I got mine installed this morning and I am extremely happy with it . I installed the accelerator pump software and set the sensitivity to 90% , the fuel % increase to 20 and for 20 RPM . This really makes throttle response sweet. After 5 test rides I ended up with setting the low RPM range settings to + 6% or the third bar up from 0 , the mid 3rd bar up also and the high to 2nd bar up or 4% increase over the map that comes installed . My mods are modified air cleaners (very little restriction ) , the maniac mod and drilled out exhaust with SET valve open .DHandyman said:I noticed that DynoJet uses a silver 109R for their stock image... hmm.. think they actually have a preference for fastest bike?
