No problem Doug we're all up here to help each other. You may want to check
your gas tank for rust. Pull the fuel petcork off and check the screen. In
most case when you were slow jets get plugged up for no apparent reason.
Most of the time it's microscopic bits of rust that of gotten past the fuel
sock. You might want to pick up an install a in-line fuel filter.

Thanks for the replies.
I removed the carburetors again and removed all the jets. pushed 
small wire through them and blew them out with air.
Didn't really see anything in the jets but it did the job.

Bike is running normally again.

thanks again
