sorry to hear of continuing difficulties.
I can't remember if you sent the petcock for a super clean/review...you are welcome to do so at your convenience, on me, no $$ involved.
I can't help but think there is some previous assembly error involved...a blatant vacuum leak or somesuch.
Do you know the previous owner and what he may have done or attempted to do? Did this bike run properly at any time during his ownership? Some history may be helpful. Has engine ever been (even partially) disassembled?
Valve timing, cam chain tensioner ever disturbed?
A compression test, if you can swing it, a good idea.
Spark at both plugs? Air passageways clear?
PM,phone, text or email always available for you.
