Jetting seem right?

[Wbdisco]

After pulling my SC and putting the Keihin back on I decided I would check jetting on the carb. I never checked it since I bought the bike and it is running great as far as I am concerned. Does this combo seem right? I have checked the database and cannot really find anyone running the same. I ride between 600-2500? elevation.

I had to get the old magnifying glass out to read the needle, but I?m pretty sure that?s what it said. Like I said, it runs good, minimal spooge if any. If anything it would be nice to have a little more snap on the bottom.

Jetting Database Thread

Go to the jetting data base thread and start at page 11. Everyone has their jetting specs listed there. It has anything and everything right there. Its a wonderful resource.

I?ve browsed through the database and the jetting 101. I couldn?t find anyone with the 164 main or a listing of the needle I have. I?m still learning the jetting stuff. It runs good so I don?t want to mess with a good thing, just curious on the numbers.

Just curious - where are your idle mixture screw and your idle screw adjustment set? How many turns out for each one?

I will double check when I get home. If memory serves me though, I believe the AS is around 1.5. Idle is perfect at 1250rpms all day. I?ll chime back in later when I get off work.

Plot thickens boys. Had some spare time to really take a look at this carb and settings. I?ll post this on the database thread as well just to document.

Anyone? Seem overly lean? I have no clue on how to interpret the needles.
