Hi we are going up to Mammoth this week and are wondering if anyone has run a YZ 450 up there with a similar configuration, we usually ride at I-5 MX and LACR I run a 42 pilot needle one leaner than the middle and a 162 main.
I will be running the VP U4 Oxygenated fuel up there.
I have installed a 160 main jet and lowered the needle again, any thoughts?
