Recent post of a fuel map by circuit
« on: April 16, 2023, 05:49:06 PM »
In the past week or so, someone posted an image to keep in mind when trying to get the tuning right.  I do not recall who, the context, the bike, or the carb(s) so I can no longer find it.  Does this ring a bell?

What bike are you working on and what are you trying to correct?

Did Honda’s Carb technical manual ever make it into the FAQ?  Describes all the circuits and how they operate, and when.

Perhaps it was in a link from a recent thread.
The post was basically the image of a page that showed polygons representing contributions by air idle screw, slide cutout, etc by throttle position(?)

I also know the post was the 1+(25)n post in the thread for some small value of n.

I have saved some carb stuff, maybe 1 of these 3 is what you are after. Or maybe 4

Thanks!  1 &  4 are very similar to what was posted and are close enough for my purposes.  Saved for later reference.

Glad it helped. I think that Twotired posted some of that info in a plug chop thread. The others came from this SOHC site, but I can't remember where.
