Hey guys so I'm having troubles with my 03 R6 stunt bike and its really getting on my nerves any help would be greatly appreciated! so basically it all started on the weekend I was at the lot practicing first time i been out in over a year due to a injury my bike sat for that whole year i never fired it once i had it stored with full tank of gas. so i was at the lot and bike was running great was practicing endos and then i decided to crank the idle up for some idle wheelies and my idle screw popped out of the bracket and it went downhill from there. it started sputtering and dieing even died in mid endo. idle was speratic and engine almost sounded like a vtwin but when i pinch the idle screw it runs fine makes no sense.
So when i got home i checked it out it would run just like shit almost like it was running on 3 cylinders didn't even sound like a R6 unless i pinched the screw then it sounded fine through all the revs.. so put my gas tank up to check throttle body and tps tinkered around and tryed starting it with the tank standing straight up (can the fuel pump suck in air into the efi?) cause now she wont even run just turns over. So then i looked around the forums and there is a diagnostics you can do right on the gauge cluster(i don't use it) so i grabbed that and hooked it up and its blinking a 13 and 15 which i guess are error codes. 13 is Intake air pressure sensor - open or short circuit detected. and Fault code No.15 Symptom
Throttle position sensor - open or short circuit detected.
so first thing i did was take my tps off and clean it with electronic spray and made sure that the groves moved freely re installed it then i ran the diagnostics in the gauge and n01 is tps throttle closed throttle open these are supposed to be 17-100 i think mine read 0.. I'm so stumped on this my fuel pump sprays fuel like crazy tested the battery its charged if i pour gas down the carbs it will fire for a second. its almost like something is telling the fuel injection not to turn on or its plugged or sucked up air from trying to be started while on a incline if i look into the carb and turn over i see no gas going in. idk im stumped any help would be great sry for the long msg but more info is better right! thanks Cody
