2007 Speedee 150 - Rebuild and Rehab
 

Hello all,
As you may know I have been rebuilding a Zongshen 200GY over in the Enduro section and asking lots of questions. Being a glutton for punishment I purchased for cheaps a Speedee150 4 wheeler, exact manufacturer unknown to me.

I'll post some pics once it is up in the Imaginarium aka the shop.

It has the following identifiers I can spot:
Left engine, bottom- 1P57QMJ
Number: 70000309
Faded metal plate-
Date 2007
Speedee 150
GY6 .75L
Cylinder Head has Name RONGA imprinted on it.

So there it is, another abused and beat up machine needing some care. As with the Zong there are tubes that go nowhere, and it has a broken ignition switch, and no key, of course. And the icing was the chain fell off while we were loading it in the truck. So I have a little bit of work to do on this one now as well before we can start having fun with it.

I guess the first order of business is acquiring resources for diagrams, parts lists etc so I can get this going too. Is there a manual for this, or at least for the engine so I can get started with routine maintenance stuffs?

Thanks!
Jim

The GY6 is a nice common engine. Parts are everywhere.

Well thank goodness for that!! As with the Zong I really need a "what does the thing look like with all the stuffs on it?" kind of picture (the atv sitting over here I mean).

But I did find a slew of GY6 service info at this website and downloaded every document there which appears to be mostly a single manual.

Can anyone tell what the manufacturer of this 4 wheeler is? The only time I find Speedee150 and a manufacturer is Shineray. Is this it?

I'm headed up to the shop to take some preliminary pictures and start assembling an 'obviously missing thing' parts list. Talk to you soon!

Jim

I'm not sure that a manufacturer would be a benefit to you, assuming we could even figure that out. Most of the China stuff is not specific to one brand, and we're usually able to source parts for whatever we're working on.

When you post a pic, we'll be able to zero in a bit.

:lol: That's awesome! Mine is the Lab.

I won't believe ANY thing other than factory data: http://shalaa.pixnet.net/album/set/813575
Kymco GY6D "ancestor" -Valve clearance: in/ex is 0.12mm
The water-cool "JF03E" -in/ex is 0.1mm http://www.ride-inc.net/file/32/data.pdf (they're authorized by Honda)

Ok here it is in pictures!
 

This is the ATV we obtained. It was originally Blue. A headlight is missing, the tail light has been cut at the light. The starter relay sits outside the frame on top of the CVT. The Ignition switch wiring is hosed and already hacked. The wiring from the starter is bad as well. They did manage to get it started while I was standing there which is when I noticed the acorn nuts to the exhaust are missing. Oh and of course the seat is super shot. The places where you put your feet used to be webbing but are rotted out. The airbox was wedged in there turned 1/4 from the way it should have been and the carb clamp is missing. The grips need changing as well. There's some hoses that are just broke and hanging in air so I'll have to investigate that. And the Right hand Flywheel Cover is missing.

So that's the short list. The future of this ATV has racks on the front and back, front headlights, a trailer hitch, and a winch. Tah Dah. I also want to change the 40t sprocket for something bigger to make this more of a hill climber/slower ATV too. Speaking of it'll need new tires as well.

There we are. Now for some preliminary pics:

Yes you can ditch the emissions crap you have circled.

It is missing the cooling shrouds that wrap around the cylinder.
Take a look at this one. Shows the fan and cover for the forced air cooling.

Lots of parts here.
They have the cooling shroud, fan, and cover that you will need.

In picture 4 where it connects to the carb intake can I get a little vacuum plug for it and toss all the other tubes? Ok, the thing in picture 5 is to be removed.

I'll be reading over the websites this evening, thanks for the links all!

Jim

You don't even need a fancy vacuum cap. Just cut the intake tube hose a little shorter and stuff the bolt in it. Voila.

Need need need a wiring diagram
 

Ok good and easy. I'll start there.

What I really really need is a wiring diagram. I have googled and found a few GY6/1P57QMJ diagrams but do not look familiar so far. The starter wiring is wrecked and I want to move it off the handlebar anyway. Same witht he key ignition switch, it too is wrecked and already hacked down to two wires. I have a picture too.

On the ignition switch, can I connect the two remaining wires coming from the harness to an on/off switch and be done with that part? They are red and black. Picture below

I'll take a better picture of the left handlebar controls area because there are a bunch of things over there I don't think are on this atv anymore.

Thanks!
Jim

If it's in std Honda color
red = battery + to lock (ign s/w)
black = + after lock (ign s/w)

Quite easy to follow if divide to different function:

Perhaps HB could just point to a Taobao wiring harness for you. It would be much easier to start with good wire.

http://item.taobao.com/item.htm?id=39016239977
Main 主 wire 线 is enough if NO horn / light

Added to the list
 

Thanks! That's not a bad idea for less than $10. Ok, wiring harness added to big list. I do like the diagram too though, even though I can only read the pictures I can see how it is supposed to be wired so I can get it going now.

While I'm looking at all the electrics would it be beneficial to go ahead and get an upgraded Carb (lose the auto choke, get manual choke), CDI, Coil, Spark Plug, Sprockets (larger than a 40t), exhaust etc? I'm not sure I am ready to mess with boring the cylinder head or changing the weights in the CVT to get more performance, just bolt on stuff for now.

Thanks!!!!
Jim

If you can get all of that stuff for cheap, it would be good to have, especially the CDI.

If you decide to increase displacement in the future, there's no boring necessary. Replacement cylinders in larger sizes are available. BTW, I'm still using the auto-choke carb, and it has been terrific.

