I'm sure if you read it correctly, he's asking about the oil content (%) not head shims, and i think that they should be shimmed to .4mm for 16% nitro anyway, unless the shimming is different on the tuned version than the Evo 2 and 3

OK, question time. I have just started running my JL modified and I have a question. Now I have read that I should be running a #6 plug (Picco taper), so I put a Sirio #6 (should be the same taper from what I have found) in this past weekend. Now what I found is that the engine temps were around 240 with what I would call more then normal smoke, and when I pulled the plug it was wet. The air temp was around 90F. When I asked a knowledgeable friend about what I saw, he suggested running a #7, which makes since to me since I have always ran a #7 in all of my other engines. So the engine temps dropped and I leaned the bottom about an hour or two. Now it ran good, but not as good as I'd hoped. Now I do understand that I am going to change out my pipe (I wish I could remember whice Novarossi it is, but it was suggested in the other thread) which will help, but my question is why is a #6 plug suggested and not a #7?
Thanks for everyone's time.........

Hey there McSquish. I ran the picco's all last year. Run the picco 2607 pipe. The #6 picco plug is fine. At 240 degrees the motor will run way rich. When I spoke with jeffrey lin...thus the JL motor...he runs his at 270+ . The motor will really wake up. I ran a richer bottom end...and leaner top.

this is true-these engines like to be a little fat on the bottom-mine runs all day long between 260 and 285 degrees and it screams-will run with anything on our track!!!!!!!

the richer bottom i think brings the temps down off throttle, and keeps the motor happy
i havent gotten next to cdub on the back stretch yet but i agree, for the money al these motors perform very well. myself and a fello racer ran evo II and evo 3 at 301s cap classic, and we had plenty motor.
