As B needles are adjustable.. they are more easily tuned than Stock needles.. but whats the difference between them as they are extremely equivalent? regardless the adjustment that is, is it possible to tune the Carbs to kick as much power as nearly to the B needles? if so what are the things i can do? so far what ive came to know about is to modify the airbox lid , changing jets and slight adjustment of the air screws...
oh yea and im caught up with a problem... wonder if anyones' ever encountered with similar problem of mine..
My engine vibrates slightly harder when it reaches between 7k rpm to 9k rpm..
and my speedo on my pgm4 will go crazy.. e.g: random speeds keeps changing... 156, 180, 133, basically jumping around.. but its working fine during revs before 7k and after 9k...
activities before this occurred ,,
had changed plugs.. NGK 9" plugs
changed my MJs to 150..
to what im expecting .. it might be my ignition cables..
thanks for reading up guys~ and really appreciate your feed backs and answers =)
