my ypvs cam with keihin 28mm cabs on + pod filters my pipes are small end allspeeds where the power band feels from 5 to 9k range am i better off changing back to standard carbs and airbox or just standard airbox and leave these carbs on. the bike runs fine with them on there, its premix which i will be changing and the pods are louder then the pipes    the cracked hoses are on the list  |

Allspeeds will tail off at 9k
The pwk's benefit is midrange and throttle response
Personally I'd rejet to 38/135 and fit the airbox

That's standard kr1 jetting which isn't a million miles off a ypvs with airbox and pump and pipes
I'm tuned/stroked and on 35/140 with drilled airbox, pump and TSA's

Can you be sure that those carbs are not copies?
Non standard overflow pipes, different fixings and no QC marks?
Have they got a Sudco or Sudcoo sticker on them?
