Electronic ignition

[Ashdowner]

I've had 2 CB550K3's - 25 years apart. the first one had Boyer ignition and it went like a dream with absolutely no problems. The one I have now has a DSS unit in it and it also goes like a dream - BUT......since I installed it my battery discharges if I have my headlight on. I know the Boyer system draws 1.5 amps (e-mail this morning) and I'm waiting for DSS reply to tell me how much theirs draws. If it's the same then it's obviously a charging/battery problem. The bottom line though is that in terms of performance I believe the units to be equal.

I bought a Boyer unit in the end. It is all electronic

  I run Boyer ignition,and  H4 halogen  headlight,

 normal open road riding its works great,but if your stuck in town traffic for long,it can cause an issue,

I have the same problem. I've made a difference though simply by putting an LED stop/tail in. I'm also going to get LED's into the indicators (ok not a great win per £ spent) but if I'm in traffic mine suffers as well and the indicators don't help. Also going to get an LED headlight bulb which would make the biggest difference but I'm struggling to understand which one is best.

You'd need to check if the Evitek G6 H4 (with shield!) would be avail for LHS traffic...
Dunno if the heat-sink/fan assy will fit the headlight bowl though...
