hi you……I have a used Yamaha Neos (bj 1999) for about 6 months now since 4 weeks I have big start difficulties. He hardly jumps on with e-starter still with Kickstarter. Sometimes he jumps on, but goes out after 3 seconds again. And sometimes…very rarely he jumps at once….udn if he runs then also really good…..often even when I have pushed half the way to home. ….mediumly because 3 people have allegedly know with it n the whole thing was taken apart … air filter and carburetor taken apart and tested … battery, spark plug and suction plug is new..but it didn’t do anything …..has someone an idea what it could be …I think I’m going to the workshop with it but I’m afraid that they’re doing something new that doesn’t have to be..because I have little money at the moment…….I’m a little desperate now because I really need the roler …and I also have experience at chiao or so read that have a lot of start problems with the neos….is that maybe a problem that this model brings with it? Please answer quickly…

Hello, I am completely new here and hope that my contribution is right here. I recently added a Kreidler Florett City 50 4T as a craft project. Since I was interested in learning from screwing, little to no idea, I searched through forums and various videos. I added the scooter with a conrod bearing damage and broken valve, ergo also smashed piston. Have the engine ( GY6 139QMA/QMB ) completely apart All engine seals were also renewed. New cylinder, new cylinder head (but with shorter valves than before) new control chain, new control chain rail, new camshaft. Everything in 50ccm. In principle everything was completely renewed inside the engine. I also installed a new CDI and new alternator because I noticed that the old two cable blanks were sharpened. Now to the problem: The scooter jumps sup If I let the scooter turn on the main stand everything works, as soon as the rear wheel touches the ground it does not come from the spot. I give gas but it does not start by itself. If I push it with my feet and give it gas, it slowly accelerates but I come to 30Km/h at the highest and then it ends. For me it feels like the engine is really going to speed but the power is lost somewhere. Has possibly j request a tip for me where the problem might lie? LG

Hello together, I am at a point where I don’t know what to do. I don’t want to throw away the scooter either. I have a Piaggio Sfera 50 NSL. Some time ago there were problems with the electrics whereupon I changed the alternator. After about 50 km driving with new alternator (and without any problems) he started to stutter etc. Having arrived at home I noticed that fan wheel (which sits on the alternator) has fallen off. I didn’t really like this. This is how I don’t get the car running anymore. Mega starts off badly and when it goes out quickly again. I asked at different places and everyone gives you a different tip, so I tried and renewed the following things. Air filter cleaned and new left battery new spark plugs new carburetor new shaft sealer on alternator side new with and without exhaust started cylinder, piston new suction nozzles new bis z My hope was that with my new cylinders (compression with the old 5,0 ) something was going on. But here the compression is minimally better. Should I change the alternator again? (With light etc. I have no problems anymore) So slowly the money runs out.

hello, I plan with a few friends an approx. 1000km tour on scooters. since some have only the B license, we wanted to limit ourselves to what you can drive. most will probably try with 50 ccm construction market /ebay classifieds scooters. we have some mountain stages and I have a mottorrad license. therefore my question, I can burn an 80 cc scooter per scrib at 45-50km/h so that I can have more power at mountain, but am not faster than the others? ch should it go, do you have to register something like that? as a marginal note, we are all Ü30, have already played out and want to be 100% street legal on the road

Hello, I have the following problem… My Sym Allo, 50ccm, 4 clocks, which I bought as a hobby vehicle, does not start at all. The problem was that he has no suit and always came only weak up to 30kmh and then finally drains. Now he no longer starts at all. The spark plug is wet after every start attempt and in the suction nozzle it is also wet. I spark is there. Compression is with 11 bar I think, valves are also set. I tried with small but the problem also occurs with the 40s (smallest size). Original nozzle is an 82s. After this did not work I bought a complete new carburettor. Also unchanged. I have slowly the feeling that the ignition spark is not enough to ignite. Does not ignite even with starting aid. I am really at the end of my knowledge and please for a few tips. Thanks already

Hello, I recently bought a MBK Nitro, it ran wonderfully. after a few kilometers it went out, then I got a new cylinder with piston and everything around it (the old had already 38019 km down) now I drove about 15 km with it, also nice gently because it is new. suddenly he went out again. then I screwed out the ignition candle and looked if it is wet, so whether sprite comes – candle wa dry. afterwards I then got the nozzles out built and cleaned…sprit arrived now still not. today I bought all three nozzles new and built in – candle is also wet again, nen funken has se also aba start he still does not want to. so I made candle out, dry with lighter and I once torpedoed the scooter with full gas without candle… candle back in, aba it just doesn’t do anything I hope you can help me.
