It started by having an intermittent lean spot while cruising on the trail. The next day I was kicking a ski-dont's a$$ and it fell on it's face and started missing badly, very embarassing 
. I found a fouled cr10 plug and immediately changed my plugs to cr9's. Took a ride and found that it was lean , 16-18 afr at 10% and up on the tps. I also noticed that I had fuel in my oil tank. I run a walbro 255 lph with modified injectors and the stock regulator. I assume the regulator is the problem and it is causing my fuel pressure to go up and is dumping a ton of fuel in the cylinder not allowing it to burn and then making my afr read lean. Probably why I fouled a plug too. Also I checked the check valve on the return into the tank and I was able to blow though it with my mouth, no jokes please. Has anyone had problems with their stock regulator?? I have a 2:1 and I plan on removing the stock one, but I need to make a block off plate with a barbed nipple on it so I can tie in the after market regulator. Has anyone done this before? I am going to check fuel pressure before the rail and after to make sure it is the regulator but I am 90% sure. Thanks for any ideas on this.

Get a hold of Neil Mcclaren, NM on snowest, he sent me a plate that fits with the stock oring, and just use a tight turn brass 5/16hosex1/8 inch IP tight turn 90. Also if get rid of your stocker and use just the 2 to 1 you will want it not to see vaccum, just boost, or you will see a pressure rise as vaccum rises.
