hi there...tore the petcock to bits everything looks great except the o ring was melted away looked everywhere for an o ring that would work and struck out any ideas guys...got to get her going quick before the snow flies haha cheers thanks in advance
5mm ID x 2mm cross section works for me. You might also want to go to the hardware store and get a slightly strogner spring for the diaphragm/

Thanks David is your bike a 1985 also where did you find the o ring im striking out here
Yep, worked on my '85. My local ACE hardware store had the metric o-ring and a replacement spring that was too long, but I cut it down to a length slightly longer than stock.
