Hello, i am not at home right now but need to know what is the correct size and thread of the rear gas line fitting on a 250EX ? I want to eliminate the screw clamps. I am thinking metric? Ski

Unfortunately, there have been a few sizes used, so your best bet will be to measure what you have. There is a thread on here somewhere listing a few of the sizes. From what I understand the newest units use a CGA fitting, while before that is was a mix of metric, BSP, NPS, NPT, etc.
