A.S. -1 1/2 turns out 48 power jet 7.0 slide I run this jetting from sea level to 4000' do to trail riding Running 50/50 race/pump fuel @32:1 MX2T.I only get a little spooge,but the plug is a light tan color with the carbon ring at the base of the insulator.I have gone far as a 158 main jet but ran into heating problems..Hope this helps..
