September 29, 200817 yr hi there i have recently bought a rev 4 and was wondering what sprocket sizes other owners where using mine is 10/42 and i think it is a tad high geared in 1st . also can any one tell me what the c and a on the electric fuel tap means and how does it work . any help would be very appreciated thanks zarkoff.
September 30, 200817 yr 10/42 has been lowered. Standard is 11/42. I have ran 10/42 all year and had no problems. When the fuel tap is pointing down. The will only go into the carb when the engine is running. When it is pointing up fuel continously flows. So always leave it pointing down unless you have emptied the carb, by draining it or tipping the bike upside down. I hope this helps.
September 30, 200817 yr I use 10/41 as I found 10/42 a bit slow but it really depends on the individual. I've never heard of anybody going lower than 10/42 though.
September 30, 200817 yr Author thanks for the info. i will stick with the 10 /42 it maybe that i am used to my other bikes which just seem a bit slower in 1st thanks again.
