First clean out the carbs for kicks, as one carb may be slighly off (lean). OR the timing may be off in that cylinder. Points or EI?

Points at this time, they have been very reliable so far. The plugs are burning the same.

Well one cylinder got hotter than the other. Did you just run it or did you take it for a ride? If you just sat and let it idle you may have started to overheat it. You need to get it moving down the road to get an accurate plug reading.

Put about 20 miles on it, I will check the timing, thanks for the input.

If it still has the single breaker plate I'd replace it with a >68 breaker plate ass'y to ensure the timing is correct on both cylinders. Just a couple of degrees off make a difference on these bikes, especially with today's gas.

Save the single plate breaker for posterity - I have it on one of my '66's just to keep me in practice fiddling with the point gap to get both cylinders spot on :>) - but every time I set the timing on it I swear I'm going to install a dual plate point ass'y
