We'll I just replaced my rear head because the old one had some damage to the cam journals from someone leaving the cam loose .... I installed it per the Honda manual etc and now the bike idles at about 1900-2000 and revs perfect until 5500-6k it just pops and bangs ... I've double checked everything and have run out of ideas.... Any suggestions?
