For those of you who were interested in the trouble I was having with my '99 380 after putting a new piston in, here is the update.
As you recall, it wouldn't rev out very well. It acted almost as if it were running rich, but I had tried changing the jetting with very little change in the symptoms, and I was already running slightly leaner than before the new piston.
I went riding yesterday with fresh gas, and it seemed to help, but only very little. I dropped the main jet one more size, and it helped a LOT!
Apparently, there are enough changes in the way the engine runs with the different piston that jetting is affected more than I thought.
Thanks to all who responded with helpful tips. I am extremely pleased with the way it runs now.
