I pumped fuel out of vehicle and placed it into my bike then later that day the idle rpm was at 1000 insted of 1500rpm. Then the rpm dropped and cut out. The next day it took longer to start it and then normally id twist the throttle and the rpm would raise straight away but it was very lagged and the rpm then dropped again and died out completely. Now the bike will not start at all

I should add that the fuel has been used in other cars and they work, I know this could be the difference in the jet sizes. But the cars haven't missed a beat in the slightest.
Is there a common fault with the NC30 like the fuel pump or is it more likely to blocked carbs?
Thanks Pete.
