Not sure what vapor was. I assumed it was water and was quick to type. I have never delt with a twin before other than a car but the more I think about it it could have been position of piston in the left side. i did not get a smell. New bike very curious. I am one not to leave things alone. Compression is 130psi and 128psi so we should be good for the season.
She runs good now.
I have a new reed cage and reeds coming, twin filters, TORS delete with screw and twist (thumb it too awkward for me), a few more jet sizes, tires. Its got pipes now (pro circuit)
I will take the advice and wait for the season to come and go. Take it down and bend over.
What else is recommended?
I was thinking to advance timing?
