Hey guys, I have just joined after perusing your forum for many answers over the last couple of months. Love the forum and the great advice going on here!
I have recently inherited a 'recently running' 1983 XS250 special, to add to my collection of not yet running XS's. It's the DOHC YICS model.
I started with the usual stuff, ultrasonic cleaned the carbs, inline filter, new plugs, new oil. It WILL NOT START. unless I spray it with 'start ya bastard' an ether spray, then it fires instantly, I have to keep the idle speed at 2000+ RPM and it will run all day, as soon as I let go of the throttle, she dies. Even when warm, it won't start again until I spray it again and then it starts straight away. Any ideas?
