Yeah, I've read about it and they said that all the restriction is in the manifold is the size of the bore but where I buy my parts from said that even the standard manifolds are coming in de restricted now, I won't bother with that I'll just get another manifold but not sure which one as I'm keeping the carb for a while
open air filter on 50cc? wats point dude i would take that off and put box on as on 50 just makes alot noisey and wastes alot moree petrol (my personal opinion)
I do have the standard air box on, I have a open stage 6 racing air filter thinking it was going to fit and make a diffrence on acceleration but it's too much or an air flow to fit, So I'm gonna put the mini Moto air filter on and Upjet it, I like the sound of the air filter roaring anyway
