My son has outgrown his 2008 CRF70F so I think I may buy a 2007 CRF80F for him. I have looked through the jetting sections but did not see anything pertaining to a CRF80F.
We almost always ride at Hungry Valley (Gorman, CA) that is located at about 3,500 feet altitude.
Thus, does anyone know:
1. What jetting should I run?
2. Should I use a different needle (what Honda part number) ... and if so on what clip height?
3. With new jetting and needle, how many turns out should the fuel screw be set?
4. For 2007, the fuel screw is a D-style anti-tamper type. Is there a direct fit adjustable fuel screw to use (what Honda part number)?
5. Any other simple mods for the CRF80F to improve power or handling?
