For those kind enough to offer help just thought I would post and let you know I am 99% sure its fixed.. I have to test ride the bike when it stops raining but it sure sounds like the"old" bike before this issue..
Took the carbs off again, and did a full strip.. the only thing I think I spotted was the small diaphragm I think is an accelerator pump? might be wrong, but that has the smallest of holes and I am pretty sure it was not clear.. anyway I blew it all out and just started the bike and the pops gone, no backfire at all now.. I put a shim under the needle to richen it up a bit and once I ride it Ill check plugs and see if its OK or needs taking out again.
Thanks again.. hope this will be the end of this problem.. if not, Ill be back
