My son races 4-5 stock class in the Michigan mxrracing circuit and I am trying to make his sled competitive. At the end of the year I bought a few things and I'm trying to fine tune it. I got the quick hub for the gears and the adjustable main jet. I put everything on and it ran great. But the circuit requires a air box. So my question is what happens to velocity stack when air box is on? The sled runs night and day different with stack on and box off. It's very sluggish with just the box on. Any help would be great I'm news to the 120s and racing in general. Any other tips to make it go fast in his class would be very helpful to. I'm open to any ideas, he seems to really enjoy it and I want him to be competitive and not be in the back cuz dad doesn't know what he's doing. Thank you Craig Brevik8@msn.com
