Hey guys! I have been having some problems with my 416. No matter what I do I can't get this thing to run cleanly. Let me first let you guys know what I have done to the quad.
I have a 11:1 Wiseco piston, stage 2 hotcam, Rickys rev box, full 2 bros exhaust with 7 disks in, and an aluminum air box with a K&N with prefilter (no lid). I have a 160 main (stock jetting not any kit), a 142 pilot and the needle is on the 3 clip. I have the pilot screw at 2 1/2 to 3 turns out, the choke was out ( I have recently put it back in to try and help starting). I quad about 500 feet above sea level in 40-90 degree weather.
When I try and start the quad I hit the gas 2-3 times and then hit the starter. The quad kicks over and starts but dies immediately whether I try and hit the gas or not. Adding the choke has not seemed to do me any good. When I finally do get it running it runs fine, but seems rich from what I see happening to the plug and end pipe. I am fouling out plugs (I think from the starting issues) and I get black soot at the end pipe. When it gets warm out it definitely starts easier, but I would like to get this thing to start in any kind of weather.
Is my jetting that far off? Is the Ricky's Rev box garbage? Could it be something other than these two things? I just want to get this thing to start and run a little easier. The season is getitng ready to start so I need to sort this out. Thanks for the help guys.
