Gentlemen, I think am one of those who post more to ask questions than answer.
After ages of experiments with the BS 29 carb and jets, I had finally settled on a BS 32 carb, 17.5 pilot and 120 main. Goldstar mimic exhaust. No PAV and D-0100 K&N in the stock side box.
Well this set up ran great until about a month back when i did some changes to the breather. Erratic running, loss of acceleration, in short - PITA to ride.
Since I reverted some of the breather changes, thanks to the guys here, the bike runs much much better.
However, there is this strange expulsion of air(?) underneath the carb flange that attaches the carb onto the intake manifold.
While in idle, there is this sudden,intermittent noise(just like those buses do, on releasing air) and the bike tends to stall. Same issue when riding as well.
If i place my fingers on the underside of the manifold rubber, i can feel some agitation and the set up really vibrates(although its firmly connected).
No crack in the flange rubber or the rubber connecting the airfilter and the air box. Fuel supply is good.
I am baffled. Please suggest..
