Hi guys, great forum here I have been lurking for awhile now I have my own problems. I'm familiar with the gy6 clones I just got finished with the 80cc kit on my cousins scoot and all that jazz. He finally talked me into picking up a scoot for myself and I found on on craigslist today and bought it.
I don't know much about the 2 strokes so I am going to need a hand here. The scoot was 165 dollars so I thought I was getting a good deal and would be easy to fix any problems it had....however today has been a trying one.
So the scoot is a 2003 Geely, not sure on the engine code, but it is a 2 stroke. I am having problems with spark. My questions are, Should the coil have constant power going to it? If so how much? I noticed when troubleshooting it that my coil has constant power going to it and the voltage seems to drop on when starting. There is no power comming from the spark plug wire while turning it over, or when not turning it over. If the coil has power TO it is there anything else keeping it from creating a spark?
When I say the coil has power to it, what I am refering to exactly is the white wire going into the coil, it only has 1 white wire and seems to be grounded via the bolt to the frame. Other than that, there are no other wires entering or exiting the coil besides the spark plug wire. Thanks in advance and if you need any elaboration feel free to ask, as at this point I am at the mercy of the scooter gods.
-Mike

I forgot to mention I also have it hot wired, black, black with white stripe, and red all twisted together. green grounded to frame.

Okay after more troubleshooting today my questions have change a bit. On a two stroke motor, or this one in particular. I noticed there is no CDI clearly visible. So I am to believe it works of the magneto, or stator, or whateve rits called to tell the coil when to fire. However I do not see any wires comming from the side of the engine to the wiring harness to check. How does one go about seeing if the coil is recieving a signal to spark on a 2 stroke motor?

Let me start by saying, I don't know much of anything about Geely scooters and their ignition systems. I'm used to CDI ignitions on scoots. Since there's no other advice yet I'll try to help if I can. If the coil is mounted away from the engine (as it sounds from your description), the coil should be recieving a pulsing signal. If the coil has only a positive and negative connection and it is a constant voltage it would be trying to create a spark at all times rather than at the proper time determined by a triggering device. If the coil is mounted right by the flywheel it could be a magneto style igntion system. It would use magnets on the flywheel and coil integrated pickup(s) to determine the proper firing times. Here's an example of a magneto igntion. Here's a CDI ignition. I guess it could be a magneto igntion with a remote mounted coil as well, those are just the kinds I've messed with. Either way, I have to assume that if the coil is mounted to the frame somewhere with only + and - it should have a pulsed signal. You say it has no power from the spark plug wire. Are you using a spark tester or leaving a spark plug connected and holding it to the frame or are you using a multimeter or test light or something. I'd just use a spark tester or hold the plug against the frame or other ground while cranking and look for a spark. Your coil can be getting a good signal and there could be no spark. That would indicate a bad plug, plug wire, cap, or coil. Swap the plug, inspect the plug wire and cap, and if those are alright the coil is probably bad, assuming it's getting the right signal.

Ty for the response Vert, I finally got spark today, after bashing my brains into mush and nearly tracing every single wire and taking the scoot completely apart. It dawned on me....maybe its not a problem with the scoot but my hot wire job. Sure enough it was. I just broke the ignition with a screwdriver, hooked everything back up and bam, the mighty blue spark I know and love. So now we move on from that, to getting above 30 mph.....this Geely scooter seems to be the same bodystyle as my cousins 4 stroke Tank. Any idea how I would go about finding out wich engine I have?

Look for numbers on the engine/CVT. I know my minarelli engines have the number at the top near the back of the CVT section and the 1E41's should be the same. I think it'll end up being a 1E41QMB or D1E41QMB. Hopefully I'm wrong, but if it's one of those they are chain drive transmissions and aren't known for being fast.

Well hopefully it isn't one of those, but if it is. what the hay i rode it all day today and i payed 150 bucks for it:P during me and my cousins scooter travels today we ran into some other scooterist who have another one that was stolen and returned to them in ill repair and they are going to give it to me for free!! What luck!

