Sorry jetting again!

[yzmarcimus]

Anyone out there running a KX100 with a 120 lbs rider in 90 degree temp with alot of humidity? Sons bike ran great (99 KX100) untill hot weater hit. I've been fooling with the jetting in small increments and it's still rich,(went from 55 to 50 slojet, needle all the way down, 155 main to 145). I have read some great stuff about jetting here but I was hoping for a base line for hot weather.
by the way the bike has Boysen 2 stage reeds, gnarly pipe, 94 octane at 32:1. Needles don't seem to be a common item!

Thanks,

Mark
