Hi all, I have been reading a TON of threads over the last few weeks and decided to pull the trigger on a 1980 XS650. Amazing how much great info is on here! I got a great deal on the bike from Cycle Heap in Portland, OR The PO sold the bike to them because he couldn’t get a spark. When I stared the tear down today, I seemed to have found the problem. There is a Boyer Bransden advance unit, but no red or blue box! Interestingly, the stock TCI ignition is there, but no stator pickup! The bike also has what I believe is a Mikes high output dual coil. I’ll verify that when I get a new multimeter (mine broke today!). Anywho, I guess it’s time to decide if I want to source the TCI pickup or the Bransden unit. Thoughts???
