[steeler2169]

lean motor... if he dont fix it soon. Tell him he better injoy his motor wile it last.

agree to the first 2,might have timing advanced to much or could be too much compression as well.

Tell tail sign of detonation. Findout his compression, timing, dome size, and elevation and report back.

As well as what kind of fuel he is using...etc.

 

Before he runs the bike again, this needs to be addressed

I agree, detonation, and the condition needs to be corrected immediately...
