Okay this ones an odd ball, and before I start I'd like to say thank you to all of you who have commented and helped me out on my previous posts. I apologize if I don't respond... it's usually because the problem got fixed... anyway, my buddy and I just came up on a free coolster 70cc pit bike for his son. It runs good, shifts good, very happy with it especially for that price haha. What I'm still trying to understand is the weird air filter assembly... hopefully someone can shed light on this. Why the hell does the air filter have a hose coming out of it that leads directly back into the motor!?????!??!??
What is that for? Cause I was just planning on removing it, operator the bike with just a straight carb to air filter like 100% of the other pit bikes but I can imagine there is some reason it's there?
