1980 kz550 that needs some help!

Well I got it running(briefly)! I had some old coils off a(do I dare say it) Yamaha XS750. I used the good kaw coil for 2-3 and two yam coils for 1 and 4. I connected the Yam coils into the appropriate points and condensor and I have spark at all 4 plugs! I ran it a couple of times for only 5 seconds or so. It didn't sound too bad, I can't expect it to run perfectly under these conditions. I think i will consider taking this project farther.

Thanks for everyones help!
