I went threw the manual on the 2001 foreman say the book say 0.03-0.04in
0.8-0.9MM
would that be .035 ?
I am using a NGK DPR7EA-9

 

0.35 splits the difference between 0.3 and 0.4, so that is a good choice. While I check the gap on my plugs, I don't think I have found one in many years that needed adjusting.

I highly recommend NGK Irridium plugs!!! http://www.ngk.com/results_appOther....=212551&mfid=1
