Evening, would have a question because I have no idea about scooters at all. Large car engines can withstand about 200-500tkm depending on the maintenance. How much km does such a 50cm3 engine last? Whether 2- or 4-stroke is really not important, but I prefer 4-strokes. Oh, one more question. What do you need on 100km? Greeting Ercan

Hello guys, we want to take part again this year with our DT 50 in a 4h moped race. The rules say unfortunately from that we have to drive with 50 ccm. Has from you good tips like we the Zyl. best beabeiten can increase control times, channels etc. and which carburetor and exhaust combination best fits to it. We have a Gianelli and an empty org. DT50M exhaust. As a throttle we have a 19er Dellorto and a 20er Mikuni. Zyl. we have a n older and a newer Dt Zyl. It would be great of you to get some tips on the matter. I’ve already looked through a few topics in the forum but unfortunately they are partly a bit older and the links don’t work meh

As already described above, I wrongly refueled my Aprilia Rs 125 today. I always refueled the V-power of Shell. Unfortunately, I got out of my way today and filled V-Power Diesel. Although I noticed the error after 3 l. Diesel and then poured 8 l. of the usual….But now to my questions because I am quite unsuspecting. Can I drive this filling without any problems? Should I suck off the tank contents? I may have already broken something because I am not sure about it. At home I also experimented a little bit in the stand…. I am grateful for “almost” every answer. ByeZz

Hello people, I am 16 years old and I am very interested in cars and bikes! Have a 50ger Motocross and the M-Schein myself. Because I am very interested in the topic of cars and bikes as I said, I wanted to ask you if you have interesting links, books or references for me where I can make myself smart like these vehicles work. So the individual components!!! Would I be very happy if you would know! Will absolutely learn like a car and/or bikes (especially re Mopeds) work! Thanks already once in advance! Your cartmaster

Hello, I would like to know which drivers, whether they are to blame or not, are involved in most of the accidents mentioned above. I think the 125 drivers are often at fault (by too high speed and wrong assessment of their own abilities) as e.g. the Mofa and 50 drivers (to whom cih is still a member) who are often involved in accidents by wrong overtaking of cars. I feel like I have at least 4 times a week so tough by a Karr I’d like to know if a 125er isn’t safer, because they don’t get overtaken so often. I’m mainly interested in data and facts. Would be great if you could help me. I’m sure it’s interesting for others as well.

so I don’t know I have them already 300 km with low speed 1:50 in the tank in addition not for two, no mountains etc. drove in and plötzzlich while driving jammt the thing me häds almost laid uung the track of the matures is about 10m long (I was so at70km/h as described in the drive-in pan turn up short distances, which so far always went well) and now that, meanwhile it runs again, and to the happy as before, but the running area has already got something and I’m afraid that this will happen to me again on the right road (was just heating up the road) so I hope one of you knows what I can do to avoid that.

I now want to buy a 50cc machine, first I was fixed on the NSR 50 from Honda because I was too expensive the RS from Aprilia. But now I noticed that a lot of people drive the DT from Yamaha, what advantages does this box have. Which 50s should I buy, whether athletes, enduro or cross. The price should not be all too high, so no luxury machines. I used to buy them. What did you do for experiences with different boxes? Since I really at the moment no ch have no idea which are good now etc. I would be really grateful if you could help me.

HELP!!! I have bolted my Yamaha together today and already have the first problem. I don’t know which main nozzle I should screw in my 24 Mikuni carburetor or how I should adjust the mixture. Although I already use a large HD (how big I don’t know because I drilled it) and have set the mixture as fat as possible I can hear a ring from the cylinder. From the assembly instructions I can see that a Kling I don’t want to skyrocket another cylinder!!! Please help me as quickly as possible! That’s what I’m talking about, above all, those from the forum who also have a polini cylinder. Which HD should I use? Do I have to attach 2T oil to the gasoline during the drive-in phase? Is this kinging or knocking even when the setting is optimal? Is that even normal with the polini? Or do I have something to do with the installation wrong done? How did you adjust your carburetor? Is it normal for the piston to cause slight scratches? I will disassemble the cylinder tomorrow and take a look at the piston. I hope that until then many answers have accumulated in this topic. Thank you in advance. MfG mXs-Freak

Hello guys, I have a little problem with my DT50R BJ. 93. 70ccm Polini, Sport-Krümmer, serial exhaust In the 5th course the part does not really get to speed. I have to turn up in the 4th course up to over 65km/h, which also goes without any problems. When I turn into the 5th course it tortures itself a little bit. 70km/h I still manage, but then also no long ground wave can come. I notice the “rise” then, although it is very flat on the Lower Rhine. The tempo falls then rapidly and I have to enter the 4th course. All other gears can easily be turned up…… My thoughts were the following: throttled CDI: but then why can the other gears be turned out? Carburettor set incorrectly: but why can the other gears be turned out then? Air filter is cleaned. The machine has already run faster (so 80 on ́m Tacho) As a candle I use a NGK BR8HS. Original is a BR7HS at 50ccm. However, the original Yamaha roller (sorry) of my r girlfriend also a BR8HS ??????? Does anyone have a reasonable idea what I could try out here? Oh so, one should also mention that I am 1.90m long (CW value from a fridge) and so bring about 130kg on the scales (my little DT moans there). I wonder that here everyone is looking for a 6th course. With me a 6th course would be as useful as a wooden leg for ́n divers !!!!!! Greetings Schmal66

Servus Vorgeschichte: I broke the cylinder head gasket on Monday, Moped squirted out of the exhaust until it goes no more and power was also no longer there. So I completely resealed my cylinder head, renewed gear oil and cooling water and tried to kick on. Except for a few banger out of the exhaust did not do anything. With pulled choke it jumped 1 times for 1-2 seconds but then immediately died off. So I removed and cleaned the carburettor, My question is now if I have to recalibrate the ignition time, since I currently have a 2mm cylinder spacer in it because of my 44mm stroke Kw. And if so how do you do it with an Ori ignition, have read something about a ignition wedge, he should put the ZZP in front of it but where exactly does the part go. Please for a quick answer.
