burning smell

[badass300ex]

I have a 03 300ex that has a full pipe, k&n and has been jetted. Dealer jetted it first without taking air box lid off. it ran fine but I wanted more so I read the dynojet kit instructions and they told me to put a 128 in. so I did. to make a long story short I took it out today and ran it hard for about 10 minutes and I started smelling something burning when i was ideling.It ran fine other than that. I didnt touch the mixture screw from stage 1 to 2 it said it stays the same. I need help Is is running to lean how do I richen it up Im fairly new to the quad seen so any help is great.

maybe it was the paint buring off the header pipe still??:confused:

I pulled my plug today and it was white as a ghost. So I guess that means lean right. Did I hurt anything in the motor when I ran it like this? It seems to run fine.

Do I need a bigger jet? or do I play with the mixture screw. Im using a 128 the biggest the kit comes with.
