it's been riden for a little while... This happened awhile back too, but it was down for other stuff, so now I'm back to addressing it.
Here's exactly what's happening. I'll try to be as detailed as possible.
After riding the bike for about 15 to 20 minutes, I was cruising along about 60 mph, motor humming, RPM's pretty constant and in a normal range, and traveling on a flat road. I felt a huge loss of power and I immediately started to decelerate. Felt as if only the bike's valocity was keeping it running. As soon as I got over (across 3-lanes of traffic!!) it immediately stalled out. I let it sit for about 30 seconds and tried to kick it. Nothing. Gave it another 20 seconds and tried again. This time I got a pop, but didn't run. Kept trying, after about 20 more seconds of leg aerobics it started and ran fine. High-taled it home and put it in the garage, drank a beer and relaxed. I went to start it up again the next day and I got a single, solitary, pop after about 20 seconds of trying and then nothing for the duration of the trials. Never got it running again and I'm too damn frustrated to even try until I have an idea of what's going on.
Okay, with all that being said, here's what I've checked:
- plugs look fine, maybe a little burnt, but pretty new.
- plug wires have some cracks in them. Little dry looking. Aren't very old and I assembled them from replacement, new 7mm, early Ford type cloth spark wire. I anticipate changing those immediately!
- gas tank seems to be getting enough ventilation. I have a large hole in my flip cap that should let plenty of air in. Just re-assembled my tank after a re-line and the petcock was clean (as long as I didn't screw up my 6-day POR-15 tank lining job!!)
- compression seems a little low and I'm going to check the head torque for that.
- carbs are new, so I don't anticipate any float or needle problems, however I'm going to drain my bowls and inspect them for debris.
- gas may be old that I've been using for my test trials. I'm going to dump that on my pesky weeds and refill with some fresh 91
I've had this problem in the past and it's always when it gets warm. The motor is a fresh rebuild, carbs are new, the Joe Hunt mag is new... anything else I'm forgetting? Any thoughts? I'm sure this is just something stupid, just need to know what the hell it is!
Sorry for such a long ass post!!