Yeah, you really can't beat two scoots for $165.

To dark out back, but if yourstill around vert. Would a chain drive scoot have an oil plug on the transmission? thats all i can really think of right now off the top of my head.

Ummm... a new engine???
I don't really know of performance parts for those. You can modify what you have to try and get more power. Make sure there are no restrictors in the exhaust to start. get the carb in tune. Stuff like that. Beyond that you'll be looking into porting, increasing compression, exhaust mods, etc... I guess.

Well I guess its not important anyways, just sold the scooter today for 400 bucks.

Some guys have all the luck. You looking for a new scoot now?

If you are trying to get a 2 stroke, see if you can get a Yamaha/Minarelli/Jog style powerplant (1E40QMB). You can mod till the bank account is crying if you pick one of those up.

I just want something that will do 40-45 comfortably and not leave me to get squished when im leaving a stop light. I'll just keep waiting and eventually the right bike will come along that has some upgrading potential.

Looks like I might have found a new ride, a Motomojo Uptown, 175 bucks! supposed to go pick it up today. Person said it has sat for 6 months and haasn't been started since then. Now it won't start.

It looks just like a Vento Zip (remember that if you ever need body panels or something because Vento has a nice parts page). I can't find any good pics of the engine area or specs on what it has with a quick search, but from what I've seen I think it's gonna have the 1E40QMB engine ;D.

Nice. If you run across any other 2 strokes near me that you don't want, lemme know. The gloss black scoot (in avatar) is just sitting in the corner under a cover waitng for an engine.

Alright the Motomojo is mines, lady said it didnt run, got it home 6 kicks and it started right up. Need to clean out the fuel system however stuttering after WOT. gonna drop the carb tomorrow and clean er up and clean up the lines. Whats the deal with derestricting this engine Vert? CDI clippable to remove the rev limiter?

Post by 90GTVert on Apr 2, 2009 21:25:38 GMT -5
Neither of my scoots have had rev limiters. Washers in the variator are the most common restriction I know of on 1E40QMBs. It should be just behind variator face if equipped.

Alright, did yours come equipped with an "octupus pipe" or whatever? cause mine has just a striaght pipe into the champer it seems. Trying to figure out if this thing has an aftermarket pipe or not. seems alot of welding has gone on, during the life of this pipe though. Thanks for all the replies btw, imma be dogging you hard since this is my first 2 stroke and you seem to be my greatest resource. have a bone on me daawwwgg

My stock pipe was nothing more than a head pipe (exhaust port to flange) and then a big can muffler just like a 4 stroke would have.

Well I was preparing to ride the bike for awhile today, then my CO called me and I got my orders, i'll be leaving monday and won't be back home for a year and a half...lame:P But anyways to the scooter, It is progressively getting worse and worse. When you first start it its great you can ride WOT fine it has good accel. But after that first burst it just begings to sputter and won't gain any speed whatsoever. I cleaned the carb, the lines, got a new fuel filter, all the jets are prestine. So I am guessing either the Coil is going, or the CDI is junk. I located the coil, and I'm not sure where the CDI is, but I figured before I drop cash money I better ask somone.

Oh yeah and of course I swapped in a good NGK gapped to .26 so its not the plug.

Did you dump the gas tank? Could have water in the gas.

Post by 90GTVert on Apr 3, 2009 18:33:00 GMT -5
I wonder if it could be too lean and possibly runs better at first start up with the auto-enrichener working? Did the other plug look lean when you pulled it out?

yah I already ran through one tank of gas, but I think I fgured out the problem again on my own. seems im a moron and when i was cleaning the airbox i forgot to put a small little pipe back into it. seems to be running good now...i think...still a little iffy after WOT. Maybe I need to play with the mix? I know the idle screw has a thumb twist, then a small screw in the back of the carb is for the mix right? I am adjusting the right one?
