Here is my challenge

[bigkahuna427]

I am new to the forum today but not a nimby. I am an ASE certified master auto tech and have done my fair share of fixing stuff over the years.
Here is my story. I go to a little tropical island in Florida called Sanibel where the speed limit is 35MPH everywhere. It seemed like a 49cc scoot would be perfect. I am only there a few times a year for a week or two. I searched the area CL for two weeks and was striking out. I missed out on a '05 Zuma for $100 by an hour on CL. Finally, I picked up two scooters that are real junkers for $150, however, it was the day I needed to fly out. So, I really could only get a few hours in to survey these things.

These are '03 Geely scooters 49cc 2T, 2 stroke, oil injected, jug stands vertical. Other than color they look just like the silver one at the top of this webpage. Problem 1 is these things are weathered bad problem 2 very low quality. I am going to have to put quite a bit of effort into this project and in hindsight I am sort of regretting buying them after I made a list of parts and repairs after just a visual inspection. To my eye the wiring, lighting, body panels are of such low quality this has to be a prime example of some of the lowest quality chinese scooters I have read about. I have a good idea what I need to do to get these running but have a few questions and I am hoping some of you guys experienced here on the forum can help. The guys over at scooter dawg said there were 2T fans over here. I have poked a round some and there seems to be some really great info up here.

It is my understanding these things are made by a few manufacturers and then sold under a host of different brands
Are Parts actually interchangeable between brands? It seems many of you guys refer to your engines and scooters as maybe an engine code? So what configuration do I have here and where did the original design come from? I need to understand this to source parts.

These scoots have very low mileage both are under 300 miles or KM on the odometer. They are weathered bad and sitting for most of their life probably outside. The gas tanks, one had rusty water the other gummy sludge. I have already cleaned the carbs. Tanks need thorough cleaning new filters and lines. I am thinking for good measure I would clean the oil pump tank and lines and change the oil in the final drives. I did not have enough time to check for spark or even see if the electric start worked. The engines do have compression.

So, here is my challenge. I am in Maine the scoots are in Florida. I have plenty of tools and supplys here and barely an adjustable wrench there. Basically I want to gather parts tools and supplies pack a suit case and go there to strip these things down to the frame and go through them. Other than the common tool set and tools what should I bring with me, anything special? What other repairs or mods should I be looking to do? What are common failures for these scoots?

Sorry for the long post. I am ususally a pretty good contributor to forums and will probably do a diary of this project here to help others. How do I post pics? I hit Image but it did not pull up a window to attach it.
In advance thanks for your help....

You are correct that a lot of different brands are made side by side in the same factories and badged or re-badged by distributors or whoever. For that reason, yes a lot of parts work from brand to brand and model to model. One of the most important things to do when looking for parts is to look for measurements, detailed pics, and any info you can find to compare with what you have. Parts for scooters with the same engine code generally work, although there are some engine families that have differences in many parts.

I'm not 100% sure, but I suspect you have a pair of D1E41QMB powered scooters. The D1E41QMB/1E41QMB/H1E41QMB engines have vertical mounted cylinders as you describe and they are 2Ts. They have a chain driven, single speed, transmission, as opposed to the more common CVT transmissions found in the majority of scooters. That's one of their downfalls, as it doesn't allow for much tuning. Another downfall being that there aren't many performance parts for these things, and parts in general are harder to come by. These are actually pretty undesirable scooters. They can be OK if you only want transportation, but if you have any desire to upgrade them or go above 30-35MPH, your best bet may be to see if you can sell them off for the same amount or maybe split them up for $100 each. I've never rode one, but I don't believe the acceleration is very good either, again thanks to the single speed transmission setup I believe.

Here are a couple of spots that do carry parts for that style of engines. The pics may ring a bell?

I'd suggest changing the transmission fluid as well (not just the final drive) since that model uses oil unlike most. Here's a tutorial...

Might wanna adjust the carb...

Thanks for the replies and welcomes. The info you have provided looks pretty straight forward. Question,, the rear wheel is that splined? Will it slide right off or is there a tapered fit?
The picture on scrappy dog seems to be what I have the side cover is definately it. Carb on front and exhaust to right rear side. The jug may have even leaned back a bit. They mention running ATF in the chain drive. I was thinking of something lighter the gear on the sprocket just looks like a tranny gear and in the automitve world ATF is somewhat common for manual transmissions. I am really fine with 35 MPH although at 6'3" 260lbs I doubt I am gettin' there. It would be nice if there was a tweek or two I could do to get a little more out of it. I did ride an Eaton Beamer and that was a pretty OK bike very smooth and responsive. The quality was all over the Geeleys i have now.

