I am going to take my new YFZ riding to Mammoth riding and was wondering if anyone has any jetting specs for that altitude. It is approx. 7,000 to 9,000 feet.

Also any jetting specs for Glamis would be very helpful.

I am going to run my bike with the pea shooter out, air box lid off, outerwears on the filter and then jetted.

Thanks!!!!!!!!!!!!

for mammoth mountian, i would run a 155 main 40 pilot leave the needle and fuel screw alone
for glamis run a 160 main,42 pilot,2 1/2 turns out on the fuel screw and lower the clip on the needle one slot.
those jetting specs are for no baflle,no airbox lid.
that should put you just about dead nuts.
