You should definately search and look at the sticky at the top of the forum under "increasing your IQ" for many good threads but here goes for me. I have worked with mine to get it to this point and it RIPS, I couldn't be happier with this set up.
Gear to 19/42 or 19/43 (I have 42) Run Ron's weights for your altitude
(username "Ron" here on snowest, contact him give him your specs, he builds a true custom weight that is key to my performance I believe, thanks Ron),
Carls Cycle helix, from memory its 64/42 .40 ER or close, easiest to just buy from Carls on line. (talk to Ron first he may have one) I run SLP blue/pink primary, basically a 140/340 spring. Make sure your primary is clean and make sure you set your belt side clearance right. Most stock seem to be off with 115 belt which is what you should run and dealers don't set them up right from what I've seen(or don't bother in most cases). Set the side clearance to 0.015" or near. This makes a big difference, underated performance gain on this sled.
Run stock black/purple sec. spring but add Delrin washers. I run two, one under the cup, one between cup and spring. Available from dealer or TEAM.
Make sure you set belt deflection right. Another underated and often out of adjustment performance gainer. Run it tight, to the point of squeel or creep but a hair less.
I run single pipe and PCV SLP stage 1 map, ethanol wires connected but I run higher elevation, 3000-9000. Map still seems a hair rich but they do say to turn on a low elevation "accel pump" option on the PCV for low elevation riding so not sure for you on the PC111, look into that.
AKSnowrider on here I think is a low elevation rider with a dialed in similar set-up, you'll see his post in many threads.
Good luck and enjoy.
