Hello guys, i just put a new pro X piston kit in 1998 kx 250, it has tons of compression now and idles fine but when I get on and ride it as soon as I hit the gas, the bike bogs and dies. Also when I was looking though the oil glass it looked as if the oil was bubbly? Any help would be greatly appreciated! Thanks guys

What compression on this 2 stroke with that piston?
Have you checked for air leaks around the carb/reeds? Any cracked reeds?
The float set correctly in the carb? No pinched lines?
