300ex hot cam problem,,, need help asap

[honda300EXtreme]

i just installed a stage 1 hot cam into my 300ex today, and i took it around for a very quick spin, it was quiet and running great,

but by the time i got back to the house it was making an awful knocking noise, this noise is not normal,,, so i tore the head off and found the sprocket bolts to be loose, so i tightened and fired it up, it sounded fine, then it started making the noise again, so i have no idea what the problem is, the valves are adjusted correctly, and the bolts are not loose, i did notice that when i checked the timing it was 180 degrees off, so i set it correctly and it still made this noise..

please help me out, im a little confused :confused:

thanks for your time
