petrol usage on derbi gp1 50 revolution
kneight said 2007-02-27 11:47
Hello, I have bought a wonderfull looking and well performing gp1 50 revolution completely standard. I took out some junk from the exaust and it went 80 kmh on the counter. But dispite of it´s speed and well handling it has a high petrol usage! I´ve orderd new cogwheels in size 16 instead of 19 standart size and brought it together with a fine polini racing vario.. Now it goes from 0-70kmh in about 4 seconds.. not bad for a standart scooter with a adjustment price of 120,-. Still i´m not satisfied with the petrol usage...:P I hope somebody knows what I can do about it.. many thanks
