Weak Spark

Post by hondadreamca77 » Tue May 01, 2018 8:31 pm

I have a weak amber colored spark at the plugs. Have tuned everything and bike runs great. Should this color be normal. I would think blue spark. Replaced plug wires,etc.

Coil is probably getting weak after 50 years..

If the bike is, as you say, running great, there wouldn't seem to be a problem. If it were mine I would be enjoying the ride irrespective of the spark colour. Just a personal view, you understand.

Good advice, if it isn't actually broken don't try and fix a (none existant?) problem
