Nope, twinmax won't detect that. Nor any other vac gauge.

0=0 still valid. Nothing wrong there.

No again, I'm afraid. Doesn't take much to throw these off.
Dee's bike is a case in point.

Glad you got it sorted Dee. It's easy to do more damage than good while rooting around. (Did it to myself on the SV a while back - needed a dyno to figure out where the problem was) I saved myself some cash by getting the top end jetted just right, but botched the low/middle in the process. Had to ante up for some dyno time anyway. In retrospect, I could/should have found it myself, but it doesn't always work out that way. Happens to all of us.

Good riding.
