[I ride a lot 123]

I was Riding With my buddies who also ride 600 when I noticed there bikes where running faster then mine where I was confused then when we came at a light a kid told us too rev our bikes each one by one all of there bikes where able too red line but mine it’s accelerated quick to 8 - 9k rpms and then kinda made a bogging noise likee it was going up and down I recently just did the fuel pump with a Fpf fuel pump, new coils, new air box filter, oil and oil filter, new chain, my bike is running a full exhaust no cats idk if that could be the reason my bike is not redlining and performing bad I don’t have a tune I haven’t checked my injectors yet but I am in the morning rectifier and stator working correctly so it’s not that I tested it bike accelerators great but just won’t redline and gets stuck at 6 - 7 k on first gear and 8- 9k rpms on 2 - 5 gear and 6th just climbs but won’t go over 100 mph it’s like if I’m in a limp mode or something I would really appreciate if y’all could really help me and try and find the problem this is very frustrating

welp, go over your work first off, make sure nothing is pinched or installed incorrectly..

then test, fuel pressure, flow, does your bike have an active cat or flapper valve? was that disconnected properly as in delete kit installed? any codes? coils tested and 100%, was mapping ever messed with as in ECU flashed?

if your buds have the same bike maybe one of them would let you install their ECU fora minute to see if it changes anything?

Why did you do a fuel pump? You need to do a fuel flow test and properly diagnose the problems. The test is in the factory service manual.
