Hello together, I have received a scooter from an acquaintance for my 15-gen son. Unfortunately it turns out that it is only a 25 km/h scooter. Now I want to open this at our village workshop at 50 km/h. KfZ Meister has already agreed with TÜV that it is no problem if a new CDI is installed, but it requires papers from the same scooter that is already registered as 45 km/h to extract some data (gas values etc.). I have been uploaded in the appendix. Does anyone here in the group have an idea where I can get these documents, or does one of them have such a scooter and can provide me with a copy of the admission? Thank you in advance. Greeting S.Selich

I have a question, and that is: My scooter didn’t jump, following it was removed from me by a buddy of the carburetors, where the water was seen in the carburetor. Unfortunately, the seal was not carefully removed from the float chamber, but pulled out. Then he cut off a piece of the seal, so it fit again and put it in. The scooter was then assembled, still did not jump on. In the carburetor water had been, how much I know unfortunately Icht. Then he screwed this airscrew half to the right, so that it gets fatter. Then he jumped on. What he now unfortunately has, at 30 he goes down briefly, but pulls immediately again. Unfortunately he now only drives 40 on the straight, 45 down the mountain. But one day BEFORE it was like that he drove 50 on straight and mountain down 55 around. It is a Kymco Super 8 2 timer built in 2017 740 kilometers on it. Then turned again at the airscrew to the left, then wur He pulls off well at the beginning, but at 20 it is already like walking away from the gas very briefly, minimally as if he lost power. Then he goes up to 35, after that it is again like walking away from the gas for a short time. That looks like he wanted, but he can’t open before the carburetor he drove great, 50 on the straight, 55 mountain down. The wheel turns only minimally when he runs, at the beginning he turns high until he just starts to jump on he does sup he. He also pulls well at the beginning. Do you know what that can be? Does he hang it together with this float chamber seal which was cut and re-installed? Am I desperate, since he drove still smoothly the day before ?? The seal was practically emptied from the float chamber from pulling and did not fit in any more, therefore he shortened it. I ordered a new seal.

Hello, it runs easily on the stand, pulls up nicely. When driving, however, no full throttle is possible, it doesn’t pull, just tuckers comfortably in front of it, just before drinking. After I cleaned the main nozzle it ran about 200 – 300 m, then no more. I already tried another carburetor of the same type, it’s just like that. Does anyone have a solution proposal ? Thanks mfG

Good evening, I took out my SYM JetX 50 Sport after about 1 year in the garage and wanted to get it ready for the road. I filled in new liquids, cleaned the carburetor, cleaned the tank. I wanted to start it now, but it doesn’t start. Even with start pilot, no chance. Not with e-start and not with kick-start.. I measured compression, only has 5 bar. What can I do now? What do I have to/should I check everything? What else can it be? that he doesn’t want to start. Ps. Zündfunke I checked and is available. Thanks already for tips and information.

My scooter, a Kymco Super 8 4T, was still running perfectly before the holiday. After the ten days of vacation he jumped directly as before. I started, and everything was normal, until it suddenly jerked short, because the scooter briefly took no gas. Finally, he took no gas at all and went out. After I had tried it for a long time, he jumped briefly, but ran only a short time before the same problem occurred. It seemed as if he was trying to jump off again and again. he then didn’t run anymore. When the scooter had stood for a while, I tried again, and he jumped on again, but quickly went out again. I looked at the spark plug that I had re-set. It was black, so I cleaned it, and the scooter ran a bit further, similar to the first ride after the holiday. I then tried it with a new spark plug and the air intake valve on the carburetor turned out a little bit, but the role However, r didn’t jump any more. So it can’t be the spark plug. The old spark plug still worked and the new one also worked. I really don’t know what the problem could be, so I ask if someone has an idea because of my description. I’m surprised that the problem occurred after the somewhat longer service life, since the scooter was running perfectly before.

