------------------------- Conall et al, A little clarification would be helpful for me. Having JUST replaced my front sprocket for the first time, I'm not sure what you mean when you say the countershaft would slip while trying to turn the sprocket. My sprocket has a spline that mates the to countershaft, and a metal "retainer" washer which is also splined, then the 27 mm nut. I don't see how the countershaft could slip inside the sprocket, unless the spline were stripped which seems almos impossible (not to mention disastrous).

thanx robert for you reply , heres all the info i have from the test. @rpm 2800-hc 30 , co 1.2 @ 3800-hc 14, co .53 @4800-hc 10, co .40 @5800-hc 3, co .50 @6800-hc 5, co .90 i did the test to give me an idea where to start on the carb. so far i figure to un screw pilot maybe 1/4 turn put in slightly larger main and change needle to one with clip so i can hold it out and probably use a stepped taper as it seems my lowest readings are in the range where those variables factor in. as for needle size i don't know the archives suggest i'm maybe a little big but why the low readings? maybe floats low?thanks again for your time
