SOURCE: cant get my 50cc scooter to fire up-no spark. any

  • Do you see spark? If not, check the side stand kill switch. It kills the engine so that you don’t start out with the side stand down. If broken or out of adjustment, it would kill the spark. Check for a broken wire at the side stand switch and coupler. Try moving the side stand kill switch by hand. If that doesn’t work then wire a jumper around the switch to bypass it.
  • Is the handlebar kill switch on? Is it shorted out?
  • Check the fuses.
  • Check the operation of the ignition switch and all kill switches with a volt ohmmeter. Check the wiring harness. Did a wire come unplugged? Are all wires clean and with solid connections? Any abraded or pinched wires?
  • Is the bike in neutral and the neutral light is lit up? If no neutral light, check the neutral switch and neutral switch wire on center or side casing.
  • If still no spark, get CDI system and coils checked at the dealers shop.

Unless you find a small "restricting washer" between the head and the exhaust pipe...Then usually there is no easy means. In the past these "washers" were put in place to reduce performance, the idea was as the riders skills improve the washer can be removed. It also was a way for parents to keep their children from zooming flat out everywhere.

SOURCE: Znen Scooter Headlight keeps burning out!!!!

sounds like you have too much voltage coming out from your battery, mabey a faulty regulator. The easiest way to test this, is to get a multi - meter, and check the volage output at the battery, with the engine running, at idle should read about 12.5 - 13 volts. Then rev the bike up, and seeif the reading changes, it should not go more than 13.8 or 14 volts max. If it does, then i say you have a faulty regulator/ rectifier.

SOURCE: how to or can i

first major restrictor is in the exhaust pipe. Take off all the securing nuts and bolts to remove the pipe. You will notice in the end of the pipe that fits to the cylinder head there will be a washer that reduces the bore of the pipe. You will need to grind away the weld that secures this washer, clean out all metal particles and refit pipe to bike. This will dramatically improve the performance. Hope this helps' Alex.

I need manual for 2010 ZNEN 125 T-F scooter.Please any information. Thank you


Hi, Miguel the vast majority of service, parts fiche, and owners manuals on the internet are "FREE" to download and all service manuals contain wiring diagrams in the back pages. The rest usually charge a modest fee around $10 and there is a handful of obscure, rare, obsolete, and very old models that are no longer or never were available, for these rare occasions I shall look on eBay and find the cheapest one available. Most of the manuals will cover your exact make, model, and year otherwise one will be provided that comes as close as possible to your bike and will have most of the same info that an exact manual would have. If there is no $ sign after the manual link it is free to download for viewing or printing. To download your manual please click on the blue links below. Good luck and have a wonderful day

I've got a 50cc scooter does 40 top end Good on acceleration I've put a new plug lead and 6.5 rollers in it and a new belt, but in between acceleration and top end its slow any ideas?


Hi, Nathan it's only 50cc what do you expect? and how do you know it's slow? have you raced any other same make and model and lost? for this situation, I would call my local dealer or reputable shop's service/parts department and inquire about any possible quick fix, answers, or parts inquiry.

Hi, Mitchell and the usual suspects are:

2. Damaged or restricted fuel tank venting system.
3. Inlet system air leak.
4. Vacuum piston malfunction.

6. Plugged bowl vent.
7. Fuel level in bowl too low.
8. Restricted fuel supply passages.
