The purpose of this research was to investigate:(1) Influence the use of water injection to exhaust gas emissions level of CO and HC on Honda Supra Fit2006 motorcycle. (2) Influence of variations the diameter of injector on the water injection to exhaust gas emissions level of CO and HC on Honda Supra Fit2006 motorcycle. Based on experimental result can be concluded: (1) The using of water injection gave the effect to exhaust gas emissions level of CO and HC on Honda Supra Fit2006 motorcycle. There is a positive effect on CO emissions because the use of Wa-I 21G has CO levels decreased by 1.901% and the use of Wa-I 23G has CO levels decreased by 1,920%. Whereas for HC emissions there are negative effect on the use of Wa-I 21G has HC levels increased by 1236 ppm and the use of Wa-I 23G has HC levels increased by 1140 ppm. (2). The diameter of hypodermic needle as water injector gave the effect to exhaust gas emissions. There is a difference of exhaust gas emissions level of CO and HC when using Wa-I system with the 21G and 23G injector type. Based on the results of measurements, the use of Wa-I 21G produce levels of CO 0.019% higher than Wa-I 23G, whereas on HC emissions the use of Wa-I 21G produce levels of HC 96 ppm higher than Wa-I 23G.
