I have an 03 (carb obviously )zr900.I bought it used last year,and finally tore into the carbs this yr.Are the jetting charts right out to lunch on these or what?
It has 430 mains in it right now.I am at about 1000' above sea level,and will ride down to about -25degrees celcius (~10 below farenheit) also all the crap they call gas around here has 10% ethanol.So by the jetting chart I should be running 470 or 480 mains?does that sound right? seems like quite a jump :cold:
No mods other than a helix.I may be adding a tempa flow as well.I have one sitting here....
thanks for the help guys...
