Quick tuning question
« on: Jun 18, 2011, 18:40:51 »


Hi There!
I just finished rebuilding my 1979 XS650 Special and put on straight pipes and pod filters, BS38 carbs and I just wanted to know the tuning protocol. Start it up and let it idle then check the plugs. If it is rich or lean what do I adjust? The pilot jet or Mixture screw. I don't have a tach so how do I adjust the screw? Also for the main jet etc. Thanks a bunch!

Best bet is get on http://xs650temp.proboards.com/index.cgi?
They have carb guides which will give specific advice.