Check these http://www.motorfans.com.cn/bbs/t_101940.htm if auto-choke f***ed

The auto choke works fine for me too.

Hmm, ok then good, I had read a couple of "upgrade your atv performance" type posts in my initial research of them and the carb was something that was suggested as a replacement. And this ATV has already had the electric throttle wires replaced as it's way newer than the rest of the wiring harness. If it's not needed really for jet replacement ease, bigger barrel etc then I'll leave it. Hurray one less thing!

Thanks!
Jim

CDI question and pic
 

Ok so speaking of upgrades and the CDI. The one on this bike has a wire missing, I think. Does this mean something? Like it was just removed or was it never there? I am still learning what is normal and what's not. Is this CDI/wiring normal?

Thanks!
Jim

That motorfans link was cool, those types of posts always teach me how fearless to be with stuff. Very cool.

Thanks HB

That wire typically goes to a kill switch, but your quad might be wired to simply cut power. Don't worry about it for now.

DC CDi ? http://www.mobile01.com/topicdetail.php?f=266&t=2234502

I'm very grateful that you take the time to share these links with us, but I can't make any sense if it. Lines like these confuse me:

"DC CDI no power to change the same can step on hair .."

"I really never thought such a change can admire the landlord!"

It seems that someone found an adapter to change from an AC CDI to a DC CDI, but I'm really not sure. :D

F*** the communist. http://en.wikipedia.org/wiki/Simplif...ese_characters
NO one use "handicapped" for most important matter (1st month Celebration / wedding / funeral) in my hometown.
發 isn't 髮. "Handicapped" shares the SAME 发 (踩 step 發 start). The upper part of 髮 is "hair" related. Even semi-illiterate can get the idea by 1st look.

Ok, is a kill switch typically found on an ATV like a bike? On the Zong it's on the right handlebar, where is it on ATVs? Having one for the wife on the handlebar she can mash if she panics might be good forethought.

At the moment I am following the 12v current through the wiring harness having some good luck patching things here and there getting closer to a start.

I am also going to post the pic of the left controls as well for some help on what everything does-or did.

For what's up with the CDI--I'll see if I can pull any markings off of it [CDI] to see if it is a DC model. It's be replaced with a better one either way but I am concerned if there's a wire missing from the harness for this. What's the purpose of having a DC CDI vs an AC CDI anyway?

I'll totally ignore it for now, I just need to get hers going, and order a fresh harness that'll take it's time getting here.

Thanks!!
Jim

The push button is the headlight on / off switch.

This is a good opportunity to discuss what appears to be a signal light switch. That was the original intent of the design on a street bike, and the signals were activated by sliding the switch either left or right, and then pressing the switch in once to cancel.

It is a kill switch in this application. Slide the switch either left or right to kill the engine, and then press it in once to prepare it for starting again. If you fail to press the switch in, the engine will crank until the battery dies, without ever firing.

That switch has puzzled many of us, including me. I actually removed the flywheel to examine the stator, since I couldn't get any spark when my quad was brand new. I accidentally figured out how it worked, well after I had torn everything apart. Live and learn.

Thanks HB. I saved those pics for future reference.

I love diagrams! Thanks HB.

Weldangrind: I think I was on that trail. I opened up that control and saw the black/white wires which made no sense as those are kill switch colors and that the starter was all connected through it as well. Now, from a previous picture does this mean probably that it is disconnected because of it's missing other end at the CDI? I will continue hunting voltages and test these controls too. And start a wire map...

Woohoo for learning about stuffs!! Thanks again all!
Jim

One never knows the ways in which a harness may have been butchered in the past. The only solution is to unwrap the harness and follow it.

Roger that I'm all over it! I am happy to be getting this experience, daunting it may be at times, it will help later troubleshooting it and the bike. :tup:

Thanks!
Jim

Is this what you mean by a piston upgrade?

This is what I was thinking: http://www.ebay.com/itm/GY6-63mm-Cyl...4b6ca5&vxp=mtr

Humanbeing, do you have a 180cc GY6 kit link for Taobao?

61mm kit: http://item.taobao.com/item.htm?id=10167875713
Seller warned to EVERY guys:This product is 65mm. W/O "chopping" can't put in std 125 (61.5mm) / 150 (63mm). Hack job isn't fun: http://www.motorfans.com.cn/bbs/view...authorid=75082 . W/O proper knowledge may kills it

Search" "63" "gy6" in TB. Most kit of this size are made in TW . Fleabay's price is very reasonable.

Yeah no chopping, I won't attempt that. :ohno:

Good, I have added the 3 things you listed as would be required HB, but am not sure about the 0.00 price reference? "http://item.taobao.com/item.htm?id=10441654861 3 Gifts - Order via those links NEEDED/ Contact the seller "改价" (change the price) to 0.00 "

Thank you guys for all your help finding this stuff. I will post a list that I have going for an international order soon for the bike and the atv.

Thanks again!
Jim

PS I registered with Taobaotrends and am getting really excited!

http://zhidao.baidu.com/question/97678388.html -Ask the agent for details. (they're fed by commission, so ... ) Total of "3" is <$1. Gift or NOT dose't matter at all.

Racks and Plastics for ATVs?
 

Thanks for the tip HB!
I would like to put racks/brush guards front and back on this ATV sort of like the picture but I cannot figure out what phrase to ask for on taobao. Plastics to replace the racer type plastics would be good too.

Thanks! Gee, her ride is going to be way cooler than mine!
Jim

And I just failed searching for "ATV seat" "ATV saddle". How do I search for a replacement seat for the ATV?

I think I'm going to go do some welding seeing as how I am striking out with language usage today. :doh:

Thanks again for the help!
Jim
