Hi, Allen there are few things you need to look at when trying to troubleshoot your scooter for power loss. How does it sound? If you run it wide open throttle when warmed up, does it peak out? or stutter? is it loud, or very quite the symptoms can help decide what to try. When you are going full throttle, the engine should get to a high RPM and sound smooth here are a few things you should look for:
1. Plugging air intake- will start well cold, but be hard to warm up and not reach top speed. The engine will stutter at high RPM.
2. Open air intake- to much air or air cleaner is disconnected- engine will not have power at high speed, make vacuum cleaner sound. Acts like it's running out of gas. ( sounds almost the same as a dirty carburetor.)
3. Plugged exhaust port the engine sounds and runs good, but has no power. Slow to take off. Same as plugged muffler, but if the muffler is plugged you get a very smooth exhaust note at idle. Humming instead of pop pop pop pop.
4. Fouled spark plug- backfire. If you get backfire, pretty good chance the plug is fouled.
5. On models with belts, the gear ratio drops as the belt gets thinner (most Honda's have belts).
6. On a moped with high mileage, the belt will cause slow top end speed if worn thin.
7. If you have a bike with chain drive in an oil bath and you "OVERFILL" the oil amount in the chaincase, that makes for slow running as it requires too much power to turn the oil.
8. If your engine does not rev up well and stutters or sputters, like when it is cold with the choke on, the engine is running too rich. (too much fuel).
9. Is the air filter soaked with oil? Clean with soap and water!
10. Is the air opening in the airbox plugged? Very common for a spider or mud wasp to build a nest in one of the intake holes.
11. On some scooters it is common to get a leaf stuck in the intake port of the airbox, causing a 10mph drop in top speed.
12. Don't try to adjust the screws on the side of the carb to get lean or rich, as they are for the idle circuit only.
13. The idle air screw should be about 1 1/2 turns out on most scooters.
14. Say your engine revs but kind of wheezes or acts like it runs out of gas it is common to have a buildup of hard carbon on the inside diameter of the hole in the main and pilot jets, and it must be carefully removed.
15. If your moped does not idle the pilot jet is likely plugged.
16. Anytime a moped has not been used for 1 year or more, and still has the same fuel in it, good chance you will need to clean the jets.
17. The poor quality of today's gasoline has made this a rather steady bet.
18. Mopeds are affected more than most vehicles because the small size hole the jet requires is easily plugged, even by thick oily fuel, or water.
19. Drain your carb once in awhile! Most have a screw of some type at the bottom (where the drain needs to be) of the carb.
20. Make sure the air boot to the airbox is not on wrong, kinked, hard and shrunken.
21. Don't oil the air filter if you got the stutters.
22. On some scooters, you can leave one snap loose on the airbox lid to allow it to crack open, to get full rpm.
23. "WARNING" too much lean out on the gas, and since the fuel cools the piston, the piston can "MELT"
24. Still slow? Check the muffler tip. Make sure no carbon buildup is inside the tip, stick something in as far as it will go.
25. Common on some scooters to have the tip bent over on a curb, then carbon up solid. common of all types to have the whole muffler plug.
26. When you have the muffler off, is it heavy?
27. Can you get the baffle out to see if the holes are plugged?
28. Check the exhaust port on the cylinder.
29. If you can't see all the way into the piston, use a mirror and a flashlight to make sure the piston is ok and the port is not plugged where it meets the piston.
30. Common on all models to plug here, Just scrape it out so the hole is full size again.
31. Don't worry about the small film on the inside of the port, I am talking about a very thin film that forms a wall in the exhaust port right next to the piston.
32. A 1 1/2 inch hole can be reduced to the size of a pea...... With a thin film of carbon.
33. If you can see the piston ok, it's not the problem.
34. If you are in doubt regarding your exhaust pipe being plugged, put your hand behind the muffler to see how much pressure is expelled. compare to another bike.
35. It should blow pretty good and have a distinct pop pop pop pop sound while idling, not a steady humming.

dirty carburetor is my guess. Also check the air filter and that the air filter box is not blocked. Many years ago I rode a 500cc Kawasaki H1 Triple. I drove to the Isle of Man TT to watch the races. The bike was really sluggish and needed a lot of throttle. I was working on the bike at a campsite and a guy pointed out that a sponge I had taken to clean the bike, I had stored it in a gap between the seat and the tank. It was the air filter intake! :>D

Hi, Theresa loved your novella very quaint, 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 of $15 and there is a handful of obscure, rare, obsolete, and very old models that are no longer or never were available and some were never printed in English. The Indian and Philippine markets are usually in E-book format only, 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.

Hi, Cinn "probably" anyways the answer to this question is way above my pay grade for this situation, I would call or visit my local dealer or reputable shop's service/parts department and inquire about any possible quick fix, answers, or parts inquiry.
Good luck and have a wonderful day.

If the old belt was shredded the pieces go into the clutch, and keeps it from releasing, you need to take it apart and clean it out.

