YZ125 jetting questions.

Ive done everything. i really am starting to think its electrical. I get great power up until just after the powerband and it just bogs. It feels like its not getting spark and it cant burn the fuel. Im going to check all the connections and see what it can do.

If you are worried about the electrical, try a simple spark test. If it sparks a nice bright blue, then its not an electrical issue. If its dull yellow or worse, change the plug or look at the stator. Sometimes it can get build up that prevents it from generating a nice spark.

i got it figured out. When i first bought the bike i messed up the stator being a dumbass. Anyways i bought an 06 stator and the cord was too short so i had to splice in the 05 harness to make it long enough to reach the cdi box. When i spliced it i used krimp connectors, and one of those had come loose causing my whole problem with jetting. I took it all apart and soldered the connections and it runs like a completely new bike. It just keeps pulling.

Thanks for all the help guys now it runs like a dream, wasn't even jetting after all.

Never use a normal crimp on a dirt bike.
Too much water around that will get into the electrics.
glad you fixed the problem.
Lesson learned.