My coil only has one wire for the primary circuit and that made me scratch my head a bit. I am more familiar with automotive stuff with two wires where one side is powered and the other is turned on and off by points or a module or ecm. So, how does that work.

:welcome:
the pickup located by the stator sends a signal to the cdi and it in turn sends a signal to the coil thats grounded to the frame. thats why only one wire is needed, pretty simple system actually. but just so that your forwarned they are addictive.

[90GTVert]

The wheel is splined, but it's not tapered. Goes on and off easy.

There is a BBK for this engine, but it only takes the bore up to 43mm, from 41mm stock. Otherwise, you'd need to do carb tuning, port work, exhaust work, or whatever you can come up with .

My advice would be to not I repeat NOT get those scooters. They're slow as hell and a pain in the ass to fix. You are better off spending your money on a new Chinese 50cc cause they are faster and easier to maintain and you can change some weights in there to make 'em quicker whereas the scooters you are looking at buying don't have that feature. The drive train is un-tuneable on those Geely's. Parts are plentiful for the 4 strokes too.

I still can't get my head around the one primary wire for the coil. The coil is basically a step up transformer and needs dwell time to develop a magnetic field. If the trigger or swiching device is a control module (CDI) that they are tuning the primary winding on and off than they are actually doing that on the powered side rather than the ground side which just seems weird.

Thank you your info is hitting the nail right on the head!

I already have these so dumbass mistake has already been made. I told myself when i bought them if I had to get rid of these I could part them out, sell them on Ebay and make a few bucks. However I do need something to ride and this is a small island 35MPH only. I have been using a bicycle so anything with motor would be an upgrade. I guess I will have to keep this really cheap as i probably wont get much for these when I sell them.

[bigkahuna427]

So, my next question. If I were to sell these seems like I need to know what to stay away from for another purchase. What should I look for or stay away from in an elcheapo 49cc scoot?

[90GTVert]

Well, the bad news is you've just bought two of the worst possible Chinese scoots. The good news is you've just bought two of the worst possible Chinese scoots, so there are an awful lot of scoots that would be a big step up. lol

I would advise sticking to the most common styles of scooters for what you need. That would be the GY6 50 /139QMB four-strokes. They should be capable of 30-35MPH stock, and if not we can help you get them there. Parts are very common and you can find them very reasonably priced. The scoots aren't too hard to come by in most areas, and with some new models even selling online for as low as about $500 you should be able to find a deal if you look for a bit. The 4T gets better mileage than the popular 2T.

If you would like a little more power, you might wanna look for 1E40QMB /Minarelli / Jog powered scoots. That's what was in the Eton Beamer you rode. They are capable of the 35MPH limit and beyond in stock form. Parts are still easy enough to get. There are quite a few of these scoots, but they are becoming more scarce, as are all 2Ts.

There are other good scoots, but those are the most popular. If you get a chance to pick up a Yamaha or Honda scooter for a good price, they should be a good bet. If you find a Kymco cheap, they are really good scoots. There are others, but that's what you are likely to run into.

Here's a little more reading on scooter purchase considerations in general that may be of some interest...

Well, I don't like the good news or the bad news but that was a funny to put it. The Eton Beamer I really liked and the guy would not go below his asking price of $450. I made him an offer he said give me a few hours to think about it and when I came back he sold it for the $450. Maybe that was already the dumb price for that scoot. I was really nice except for the broken fairing on the front.

If I parted these things out could I make money on ebay with them? I know I can get theses things running maybe I am better off doing that and selling them before doing the tear down and cosmetic repairs to the body panels and painting which will take all the time. What do you guys think?

I am certainly more of a 2 stroke performance kind of guy. So, I went to one of the scooter parts suppliers and came up a list of manufacturers that had the Minarelli Jog (or what ever it is called) engine and came up with this short list. Do you guys have others? It might help to have key words when doing a search.
Malaguti, Yamati, United Motors X-Speed, Aprilla, CPI, Benelli, Vento, Eton, Adley

I think you would get a better profit by getting both scoots running (assuming nothing major is needed) and cleaning them up the best you can. Then sell them separately to make more profit.

There would be a LONG list of all scoots with a 1E40QMB.

So if I am looking at one of these scoots what would be the quickest or easiest way to identify that engine?

[90GTVert]

Hopefully it will have the engine code "1E40QMB" on it in the rear of the CVT trans area, up top, just ahead of the shock mount. Also, look over pics of these engines and you'll have a good idea. There are TONS of pics of these motors all over this site.
