Alright. I removed them. Both. The performance gain was HUGE!! I put a crank case filter (K&N style) on the oil reservoir and the other hose I ran to the back that came from the crank case.
I asked neighbor to come out as I had previously raced him before on his son's 2006 Scrambler 330. He won by about 2 quad lengths last time. So, we lined up and wife walked out laughing. Two old guys about to run them...lol. Beat him. Wow. I was impressed. I beat him by 2 quad lengths now.
The only think I can think of is, I am tricking the EFI into thinking the Ranger is cold? Since only cold air comes in now and the tubes aren't hooked into the air box anymore it thinks the Ranger needs to run richer and gives it more fuel to warm it up?
So, called dad up. Parents live about 2 miles from us. Told him. He is bringing his '07 Ranger XP down. Last time we raced he beat me by about 6". All of us are equal riders too! I'll post back tomorrow.
