Project update: Scooter is now past the point of no return. Front section has been separated from the rear downtubes.....and is ready for widening. Since I want to keep it stock in appearance by using the stock plastic side panels I am somewhat limited by how much I can widen it but after a bit of trial and error it appears that opening the frame up 3" will give enough room to get the engine in and and far enough forward to keep the wheelbase within 1/2" of stock. I don't think that will be too noticeable and it doesn't impact the rear fender mount/tire clearance in this position.
I'd like to throw out a question to the forum participants. Since this is a "project", I have a lot of leeway on all of the specifics. The next item to be solved after frame widening is the engine mounting. My engine donor scooter has a swingarm type of engine mounting arrangement. I've seen (online) other project scooters where this has been eliminated and they have gone to a rigid fixed mount. Anyone care to comment on the pro's or con's of this type of mounting? If I go to this fixed type of mount, are the front mounting bolts standard bolts or do they need to be shouldered so they allow the mount to move a bit? Thanks in advance for your insight.

Yes, it is a stock engine. Just got a new carb and cvt belt and am hoping the rest is in fair shape. I bought it used but it was supposed to be in working condition, less a broken kickstarter which has also been replaced. New tire and tube were installed this afternoon and built an engine stand so it will be positioned at correct height for mock up.

Now one of the first things I would do is to measure the frame tubes. OD and ID. the electric scooter tube may be thinner than we want for a gas scooter. some of those electrics were made with a motor that is just a fraction of the power of a gy6, there for not needing the strength of the frame tubes used on a gy6 and so on. /. john You got me to thinking about the strength of the frame tubes so I spent some time on the calculations. I only have one other scooter to compare it to ('08 Jmstar) but this is what I found: Jmstar tube is 1.325" in diameter and has a wall thickness of 0.08". Calculated out, it is the equivalent of 0.3120....square inches in actual cross-sectional steel area. My project scooters' tube measures 1.128" but has a wall thickness of .11". Calculated out, it is the equivalent of 0.3517 square inches in actual cross-sectional steel area. In this case, I am interpreting the result as more steel is better.... Spent hours on the project today cutting the original gussets and bracketing off and building a frame fixture so I can get some measurements. I have the one main gusset to remove then will be able to start the frame mods.... |

I do visualize new2scooters will have more troubles with the conversion in the frame. You will need some good welding and bending from the way it sounds. Now one of the first things I would do is to measure the frame tubes. OD and ID. Thanks for your input. It is appreciated. Yes, I am expecting some issues with converting the frame to accept the engine.....I'm going to give it some serious thought as to my options but come Sunday, one or the other should be done.... Been a "hobby" welder for most of my life. I certainly wouldn't qualify as a "nuclear power plant pro welder" but I get the job done and know my limitations. This looks to be a doable project. Will keep you posted. Been trying to post pic's but my connection drops when uploading.... |

My battery power to gas power scooter project is now in the mock-up phase and a few issues have made themselves known. The primary issue is that the frame narrows so much that there is no room to move the engine forward far enough so the rear wheel is in the correct position with the current chassis length. Basically my options are to either lengthen the chassis or to widen the area where the frame narrows..... I would like to keep it looking stock so will probably go with widening the base of the frame to allow the engine to move forward, although that is not the easier of the two....decisions, decisions.....

You are reading the scooter model number.. the engine code is engraved into the casing on the left side just below the front of the CVT. It is likely something like XX139QMB Thanks for your help. Under the layers of mud and grease was the number where you said it would be. It is a 139QMB so that will certainly help in getting the correct parts. I briefly rolled the power unit under the new scooter project (battery powered to gas powered) for a quick look/see and it looks to be a perfect fit. Should not take too much work to get it mounted. I'm going to get it up on the bench in the next few days and get it cleaned up and serviced. In the meantime I'll keep looking for a replacement cover and kickstart lever. It needs a new belt too so might as well get that ordered at the same time. Thanks again for your help. It is appreciated. Bill |

I picked up a used scooter for parts for my current project. Plastics are in rough shape but I'll more than recoup my money with wheels, engine, etc... It does need a CVT side cover as a casting detail is broken for the kickstart lever. I would prefer to keep the parts cost down and buy a used one if I can find one but is this a common problem with the GY6 engine? Should I just buy new? Anyone have any input on this? Anyone have one to sell?
One other question I have is the engine type. Engine is from Shanghai Jmstar Motorcycle Co, Ltd. and # is YY50QT-6. I am assuming it is 50cc. It physically appears to be a GY6 but how do I know? Are QMB and GY6 the same as far as ordering parts? If I need to order a new cover I'd obviously like it to be the right one the first time.....
Thanks in advance for your help.
Bill

