Hello gents, more 350f problems:
Took a ride last weekend and 20 miles from home I experienced extreme power loss going up hill. Found a safe spot, shut her off and did the standard checklist; coil leads, plug wires, fuel flow. All were good and after 15 minutes of kicking rocks and my helmet around I gave her a romp and she fired up no problem, banging on all 4 once again. Until about two miles later what felt like two cilynders cut out again. Let her cool off for ten and bam, back on all four. Once I limped her home I got to diagnosing and here we go:
When cold all 4 cylinders have fuel and spark , no problem. Once she warmed up 2 and three cut out. No spark. Both coils are brand new and after poking around with a test light and reading some threads on here about the Dyna ignition I narrowed it down to a bad Dyna. Picked up a new one at 4 into 1 in San francisco as mine was years passed their extremely short warranty period. While I was bleeding money I went ahead and ordered two new coils from DCC. Not dynas, just the $30 5ohm ones they sell. Slapped it all together today and feeling like a heroin addict needing a fix i geared up and hot the road. She fired third kick and ran like new. Until 2 miles down the road when 2 and 3 cut out. This time though, full spark in all 4. So I'm lost . my next move is pull the carbs and check for flow or a loose jet but I wanted to see if anyone has another idea... Thanks guys.
