HELP! I bought a 2001 XR100R (CRF100F) for my son and after reading a bunch it looked like a 112 main jet was the way to go after removing the baffle and replacing it with a power tip/spark arrestor. Various Honda web sites only list a 98 as the max main jet but that is what it has stock.

What is the part number for the jet I need and what needle position should I run? We ride between 200' adn 2500' max.

I also am changing to a Moose high-flow air filter but how can I open up the air box more?

you can drill a 1 inch hole in the top of the airbox under the seat but that will change what your jet size should be
