Alright, so today I had the chance to do a plug chop.. or two.
I put the jets in, and I raced down the street with WOT, the first three gears the tires came off the ground. I got up to 6th gear, I got about a quarter through the gear, let off the throttle, pulled in the clucth, and killed the engine....
I looked down the plugs and it still looked white to my eye, so I cut one of them down. When I got the threads off it was still pretty white, with a thin smoke ring (very faint, the color of pencil lead) it looked like someone tried to trace a circle around the plug with a pencil and did a sloppy job. It was not a circle but it was wavy, and very thin. I didn't bother taking a photo to post because it was very upsetting that my results did not match what was seen online, after I was so proud I finally got the chance to do a plug check..
I thought maybe I didn't ride the gear out long enough or I was supposed to press the kill switch with the throttle still at WOT, so unhappily I made a second attempt. I repeated the process however at the end I held WOT til the end and with the throttle in, I killed the engine, and pulled the clutch in.. I had the same results.
I don't think I am running too lean for this to happen. I am running 290 jets. Does anyone have any idea what went wrong, or other methods of testing this?
