ZX750F1 Need Help From Italy
Hello I have a ZX750f1 since 1987. I had the installation of a drain 4-2-1 with duct slightly enlarged airbox . The motion , however , does not run well and if you look at the image that I put more down will do an idea.
the valve clearance is ok , candles are new , the coils work perfectly.
the jets of the maximum have been replaced , and are passed by the measure 112 ( original ) to the extent 122 to the outer carburetors ( thus the number 1 and number 4 ) while for the inner cylinders ( then number 2 and number 3 ) I opted for one size 126 jet.
