Honda Spree and Elite 50 Forums

Probably NOT the case as it's a newer scooter, but I finally tracked my issues to a bad ignition coil on the Elite 50 I just fixed up. Maybe something like that where it makes fine contact when cold but expands and loses contact once it's warmed up?

I don't know anything about the Metros though...

Alright...so the moped needs to go back to its owner, yesterday my afternoon was comprised of putting everything back together. Once I did that (and checked a couple extra things), I figured I'd give it a whirl with the new battery and kickstarter. Well...wouldn't you know it, started up after a cou...

Sorry folks, updating this as I do random tests as time permits...

Voltage when trying to crank drops to 4v. Ick...not even to turn over the starter motor/engine for sure!

Another update - threw my multimeter on the battery this morning... No load - 13.8v Key on - 11.0v Seems like a big enough drop with essentially no load on it that the battery is junk. I also did notice that the voltage continued to drop over time if I watched it...it went from 11.0 to 10.9 to 10.8 ...

I tested both the old and the new coils for resistance. I have a cheap multimeter, but I think they seem good:

Resistance across probes: 1.0
Resistance across old coil: 1.1
Resistant across new coil: 1.2

Can I do straight math there? 1.1-1 = 0.1 ohms, and 1.2-1 = 0.2 ohms (both within spec)?

Okay...so looking at the manual, the possibilities are: 1. Faulty spark plug (unlikely) 2. Fouled spark plug (unlikely, plus I just cleaned it off) 3. Faulty CDI unit (maybe?) 4. Faulty alternator (unlikely) 5/6 - spark plug wire/ignition coil (unlikely) 7. Faulty ignition switch (unlikely) I'd lean...

Found my spark tester...all I'm getting is a thin orange spark, so I'm thinking this is the culprit (again? still??). The cable is brand new, but it is a $12 cable off Ebay. What else should I be looking at prior to replacing the cable?

Well...here we go again :) Went to start putting it all back together today - started it up and it was idling high (2300rpm). Shut it off to make a couple adjustments, and now it won't even start back up. Let it cool off...no go. Of course, I can't find my spark tester right now, so I can't verify t...

Yep - and the silly thing is I have a nice spark tester here and should have gone there as one of my first options...live and learn I guess!

So, was that nasty coil lead the culprit ? Mike...I would say a qualified "yes". I can't be 100% certain since I replaced several other things, but it's what seems to have fixed the issue. I'm sure nothing else I did hurt anything, per se, but the coil was most likely the culprit. I order...

Ladies and gentlemen... We have liftoff. Needs a little tweak on the tuning, but she's alive!

...what was it?

So with that said...does anyone know which coil I would need? There's two listed at Partzilla:

30510-GS7-505
30510-GS7-950

Thanks Mike! So, I did have another discovery this morning. I took the day off to work on it, and have been cleaning everything up as I went. I replaced the spark plug and (silly me) for the first time took a look INSIDE the spark plug cable, to notice that it's missing half the connection and it's ...

Okay... Not back together yet, but I figured while I'm cleaning it up I might as well check everything. Does anyone know offhand what the exhaust should weigh? I pulled the whole thing (muffler+pipe) and it's clocking in at 8 lbs., 4 oz. Seems on the heavy side? There was some oil on the output to t...
