That's correct. The blade uses a close loop lambda and hence requires the O2 eliminator to provide full control of the fueling via PCV. It does mean mpg will suffer as a result but also means no more snatchy throttle at small throttle openings ...
Hi guys, ive been reading through this thread, and think I must of been lucky when I fitted my r77 on my 2008 blade, as it runs nice and smooth at all revs and speed with no other mods done to my bike. Just one of those things I guess.
