Since the air box mod I've been noticing a white (ish) tip of my plug. She runs great but I'm a tad nervous of running too lean. Will a PC help? I'm not really tech savvy so is it difficult to set up? Especially since I have really no idea which way to set it up with what I'm noticing. Thx for all advice in advance!

Im running full exhaust and a custom air filter. Mine is pretty clean on the plug but the factory computer has adjusted for the mods. You bike should be fine. If you would want you could go a step colder on the spark plug. For me the colder plug helped out a bit.

For your mods you DO NOT Need it but it will help you get a little more out of the mods you have.
but understand that spending $300 only gives you control over the top 20% of the bike.
0-80% throttle is an untouchable closed loop area

This why I wonder if the EJK is better in some aspects.... that is what I am considering getting or just getting the whole 143cc kit with the programmer and all. Hummmm...

Either way OP your bike is fine. It will adjust for the air box mod no problem.

I reset the ecu as well. Any recommendations on a cold plug?

Ngk plug. You need a 7 or a 9 I forget

Thanks, I'm not looking for someone to do the research for me but mind telling me on how to go about looking? I'm very lame in the plug knowledge dept. The factory plug was white on arch, then someone suggested this which I think he said was a racing plug and the same results.
thanks for everyone's help

I picked up this same NGK (7) plug over the weekend as mine from Factory was the Denso. (6)
I will check it out after a few km's to see its color.

The top two are standard per manual and the bottom two are high speed, what plug do you mean by 7?
