So I got the T6's for my '02 shee a while back. I drilled holes in the airbox lid, apparantly in a place that didn't help at all, and 'jetted' it. It still ran like crap. I've been trying to jet it for a very long time now (almost sold it twice from frustration), and just now thought "Hey, what would it run like if I just took the lid off?"
So I did. Wow.
Before, I was getting beat by my friend on his YFZ by about 1 1/2 bikes up a 100 yard hill. He got cocky, pissed me off, and I got even more frustrated. So I called him after my little air box lid deletion for another trip to the dunes. So, all cocky like, he rode a wheely over to the line, as I putted over, then proceeded to smoke him 6 times in a row.
In front of his girlfriend.
I'm adding on some V Force 3's, hopefully they'll give me a little more kick, too.
