Just to give you an update I haven't actually installed the lid on any stock bikes. I am down at Vforcejohns getting my cams installed and dyno'd. He dyno'd the quad with the lid and the front plugged and my jetting was spot on. John looked at the numbers and was impressed. I asked John if this lid could be used on a stock machine without jetting, The 08 EFI should be no problem the EFI will correct the mixture that may change.He showed me what the mixture settings on the 08 Brute with the lid on then with the lid cracked and the air mixture was the same. On carb'd Brutes he believes that you may have to go up 1 jet size depending what elevation you are at. He also thinks that you can run it without jetting and just be a little lean so you could go without jetting if you wish. You just wouldn't get the performance gains. I got 2HP at the rear wheel on the dyno with the lid compared to stock form.I will install the lid on some stock bikes and give an update soon.
