regretfully, we no longer have the proper channel to get this across to anyone who would listen. Then again, no one's there to listen. Whew

years ago, muser and I disputed this supposed myth on carburetor tuning, that one shldn't use a rich main jet to compensate overall leanness

today, when forced to recalibrate my carb settings on my bike, I discovered to my horror that we might have been wrong

zzzz

thought so. hur hur hur. this was meant for muser

reminds Adarksecret that if Mike were here, he'd smirk that you're putting too much trust in your butt dyno. Not reliable, heh.

suspects there are other factors at work such as throttle slide profile, overall carburetor venturi design, passive/active powerjets, etc.

based his conclusions on his butt dyno, plug color, and just changed his slide profile to a steeper one to lean out the lower end.

says don't forget to play with needle profile and height too.
