We must thank Darrel for providing us with these figures during the rejetting process for his VLX600 after installing our air cleaner.

   
   
 

OK, call us parochial if you like, but when we see ShadowStuff in the submission for air cleaner, it makes our heart race a little faster. Sooo, we have decided to highlight the entry in green.

  Pilot screw turns. We had the final setting of the Pilot screw in mind here.

To do this, get the setting to the optimum for your bike and setup. When you are happy it is running as good as it can, then use a fine felt tip pen and put a dot at the 12-o'clock position on the Pilot screw.

Counting each quarter-turn, turn the Pilot screw in until it seats lightly. From this you will be able to arrive at a final setting for this current setup. Return the Pilot screw the same number of quarter-turns to get back to your setting.

Whether the bike stays that way will depend on a lot of other factors but the whole point of this web page is to offer a starting point for people to
begin setting up their carburetors.
