OK new dilema, my sos racing in mammoth and we just made the switch for Kawi's to the Honda's
Last year in both his 85 and supermini, we did non jetting change at all and ran straight VP MXR02 and they ran awesome.
Any ideas or suggestions etc?

I would say a jd jetting kit will get you as close as possible without being there. JD has done the research so its plug and play for the most part.

Maybe someone who rides at same elevation/conditions can pipe in.

Racing Mammoth Looks like a blast. I would like to race there someday.
