Question about 1994 Yamaha YZF 750 R
Seems that the crank/timing settings needs a closerr look than to feel that the carb is faulty.The engine is becoming rougher because the firing angle is changed. I also doubt that the carb /jet kit be replaced back with the original as the new jet is not matching.
Now start the engine and set up idle to more than minimum so that the vehicle does not stall but is somewhat smooth. Now try to advance/****** the timing and notice if the engine becomes smoother irrespective of the TDC settings. If so set to the best level and bring down the Idle , do not reduce off air but check the mixture at the exhaust to have this done all over.
Somewhere in the new change a point has been missed..
