i agree you should just do and learn ....i hate to give my needle settings because the will deinitely not work for some people ....if you tune your motor based on common sense and facts ...the motor will tell you what it wants ......its hard to try and not help someone with there motor .....i want eveyones grp to run as good as mine has for many gallons ....unfortunately they wont because all peoples conditions are different ....i believe if all else fails go back to stock settings ....and tune from there ...if that fails and the motor doesnt hold a tune ..then you have a problem elsewhere ...and well you know how it ends up from there
