the bog on acceleration in my car was a lean one. so shutting off any bypass cured it. But I think a 0.35mm bypass hole would get rid of the black smoke shooting out the sidepipes when hitting the gas.But black smoke is still preferably to a bog. A larger bypass would definitely make things worse.
In Priobes case I see to large an air corrector there, so you need a large main jet to make up for that. Maybe going down with the air corr. you could take a smaller main jet too . In my case when revving up under load with the 210 air the mixture would lean out. Not a good thing. With a 115 air I got that sorted out and could go with a smaller main for a stable mixture ratio up to 6500rpm.
