YPVS Loses Position(?)

Toomey pipes and Toomey jetting. Really ran fine until about May.

I am not familiar with Toomey, but do they have internal baffle(s)?

Wirges for Kaw H1's were notorious for breaking baffles and flopping around at different positions at certain RPM's.

This is why I ask.

What changes, mods, or maintenance was done in the time immediately preceding this?

Ok, scratch that.

Thanx!

Going back to the first post in May, one needle was replaced and the tank was sealed.  Did either of you check the needle dimensions and compare those to stock or the the needle that wasn't changed (or the one that was)?

[2steve]

I did measure them to compare with higher quality calipers.
They were really close to each other at the tip, midway and near the top, plus overall length.

That still doesn't explain why I'm running the highway or interstate in the good rpm range and it slowly winds down to a crawl or completely stops

If it does come to a stop, it will kick back to life like nothing happened. This behavior started the bowls-running-dry theory that has been disproven and appears electrical in nature.
