Long ass story with this 04 gsxr 600. Replaced the engine replaced the harness replaced the throttle bodies and stva. Still had c28 code, stva and butterflies and sent ecu to get flashed for the extra air being added and also used a 2004 gsxr 100 fuel pump. The three test rides I did there was only one time/pull where I can use all of the tachometer. The bike just won’t go past 9k rpms and the end of the video I’m full throttle redlining it and it just bangs at 9k. I’m so lost I don’t know wtf to do I had this project since October it’s been a lot of bullshit all across the board I just wanna fix it and get rid of it asap.
