Was returning from the grocery a few evenings ago. I had a nice cruise going then... nothing. Engine stopped firing and I had to coast to a stop and off the road. Luckily I was only about 1/2 mile away. I checked all my electrical connections - they all looked good - and I pedalled home.
So I'm thinking a carby issue - maybe the jet is clogged? Had fuel in the float bowl. All fuel lines intact and flowing freely. I even put in a new, smaller jet to help lean things out at WOT.
Put the carby back together and went to ride. No go. Maybe 3 or 4 pops. But mostly just getting cold puffs of air out of the exhaust.
Pulled the spark plug, an NGK, which looks pretty damn good even after thousands of miles. Pedalled the bike and touched the plug to the cylinder fins and all I could see was weak, very sporadic sparking, when there was spark. Tried the same thing with a new NGK spark plug, and the same thing. I tried to shock myself with the system (it should jolt the bugeezus out of me!) but I could feel some electric but not much.
Tried again, last night in the dark, same thing. Got a surge of spark at the end of my test and that was all.
I am wondering if you can fry the CDI by using this spark test method?
By the way, I have ordered a new CDI and a NGK plug wire.
Thanks,
Timbone
