The Honda CB500T manual is wrong in this case - slow and pilot jets range from 35 to 40, 38 being the most commonly seen.Alfalfa said:well i took it apart again and the slow jet (#38 but manual says should be #80) looks like it is clogged half way down. I tried running some wire through it to clear it up but that stuff is stuck in there good. So then I filed a nail down to fit inside the jet and still the damn thing won't go through. Also it looks like there is some kind of brass plug where there should be a hole in the pilot jet here is a pick. Should I just buy a new slow jet and pilot jet?
Main jet anywhere from 140 to 150.
There is no jet in the carb that's 80 size.
What is identified as a "pilot" jet actually is a plug, there is no hole in it, at least from the top (or end that hangs down in the float bowl, with the number stamped on it) - that's why you can't seem to clear it out. The pencil points to it in the photo.
The photos are actually of a 450 carb, but they're the same as 500T, except for the goofy "air cut valve".
The "slow" jet lies underneath this, screwed in the little tube or cavity (arrow #1).
It receives its fuel from a tiny passage that is connected to the main jet cavity (arrow #2).
It's a bit difficult to see from the photo, but if you pull it apart you can see the little passageway.
Arrow #3 points to a little brass sealing ball, pressed into the opening that was used to drill out the little passageway.
Does this help???