Hi fellas, and ladies! I've been googling for an aftermarket reserve fuel tank with no success at all! I'd like to mount something like a 1 or 2 quart bottle/tank under my seat, with a manual petcock/switch that I could just turn, if and when my main fuel tank runs out on a trip. Just something that would get me another 25 or 30 miles, if I run out of gas in the boonies somewhere! Has anyone had any experience with this? I'm open to any and all ideas and appreciate any info you might have. Thanks! If you wanted to stay on the inexpensive side of fuel storage add-ons you could use a backpacking fuel storage bottle. An example can be seen here: www.rei.com/product/783963/msr-fuel-bottle-with-crp-cap-30-fl-oz I used one similiar to the photo when I was doing long distance bicycle touring. Never leaked and I always had spare fuel available for the stove to cook on...I used a 1 pint storage bottle and it fit in a spare water bottle holder perfectly. They are available in 1 quart sizes also. Plus it always was a conversation starter when I'd pull into a gas station on my loaded touring bicycle and fill up. |

Don't know how many times I have to warn everyone on here about T-Motorsports.. They are the worst company known to man. The owner Michael Teng is a piece of garbage like his company. They don't give a crap about nothing about selling garbage and once its paid for its paid for.. I again WARN EVERYONE... Do NOT buy from T-Motorsports, gold3388gold, TMShelmet.. They are all the same company on Ebay.. I found out too late to benefit from your post here. A long story here but the engine I ordered from them on ebay was supposed to be complete but wasn't. I couldn't get any satisfaction from the company, and was told I don't "need" the part as it will run without it....even though it was shown in the listing and could only return the engine at MY expense. That just wasn't going to happen so I filed a complaint through ebay. First response from vendor was as above, ship it back at MY expense. I escalated the complaint to ebay arbitration and within hours I had a link to a shipping label at no charge to me. Engine went back and funds were returned within hours of tracking # showing delivery. NOW THE REALLY INTERESTING PART...... I promptly starting looking for another engine to order. What I discovered is that 3 vendors, PCC Motors, Motor99Motor, and T Motorsports are using exactly the same photo's in their listings. Bad idea as in one of the photo's is a picture of the engine number and in all three listings, the number is the same....same number= in all probability same vendor. I wouldn't have known otherwise.... BUYER BEWARE.... |

[quote author=niedzwiedz board=customscootsmodsetc thread=5515 post=40833 time=1324625281 I was notified today that the engine that was returned to the ebay dealer under the ebay buyer protection plan has arrived back in CA at the dealer. It remains to be seen how long it will be before my funds are returned. Hopefully, it won't be too long. Great news! Funds have been returned to my account and I'm able to move forward.... Thank you "ebay Buyer Protection Plan." Never had to go to this length before to get a refund. Sad to note that had they only forwarded missing the part, it all could have been avoided.....So what started out as probably a $5 part for them ended up costing them not only the loss of this engine order but several others which would have followed, in addition to the cost of shipping the engine back....Maybe in the grand scheme of things this means nothing to them however as a customer my dollars are better spent elsewhere..... |

Interesting! It would be great if you could continue here with some pictures as you progress along. I had trouble once, not eBay, with trying to get parts for a friend's commercial mower, same as you, I not learn what people were saying until I already sent the money. PayPal did get our money back, the money many had donated to help the guy. I will post photo's as the scooter progresses. I was notified today that the engine that was returned to the ebay dealer under the ebay buyer protection plan has arrived back in CA at the dealer. It remains to be seen how long it will be before my funds are returned. Hopefully, it won't be too long and I can reorder elsewhere. Only other item I can add is I will also need a replacement throttle cable and will order that at the same time. Since this scooter was designed for battery power, the current cable ends under the floorboard at a mounting bracket. I would guess it probably hooked up to a potentiometer that controlled the electric drive. |

so do you still have the frames , or did you send them back ? John Yes, I still have the scooters....They were a different deal altogether and am really happy with that purchase. They appear to be nice solid units. I only sent the engine back because it was misrepresented in the ebay listing and because their customer service was zilch.... I saw (too late for me) in another section on this board that others have had issues with this company.....wish I had seen that first. It would have saved me a lot of aggravation. Once all is said and done and my funds are refunded I'll order another one elsewhere. I would expect it will be a week or so. Funds will come from the ebay buyer protection plan and not the company. Evidently, ebay will take up the issue with them to recover their funds. |

Does that scoot have a leading link front end on it? I don't know if my terminology is correct but I think this would be called a trailing link suspension. The fork is frontmost anchoring the link pivot. It is followed by the shocks and the front axle is on the end of the link, farthest from the link pivot. Make sense? |

You're right new2scooters, that's a mystery scooter. Looks like a great project though. Is there a VIN number on the frame? Send me that along with your social security and credit card number.  But seriously, if there's a VIN on the frame we can look up which manufacturer made it. Rich No, unfortunately there is no VIN. Because these were "in process" a VIN had not been issued yet but MI has a procedure where I will be able to get a VIN issued for it. It is not too involved, mostly making sure the i's are dotted and the t's are crossed. All materials used in construction must have a documentable paper trail and copies of receipts have to be submitted. I looked into this first prior to sticking my neck out for 4 of these and it looks to be manageable. I've started accumulating parts for the first build. Have a wiring harness, starter relay, reg/rect, fuel tank, etc.... I did have a new engine, however because it was mis-represented as being complete (and wasn't) it is on it's way back. Long story here but thanks to ebay buyer protection program they ruled in my favor and I was issued a return shipping ticket at no cost to me.... (buyer beware of gold3288gold.....) Enough said....Original cost plus original shipping will be refunded.... |
