I have a stock lt-80 with a lightened clutch and an K&N airfilter. I am currently running stock jetting (92 main and 17.5 pilot).
I just purchased a FMF fatty pipe and the turbine core 2 silencer for the woods. I also purchased reeds as well. What should I be changing my jetting to? Also, I usually ride at sea level, however, I will be making a trip to the high desert here in Oregon within the next couple of weeks. The average altitude is around 4500 to 6000 feet. I/we will be doing most of our riding in the 4500 range. Should I be adjusting for this altitude and if so, to what?

Thanks...
