I bought my 81 xs 650 about ten years ago. Drove it for a couple of years and it started missing real bad. At the time i was twenty and all i really cared about was drinking. I drove it to my uncles and it acted up again, and i said i had it with this junk, I told him to trash it. Like i said i didn't care about much. Well about eight years later i seen my uncle again and he said you know i still have that bike of yours its in my shed. So i drove to his house and got it back. Now i am trying to get it to run again. I didn't know much about engines when i bought the bike but now i am ase certified and been a mechanic for about five years. I've been reading all the posts and this site has been such great help (except for the thread about using integra piston rings, don't do it) and i am thankful. So first thing i did was change the oil, new plugs, and a new battery. I put gas in it and it just pours out of the carbs. I then took apart the carbs cleaned and blew air through. I kick it over and it will not start. I put the choke on and on the second kick it starts for all of two seconds. This bike is paying me back for leaving it to rot away, lol. So i do a compression check 100 psi on the left 70 on the right, yuck. leak down checked it and air comes through the pcv system, rings are bad. so i read about the integra rings and i order them. They are ok except for the oil expansion rings, my advice get the right stuff. Honned the cyclinders put the rings on (replaced the cam chain guide while i was in it) long story short compression now at 120 on both sides...yippppeee. Go to kick it over and same result start for all of two seconds. So redid my carbs. Then i put what i call a fire wire on it (wire in line of spark plug wires with a light that lets you know if the coil sparks) Coil sparks then goes out. Now on to my question. Reading a post from inxs, i ohmed from spark plug cap to spark plug cap and measured a out of range in a 200k setting. Is it safe to say my coil is bad? Any recommendations?
