Title: The screws beneath the caps in the carbs...
Post by: jvitzu on August 27, 2009, 02:01:50 PM
What are these called on the later models? (the ones with two capped screws on each carb)

And how should they be set when rejetting a carb? Just tighten them snugly?  My bike is stock air, stock exhaust w/ 20/132.5/60 & 2 shims/needle.

Any advise is appreciated - thanks

IF they are the ones under the brass caps that you drill out and pop off

Never tight!.. They are (mixture screws) and mostly are at about 2.5 turns out w/ factory parts.. you have to set them based on your aftermarket exhaust/filte/jet combo

OK, noted.  When I took out the caps, these screws were tightened down, so I was a little confused about why all the FAQs talk about "3 turns should be good".  I thought maybe they mean the Idle air screws in the float bowls, but that clarifies - thanks.

You may have touched them inadvertently with the drill...running them in as a result?  :dunno_black:
