Ok so i ran into some problems. Jetting is so far off. Lol. It was a bitch to start. Remember i got these carbs off a yz 125 dirtbike. they are mikuni tmx 38 flatslides. Anyways i got it started after about 100 kicks and didnt do much. I put it in gear and made sure all of that was good. Did the leak down, it checked out, did the compression, it was correct. So heres what i found when i opened the carbs. One had a 405 main and a 30 pilot, the other had a 25 pilot and an unknown main. I just ordered jets for it. I ordered 370 and 380 mains and 35 and 37.5 pilots. That should get me close. Atleast thats what i got from the jetting calculator on the digital toolbox.
