I remember guys thinking that drilling a jet was a big deal. I knew JM had been running them but that 07-08 time frame was when the rest of the country got ahold of them and the rest is history. and btw 206 guys I have less then 600 bucks in my bp clone I'm on my 5th clone motor 3 of the 5 are still being used one is setting on the bench waiting to be bored out for bp motors. the only failure I have ever had was the very first one I didn't check the torque specs and the coil came loose and hit the magnet and broke the coil boss.I sold that motor to a guy who jb welded it back together and ran it for the rest of the year.
