premix 20:1 ?????

ran almost 30 hours on a plug

only 30 hours? i run whole seasons on a set of plugs.. jet em right and your fine.. i guess if your someone that consistanty screws with jetting 30 hours is a long time.. but for anything less than a race bike get the jetting pretty close and call it good.. no reason to run a trail or play bike on the ragged edge...
 
30:1 with KLOTZ supertechniplate 2.

Only oil i will run for now on,my honda hp2 sh*t sucked weiner,stunk,didnt burn too clean and was just terrible over all.

my jetting was dead nuts on, carb tuned dead perfect, half choke -40 degrees out ice cold motor and she would fire first kick, never had any bogs or hesitation, no ping nothing, i changed plugs every 30 hours just because.

never ever fould a plug out,
 
40:1 is about as lean as ya wanna go. 32:1 kinda fouls plugs for me with my big carb. I use some where between 2oz of Interceptor and Dominator and mix it with 93. That's a fire breather for ya.
