The thread where I ask questions about my new R65L

Cold hard starting, do you have the original black and gray ignition coil

[misterpepper]

Yes, but my new red Dyna just showed up in the mail today. I ordered some new wires from bmwires on eBay as well, since my existing wires measured 9.5k ohms and 7.6k ohms and were the carbon core type. New wires are copper core, silicone jacket, with 5k resistor caps. I'll install both when the wires get here. Spark should go from kinda white to fat and blue, I hope. 

If my spark is fat and blue at .025" gap, would it make sense to open up the gap a little, say .032", as long as the spark remains healthy? What's the widest gap you guys are running?

I tend to think along the same lines but it's curious that BMW didn't do it when they changed from points to electronic ignition. Even though the new 1.5 ohm dual output coil would have more than doubled the spark energy they left the pug gap the same. Because I couldn't understand why they left the gap unchanged I once asked  Snowbum directly why that was. The only explanation he gave was it allowed for igniting weaker mixtures.  That's true enough as the optimum strength for easiest ignition is very rich at 11:1 and carb settings did weaken about that time to meet emissions targets.

I would  still at the very least open up the gap to the maximum end of the range specified which is 0.028"
