Suzuki uz50 i have a suzuki uz50 scooter/moped usually when i have the back brake held on i can rev the engine, however recently if the rear wheel isnt turning the engine cuts out, this leads me to have to push the scooter to get it rolling and then the engine slowly rolls into life. any ideas?

Question edited for a lot more clarity.

BTW it isn't a Moped because it doesn't have pedals 'Motorised and Pedal operated - 'mo ped'. It is a Scooter.

Here is your service manual. Check all connectors for corrosion, check fuses and grounds on the lights. It may be a voltage rectifier issue. Probably need a good electrician.

I would be very surprised if a moped scooter had a 'Steering WHEEL'. In my day, they were called 'handlebars', and your part that failed is called the 'steering lock'. It is a generic Chinese scooter, so support is limited. If it is a combined ignition and steering lock, try turning it a full rotation one way or the other. Steering locks are normally a standalone device that is not part of the ignition, but can use the same key.

If you are having difficulty moving your Suzuki Burgman 125cc scooter backwards, there could be several reasons for this, including mechanical issues or problems with the scooter's weight distribution. Here are a few things you can try to diagnose and fix the problem:

1. Check the weight distribution: If the weight is not distributed evenly on the scooter, it can make it difficult to move it backwards. Try adjusting the position of the scooter or shifting your own weight to see if this helps.
2. Check the brakes: If the brakes are engaged or not properly adjusted, it can make it difficult to move the scooter backwards. Check the brake lever and make sure it is released, and try adjusting the brake cables to see if this helps.
3. Check the wheels: If the wheels are not properly aligned or there is damage to the tires, it can also make it difficult to move the scooter backwards. Check the wheels for damage or wear, and have them aligned if necessary.
4. Check the engine and transmission: If there is an issue with the engine or transmission, it can affect the scooter's ability to move backwards. Have a mechanic inspect the engine and transmission to make sure everything is working properly.

If none of these solutions solve the problem, it's possible that there may be a more complex issue with the scooter. In that case, it's best to take it to a certified mechanic for a professional diagnosis and repair.

DO NOT RIDE WITHOUT YOUR BRAKES!
What exactly do you mean by "Pulls up"? Is it slowing down quicker than normal like your towing a heavy weight? Are there any new sounds the scooter is making. Comment below with this information please.
Try this. Do this with the engine OFF and the key OUT. Does your scooter have a centre stand? Set it on the centre stand and get a helper to lean on the rear of the scooter to keep the front wheel off the ground. kneel in front of the scooter and spin the front wheel by hand. It should spin easily. Pull ******* the brake lever and try to turn the front wheel. It should not move. Get your helper to move to the front of the scooter to hold the front wheel down and raise the rear wheel. Use the same method as the front to test the brakes. The rear wheel should turn smoothly with only a small amount of resistance from the engine and transmission and only lock solid when you pull ******* the brake lever.

there are no engines on mobility scooters

i have a uz50 suzuki it turns over but wont spark

I suspect that the electromagnetic brake has seized. I have come across this a few times on some of the larger pride scooters, usually if they have got wet and been left for a while. They can normally be free'd off. First, loosen the left hand rear wheel nut (the one in the middle of the wheel). Put the scooter into freewheel and jack the rear wheels off the ground. Remove the left hand rear wheel and be carefull not to lose the hub key which locates between the axle and hub of the wheel. Unplug the wire that comes out of the brake, then remove the brake from the end of the motor. Before going any further, check to see if you can move the disk inside the brake (the disk is the black part that you can see on the inner side of the brake with the hexagon cut out). If you can move this disk at all, the brake is NOT seized. While at this stage, plug the brake connector wire back in , turn on the scooter and press the throttle lever. If the motor spins, you can discard the motor as being of any promblem. If the brake IS seized, it will need to be dis-assembled. Dis-assembling the brake usually requires the removal of 3 or 4 small allen headed bolts on the rear of the brake, followed by some spacers, small washers and a small ball bearing or two. Watch what comes off and in what order, and be carefull not to lose any parts. Free off the black fibre type disc from the metal plate that it is stuck too. This can be done using a small hammer and large flat bladed screwdriver taking care not to damage the disc. Lightly rub the metal plate with fine grade wet and dry to remove any rust or dirty deposits, then re-assemble the brake in the reverse order, and refit the rear wheel making sure you apply a small amount of grease to the axle shaft.
This should work for you but failing that, I think you will need a new brake assembly.
Hope I have been of some help to you.

Your drive belt snapped. If it is a 50cc, 4 stroke engine, chinese scooter, with a 10 inch rear wheel, then you most likely need a 669-18-30 belt. That is the most popular scooter belt on the planet and is available for about $10-$35, depending on the quality you want. Any scooter shop can change it for you. It only takes about 15 minutes, but expect to pay a chargeable labor rate of .5-1hr since there are unexpected problems occasionally, and there is cleanup time, paperwork time, etc. It should cost about $30-$75 in labor plus parts. Any more than that and you are getting ripped off. You may have other worn parts in your transmission such as roller weights and variator guides. These tend to wear out on chinese bikes around 3000km+. If they are worn, change them while the technician is working on it. It shouldn't cost you any more labor, just the parts, about $12-$20 for the rollers, and $8-$12 for the guides. Cheap belts last about 2000-3000km, good belts last 5000-9000km. Pay the extra few dollars for the better belt, you won't regret it. If your belt broke prior to 2000km, then you may have a defective part in your transmission, such as the rear pulley. That usually comes as a "clutch pack" and generally sells for $40-$90. If you have more than 2000km, it probably snapped just from normal wear and tear. If you can't find a local scooter shop, you can reach us at www.solanocycle.com. We can ship you any parts you need. This repair is not recommended for novices. Although it is easy for those who know how to do it, you can damage your crankshaft and ruin your motor if you do it wrong. Hope this helps.

take it for a full service, clean it, check your brakes r not to tight, check all your oil levels, clean your ait filter ( all done in ur service), check your bettery isnt flat, all that kind of **** n hopefully it will be a smooth runner again
