Thanks for listening,
I've certainly had my share of electrical problems in the past 50 years or so but this one bugging the heck out of me.
I have a 1986 250ES 3 Wheeler in for service and when the customer dropped it off it ran and purred like a kitten. Well it sat in the spot he parked it for 3 days before I could make room on the table, I went out to bring it in and would not start, I pushed it in and up on the table and found that we had no spark . I've gone through everything I can think of so far. The unusual thing is that if it sits for a day or so I'll go over and check for spark for the hell of it since I have the spark plug hanging out and grounded so I can see right away if its there or not and low and behold it has spark, so I put the plug back in and it fires right up , sat there and idled for a couple minutes and even took acceleration without a problem, then all of a sudden within 2 minutes it shut down and again had no spark for the rest of the evening. it has done that twice so far. I have replaced the battery, spark plug , coil and cap. I'm thinking that the pulse generator might be giving out but the occasional spark is throwing me. I've tested the CDI as best as I could and unfortunately I don't have a known good one to throw in there for testing purposes. Sorry for the long Rant but has anyone out there have any ideas that I might be over looking ?
Thanks in advance.
