Hey guys, so my injectors aren't firing on my yamaha r1 09. Everything else is working fine, but the only time the bike will turn over is if fuel is put into the air box. There isn't any engine mods of any sort. Anyone else have a similar issue? a thread i've read is saying that the battery is an issue, but if it's been starting up fine off air box, then shouldn't it be fine to fire the injectors too? I've run the battery in there now off other batterys and it's turned over fine. help!
