oil pipe union
« on: 29.08. 2009 10:11 »
Hi Guys, I'm new to your site but have been lurking around it for some months now. Im trying to get up to  speed on an A7 restoration i inherited ( basket case scenario )which i am finding both challenging, frustrating and exciting. However I am so looking forward to the day i fire this machine up.
Anyway, a few details before i proceed with my questions. The bike has an engine#ZA7 8280 frame# ZA7S 1090. I have been told it is an AF longstroke.
I am unable to source an oil pipe union and am wanting some advice on an alternative for the oil supply/ oil return engine connections. Any advice appreciated.

I am not familiar with the oil pipe union on the long stroke motor, but if you are handy with a lathe, or know someone who is, it is straight-forward to machine  the unions, purchase copper pipe from an industrial supplier, and solder them together.
