[Paulfzs]

Only started today, bike bogs down and runs like crap at 7500rpm up to around 8000 then runs fine only under load, in neutral its fine


standard filter
standard plugs
does have stubby can but not been a problem so far.

23k miles on engine
regular oil changes

Around 8k is classic badger in the airbox symptoms
