just needs to be installed on the bike!









A suitably-equipped Dyno shop would have a PC hooked into the Dyno, a exhaust gas sniffer, and the PCIII itself.  Based on the fuel-air ratio of the bike set up, the dyno operator could go in and change the values of each of these quadrants to fine-tune the performance of the bike.  Cool!  The new PC5 is such that (from what I understand), the unit can store 3 maps, and you can toggle between them depending on your needs -- mileage, performance, or even dodgy conditions.  MotoGP for everyman!

Still no shock, so I'm not going to bother with the exhaust yet -- get it tucked away before I snug down the headers.
