I think the Theory of "boost bottles" was the charge would have somewhere to go when the reeds are closed and not loose inertia, Was a big craze in the 80's but they diisappeared from bikes as quiclky as they appeared so you would guess they probably did next f**K all!

The strange thing with the Nsr is on the 28 they disappeared from the inlet manifold between the carbs and reeds and appeared behind the carb on the airbox intakes???? Very strange and know doubt still achieved F all!
