Hey guys hoping someone can help me out. I normally run my idle around 3k, but when I'm up in 12 for around 5 seconds or so my idle will drop to about 1k and ill see the FI light flicker really quick. To "fix" it ill clutch it and rev it up a bit then the idle returns to where i had set it. The bike normally will run good until the bike heats up to full running temp.

Tested my tipover (bike runs while on laid down.)
Checked connections everything seems snug.

thanks guys

My f4i would start runnin shity everynow n then after riding for a while n I couldn't tell what it was. Eventually it just stayed runin bad for a lil bit so I checked the temp at the begining of each header to see which cylinder was the problem. All read 400 except #2 wich read 150. So that narrowed it down. I swaped coils around n still #2 was colder. Pulled plug n it looked fine, pulled injector n blew w comp air. Still #2 cold and running shitty. I got a new injector and now my bike runs great all the time. Just thought this might help ya narrow it down some.
