Hello everyone So, I am a little stumped on the behavior of my 02 yz 125. After a top end rebuild, new gaskets and crank seals, repacked muffler the bike still seems to run rich, based on the pic of the plug, the bike seems to still be running rich? Here are the settings on the bike: AS is 2.5 turns out Pilot: 25 Main Jet: 415. It started just fined earlier today, and I rode is for about 5 minutes, it was hauling!! My son then came home, started on first kick, i did notice there seemed to be a constant white smoke coming from the pipe. It started up with a high idle, but then calmed down. He rode it around for about 10 minutes and it was riding fine. He was riding in 2nd gear and cruising and then it started to bog out and then died. He tried to kick start it, but nothing. He and his friend then tried start it from pushing it then popped the clutch and it would never turn over. This has happened before and once I replace the plug, it starts right back up. I thought by lowering both the main and pilot jet it would help resolve these issues. Anyway, any tips would be VERY helpful and appreciative. Thanks!
