I have been running a 145 main jet, not a 140. [img]i/expressions/face-icon-small-blush.gif[/img]

The 145 is sufficient if you do the pea-shooter exhaust cut out, remove the baffle from your snorkel and upgrade your air-filter.

It is NOT sufficient if you, along with the previously listed mods, open up your air box & do the internal muffler mod (use a 1 3/8" hole-saw to cut out that tube that is behind the spark arrestor) . You'll run lean and it is significantly noticeable (aka that front end won't come up when you gun it). A 152.5 (so far) is adequate, my Z wants to throw me off of it like a raging bull again.

Please note I'm in detroit, so if you're at a different elevation alter the jet size appropriately.

Sorry about the misinformation, especially to anyone who put a 140 in. *sigh* [img]i/expressions/face-icon-small-sad.gif[/img]
