c3lica, knew something wrong with that bike. basically running 3 cylinders tuned pig rich to offset 1 super lean to obtain target afr after uppers take over at high rpm. cleaned/flowed inj's, retuned, u will see what u got. been thru this many times on other builds, i've had about 40 injectors cleaned/flowed since spring on all types of builds. only a very few flowed within 10% of cleaned results, worse were clogged 90%, overall probabley about a 20% average mismatch in flow rates between one or more injectors in a set. just kills hp/torque/response. bike running pretty good, i used to assume injectors were fine, i have proved that to be wrong. results on dailey street ridden bikes can be dramatic. balanced injector flow is primary to performance, highley recommend injector service. i pay $91 4 inj, $169 8 inj, the best money u can spend.
