I just finished my air intake modification to my 2007 H1 as was wondering if I need to rejet. I stayed with the 1 1/2" size and cut the stock hose of right outside the airbox and put a 1 1/2" elbow on it. It doesn't sputter but I here they are really lean from the factory already. I just don't want to ruin my engine from running it too lean. I' ve attached a couple of pictures to show what I've done. Any advice would be helpful. Thanks.
