Low end flat spot on shadow

[kendogg]

Ok so i got a vt500, though the science for carburetion is basically the same for all bikes...anyway i was hoping someone could help me...iv` got a flat spot on acceleration, below or around 2k rpm...im not sure how to go about adjusting this, i got my fuel air screws turned out to 2 on the right carb and 1 1/4 on the left. After I get past the flat spot it runs fine, they seem to be synced ok (judging from the exhaust pressure) I just cant get rid of the low end flat spot. which jet controls low end? pilot jet? anyway, thanks for any help.

I think your pilot jets maybe clogged/gummed up...being a VT500. These are the ones that most have an effect on the "off idle" to main jet. They are teenie, tiny little suckers and they are hard to see. Use a toothbrush bristle or something like it....well maybe a straight pin to get ya started for cleaning.

I'd also check the rubber boots on the carb to manifold for tightness.
