Installed a pc5 and QS on a 2003 cbr600rr and now the bike bogs out a bit in the lower RPMs. It's not stalling out or dying, it's just kinda stumbles a very little bit. I haven't been able to take the bike out yet. It's been on the stands so I haven't really revved the bike. At the same time I removed the pair valve and did the plugs like 300 miles ago if that. No kinks thst I can see in the line while body work is off. Only mods are graves block offs, micron slip on, BMC filter, pc5, expansion module, and QS. Any input is appreciated.
I'm sorry that was a poor choice of words. No 100% it's not perfect. It's back to where it was when I just installed the PCV though originally. It's going to to be tuned by the end of the month.
