Gasgas needing rebuild fse 450 sm
 

Ok I just got the charging system back together rode it now makes a bad sound, I know when the charging system went bad the bolts backed out tore up all kinds of metal , probably kilt the whole motor , in luck I have a o5 motor that skipped timing , love the bike too much to throw it away or part out how can I rebuild it , I hear drz got same set up just about, is this true and does it work?
