I,m sorry to post this, on a goldwing forum but I don't know where to get information, I used this forum to help me with this mod, not much info on this type of modification on a inline four, but the firing order and piston pairs up and down seem the same. Anyway I used the vw manifold and had to widen the mounts on the escort carb. This is a bobber build and is the 10speed model so there is lots of room.The spring is out of the power valve Anyway it runs at about 1300 and hunts up and down 50rpm and is visibly rich, revs very fast and is a bit rich in the rev. The jets are as follows primary, idle 60, tube x05 main 105, air 160
secondary idle 65 tube t02, main 100, air, nothing on it but larger than 160, I switched air jets and it went to black coming out the pipes, switched back and then switched main jets and got the idle down to 1300rpm. In my own mind a switch to a primary jet of 45 or 50 might help clean up the idle and put the 60 in the secondary. Also maybe a drop in the mains. Anyway I will post a few pictures this evening of the bike and mod. The cb1000c is a 1983 and has a longer stroke than piston diameter and air cooled. My questions are do you weber gurus agree with the jetting and does removing the power valve spring totally immobilize the valve
