I have a 1999 hyosung SD50 sense. Now, I've done a lot of research and there's not much out there about this model but some people say its a morini style engine and others say that it's a minarelli style engine and I have no idea, but I'm hoping that some of you, might. I want to upgrade my scoot to a 70cc big bore kit but don't know which kit if any will fit. I'm posting a link to some microfiches for my scoot, the first is for the engine cases the second is for the cylinder and the last two and the tranny. if anybody could help me identify what style engine it is that go a long way also here's the engine stamp SD50-147456 1: www.alpha-sports.com/hyosung_parts.htm 2: www.alpha-sports.com/hyosung_parts.htm 3: www.alpha-sports.com/hyosung_parts.htm 4: www.alpha-sports.com/hyosung_parts.htm your help is greatly appreciated. |

CHINESE ENGINE CODE DECIPHERING Hey MO! How do I know what engine I have? I have heard all this talk about 1PE40QMB and 157QMJ blah blah. It seems so darn confusing to get parts for these Chinese bikes! What can you do to help? -Lost in Las Vegas. Chinese bikes and ATV's can really be confusing, that is why scrappy dogs was started. There are two identifications to remember by using this site for help, not only to know what you have, but to get what you need. The first is the engine type. While this site uses a simplified directory at the left, you really need to know the engine number to get your parts right. This engine number is typically in two parts on the same stamp location. Most of the time the numbers are stamped on the left side of the engine, under the belt cover, near the front close to the engine mount to the frame. The bottom number is the reg. number, the top number is the one to pay attention to, this is the engine identification number. It tells you what you have. Below is a picture of a number plate for a 50cc 4stroke, also known as a 139QMB. The engine number is very significant, and reveals alot. Take for example a popular engine, like the Honda Monkey (chinese copy) The number stamped on it is a 1P39FMB. The first number is the number of cylinders, the second, a P, is code for a horizontal engine. The next 2 numbers, 39, is the bore diameter in mm, 39mm bore. The next letter, F, indicates that it is natural (not forced) air-cooled style. The next letter designates that it is a motorcycle engine "M". The next letter reveals the full engine displacement. B is code for a 50. C for a 60, D for a 70, F for a 90, G for a 100, H for a 110, I for a 125, J for a 150, and so forth. Notice that the size graduation increase is indicated by an increment in the alphabetical letter? It's no coincidence. It's amazing to me the cooperation in standards of China. There is also prefix letters on many, designating the manufacturer, like Quinjiang (we have them all on file), which stamps there acronym, QJ, as the first two letters in there code. It's also very revealing, as the QJ139qmb is quite different then the other 139qmb's. It uses the 1E40qmb (2T) transmission components, and the engine case is a little different. There are also suffix numbers at the end, which designate iteration levels, like -3 in the photo below, which denotes that it is the third design, or improvment. Call or email us if you have any questions. We love to help. Here is the Chinese engine code chart with the example of the JOG 2stroke engine number 1PE40QMB-4 Some engines have the number plate on the upper rear side of the belt cover. GY6 engines are on the fron, bottom, left had side near the centerstand pivot. 2stroke JOG's are near the rear wheel like Honda Spree elite and DIO. They are often on a sticker on the belt case. Sometime the airbox needs to be removed and alot of grime washed off on the 2strokes. By federal law they are stamped on the engine case and are there, even if you don't see it at first inspection. Either way it will help you significantly to know this. As far as the chassis body parts go, you can reference your body appearance to the listing shown in the Chassis directory given at the left, or simply click here- www.scrappydogscooters.com/CHASSIS_PARTS.htmlThis list is growing weekly, so if you don't see your bike here, check later, or better yet use the Parts Finder form on the home page. Scrappy dogs are committed to making the Chinese vehicle market easy and fun for everyone, and affordable too! Thanks for the question, hope your not so lost anymore. MO! |

i guess a better question would be what makes you think that? I'd like to know for future reference, I'm still going to try to find the engine stamp tho, just because I've heard it both ways supposedly hyosung didn't switch to morini until 2006 but thats why I started this thread.

After scouring my scoot for the elusive stamp I realized that its Korean and most likely doesn't conform the Chinese standards anyway.