I hope someone can help me further is desperate and I’m running out of ideas. I have a Rivero VR50 2T 50ccm built in 2010. The scooter does not get petrol it does not build up a vacuum on the carburettor. I have replaced the gasoline pump, gasoline filter, Simmerring cylinders & pistons, intake nozzle new air filter ect. Between intake nozzles and membrane I have lubricated silicone seal that can withstand high temperatures quite easily. All 4 light when I blow pure and are also all tight. When I suck at the vacuum hose petrol comes but if I try it by E starter/kick starter nothing does. The compression is very good. Echoke tested on the battery the needle moves. With brake cleaner in the carburettor then the scooter jumps immediately and then goes out again.

Hello together, I need your expertise The petrol no longer reaches the carburetor. Unfortunately I don’t know if there should be petrol in the hoses or not. I have solved all the hoses on the petrol pump. In the picture I noted in which hoses is petrol and where not. Is that so correct or can the error be there already? Roller no longer starts and when I spray “motor start” into the air filter it starts briefly smoothly. Therefore I assume that it is a I hope you can help me. Thank you very much! LG Criss

Hi guys, I’m looking for an NMAX and wanted to ask you if I should get the model by 2020 or rather the newer model. Is there any big difference in your experience what the reliability or quality is all about? The extras of the new models like Start/Stop and ASR etc. are not so important to me. I’m more concerned with the quality and reliability….has something changed there? For example, I read in a review Is it different or better with the new model? Are both models equally fast from the suit and the final speed? Is the suspension and the driving comfort similar? Can you put other tires on it if yes which improve the driving comfort much more? What scares me a little bit at the new are the things the S tart/Stop and ASR the more extras the more can get broken or make problems. Can you make this model even though it is a 4 clock a little faster by other Vario rolls or sports exhaust or other ? Please also here accurate information and tips. What must I pay attention to when buying except the usual things that you see and hear so visually….? Please share your experiences with good as bad….and please give me lots of tips ! Thank you first…

Hello dear forum, I’m completely perplexed, so here’s my first entry at all in a forum: The problems have started so that the scooter suddenly went out while giving gas instead of speeding up. I’ve been doing a lot of things since. The symptoms have changed, suddenly he took gas, but only up to 10-15 km/h. If I give more gas, he wants to go out. Why could I avoid the problem by putting on the rear brake LIGHT. That’s of course not the problem solution and doesn’t work any more anyway, but maybe someone knows what it might have to do with it. For me that makes absolutely no sense. So far I have done and checked the following: -Air filter completely cleaned and checked for leaks. -Carburettor completely new (I also tried to make carburettor settings, however, no difference) -Benzine filter fetched -Benzine supply checked -Underpressure checked -CDI checked -Ansa ugstutzen checked (looked pretty good, but I still think I’ll get a new one to see if that changes and I really don’t have any idea what else it might be) -new spark plug hoses checked for leaks – cabling checked The scooter always jumped in normal (speed changed in the stand gas, which is why I actually started out of wrong air).Currently: scooter no longer starts sovereign, only on ach and krach and gas he takes a I really hope that this forum entry can help me.

Good day to the community here. I would like to introduce myself briefly. I am new here in the forum, I own two 50cc scooters (Aprilia SR 50 AC and a REX RS 450), and I don’t like to “demotivate” but now I can’t really go on. My REX 450 has been mucking for a long time, (starts badly, bad gas adoption) so I thought, after all these years a new cylinder kit comes on it. (50cc standard) Penible according to Naraku instructions I then have the 101st Octane cylinder kit + Naraku head without SLS. I changed with: – new carburettor with 85/35 nozzle – new insulator with O-ring – air filter incl. box – valves set (0.10/0.10) no mechanic blockings ect. he also jumped on, ran him 2x 15 min., when giving gas some black smoke came out of the exhaust. Well, I thought because I had oiled the treads of the cylinder before I thought about it again. Engine stopped waiting for 1 hour each The next day I wanted to go into detail with the carburetor. Now the scooter doesn’t start any more. Spark plug looked at, black and damp. I don’t know any more … The only thing I noticed when checking the components that the insulator doesn’t match 100% with the hole opening of the inlet on the head. Since I used the old standing bolts I can exchange them again, but whether that’s the reason ??? without sucking the hand laid before the inlet while kicking, this sucks very neatly. I need help from the professionals please !!! Did I miss something ? THANK YOU 🙁
