Hello everyone,
It's been quite some time since I have posted but only because I do so much riding. I have a new problem that unfortunately crept up at 330AM on the freeway.
Just filled the scoot up with premium gas and hopped on the freeway, about 2 miles down the road, scoot died and wouldn't refire. Got it home and here's the symptoms:
I have power, lights, horn, turn signals etc. Last year replaced with Shorai Lithium battery rated up to 14Ah and 210 CCA
It cranks and I have spark. I replaced my coil about 2 months ago with another stock coil. The original coil was still good, just wanted to have a backup. Verified spark by hold to body to watch for arc. Using an NGK iridium spark plug as recommended on these forums.
I have it all apart now so things are easier to troubleshoot. Replaced the fuel filter, was pretty gnarly at this point. Blew through the fuel pump, no clogs there. All lines attached. I can hear the pump sometimes after cranking, not always, but the pump doesn't seem to pull much if any through the filter (shouldn't it be full?), does it run all the time or should it be fairly slow? Perhaps bad electric pump? Can I test this with a 9 volt by jumping wires (which ones?)?
Changed the oil, fresh 15w40 Rotella T last month and it's been doing great. Been running since I got the scoot in 08, only have 6500 miles on it. Did gear oil earlier in the season, all looks good.
I did find a wire off the bottom of the carb, crimped a bit more to make it tighter and cleaned, put back on but same thing. Thinking this may have come off during disassembly.
Kickstand switch is good, lubed it just in case and can hear the switch go on/off while working the plunger. I have it out of the way for now.
I have read that it could be the CDI, checked a few tutorials and my CDI appears good. If I have to replace it I am going to go with this Hi Rev CDI (9000RPM)
My problems seem very similar to this thread, cannot find a bad ground anywhere yet and all wiring looks good. His ended up being a battery, but mine is good (swapped with another bat for good measure)
Any help is greatly appreciated. On the cusp of summer, amazing weather and I'm down a scoot.
