i had the same issue with mine and came to the conclusion that it had nothing to do with the bucking bar, pads or adjustment... it's simply with the amount that we use the clutch, specially for starts from a dead stop where the clutch actually spins the bucking bar, it wares out the sides of the clutch shaft to a point where the clutch arm simply pushes the bar to the side rather than into the shaft... it's a $5 fix for the new shaft from bike berry on ebay... not sure what they charge on their actual page... but i'm pretty sure that by replacing the shaft, then setting everything back to relatively stock settings, you should be good to go, i'll let you know for sure in a week or so when mine comes in... i too replaced the bucking bar as well as the cam due to the fact that they were completely worn out, but when replaced, the problem didn't go away, it actually seemed to get worse... that was when i pulled it all apart again (several times) on my ride home and realized that it was the walls of the shaft that had worn out almost 1/16" all the way around, so the bucking bar would NOT sit straight... i don't know if anyone else has had this issue or not, but as i said, i hardly ever pedal start aside from actually starting the motor... once it's running, i treat it like an actual motorcycle for starts, which leads to excessive ware on the shaft walls...
