I really need to know who the manufacturer of carburettor is and size/model.
The KR-1/S came with Keihin PWK28's, fitted with 38 pilot and 137 main jets.

I'm assuming the carb is a mikuni like the dtr125 etc. if it is then a 190 doesn't sound too big to me, the tzr250 2ma has 230 main jets in each of its 28mm carbs.
