yeah sure.....there r two ways of cleaning them......
1) by removing the throttle and servicing is with petrol completely.......
but i dont prefer it because frequent removal of throttle body weakns the throttle disk and the screw base.... air gets leaked...
2) by cleaning it without removing.....difficult but safe......... if u want the guide with pictures i can make one do let me knw....
filhall jst remove ur air intake box and take a thin piece of cloth move ur two fingers int he TB and push the throttle disk down.....and clean frm sides.then hold the disk vertical with one finger and clean the other side.............its difficult because there is not enough space.... i do it readily after a tank of fuel..... it keeps ur pick and drive better and lighter.........
