We always used NX Express kits in the past and there Nozzles and jetting was awesome. Never had any issues with it. Matter of fact we had our own Fill station at home and we would go thru a huge bottle of it a Season at Glamis on our Banshee.I have a boss noss system on one of my trail Mavericks, stock motor with cams and ecm reflash. I spray it with 15hp per hole and it loves it.
How do you supply a fuel feed line on a Fuel injected System to the Boss System that Siphons fuel ?