Hi, Warryn before testing any electrical component in the Charging System it is "IMPERATIVE" that you have a fully charged battery of 12.5 volts or more and be able to pass a proper "LOAD" test if necessary, you may have a preliminary reading of 12.5 volts or more but little or zero amperage, the battery is faulty and must be replaced. AGM type batteries fall into this scenario more so than lead-acid batteries.
1. Battery Test:
The battery needs to be a fully charged and load tested to ensure proper readings, connections need to be clean and tight. If you are not working with a fully charged and functional battery, all other voltage tests will be incorrect. Standing battery Voltage should be 12.5-13.2 DCV.
2. Charging System Voltage Test:
Start motorcycle, measure DC volts across the battery terminals you should have a reading of approximately 13.2-15 DC Volts.
3. Connections and wires:
Inspect the regulator stator plug, and check the battery terminals for connection corrosion. If everything seems to be in order, move on to number 4 below to determine if there's a failed component.
4. Stator Checks/Rotor Check: Each of the following tests isolates the Stator & Rotor. If AC output and resistance test fail and stator test passes then the rotor is at fault (Pull Primary covers and inspect rotor for damage).
5. AC Output Check:
Unplug the regulator plug from the stator start motorcycle and change Voltmeter to AC volts. Probe both stator wires with your meter lead. The motorcycle should be putting out approximately 18-20 ACV per 1,000 rpm. Reading will vary depending on system, check service manual specification
Generic Specs:
22 amp system produces about 19-26 VAC per 1,000 rpm
32 amp system produces about 16-20 VAC per 1,000 rpm
45 amp system produces about 19-26 VAC per 1,000 rpm
Stator Resistance Check:
Switch your multimeter to Ohm x 1 scale. Probe each stator wires with meter leads and check resistance on the meter.
Resistance should be in the range of 0.1-0.5 Ohms. Reading will vary depending on the system, check the service manual for specifications.
Generic Specs:
22 amp system produces about 0.2 to 0.4 ohms
32 amp system produces about 0.1 to 0.2 ohms
45 amp system produces about 0.1 to 0.2 ohms
5. Stator Ground Check:
Switch your multimeter to Ohm x 1 scale.
Probe each stator wire with your positive lead on the multimeter and the negative to ground.
There should be no continuity to ground on either wire.
If there is continuity your stator is shorted to ground and must be replaced.
6. Regulator Test:
Each of the following tests isolates the regulator only, so if any of these tests fail, the regulator is at fault.
Identifying Wires:
Battery Charge Lead- Wire going from the regulator to battery positive.
AC output leads- Wires coming from the Stator to the regulator.
Ground- Wire from Regulator to ground or regulator may be grounded via the physical bolting to chassis.
Regulator Ground Test: Ensure the regulator body is grounded or grounding wire is fastened tightly to a good ground (you should verify this by checking continuity from the regulator body to chassis ground).
Fwd/Reverse Bias Test/Diode Test:
This check is testing the Diode function to ensure it is regulating the AC current for the stator into DC Current.
Switch multimeter to Diode Scale.
Place your Multimeter positive lead on each AC output wire.
Place your multimeter negative lead on the battery Charge wire.
The meter should read voltage typically around .5 volts.
Next, switch your multimeter leads putting the negative lead on the AC output wires and the Positive lead on the Battery Charge Wire. The reading should be Infinite. With your meter on the same setting, place your multimeter positive lead on the regulator ground wire or to the regulator directly, and then place your meter negative lead on the AC output leads.
The meter should read voltage typically around .5 volts.
Next, switch your multimeter leads putting the negative lead on the regulator ground and the Positive lead on the AC output wires. The reading should be Infinite.
Note: Below is a table to show the readings:
Positive Lead Negative Lead Reading
AC output 1 Battery charge lead Voltage
AC output 2 Battery Charge Lead Voltage
Battery charge lead AC output 1 ?
Battery charge lead AC output 2 ?
Ground AC output 1 Voltage
Ground AC output 2 Voltage
AC output 1 Ground ?
AC output 2 Ground ?

Hi, Koos and the usual suspects are:
1. Fuel tank empty.
2. The fuel tank has old dead gas.
3. Fuel tank bottom contaminated with ethanol sludge, dirt, water, rust, etc.
4. Fuel supply valve/petcock turned off.
5. Fouled spark plugs.
6. Engine flooded as a result of overuse of the enrichner.

10. Carburetor float stuck.
11. Fuel injectors clogged.
12. Fuel injectors stuck open.
13. Severely discharged or a damaged battery should have 12.5 volts or more and be able to pass a proper "LOAD" test if necessary, you may have a cursory reading of 12.5 volts or more but little or zero amperage the battery is faulty and must be replaced, AGM batteries fail in this scenario more so than lead acid batteries.
14. Check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
15. Loose or corroded wire connection at the coil or plug between ignition sensor and ECM module.
16. Spark plug cables in bad condition and shorting check for spark leakage in the dark, cable connections loose, or connected to the wrong cylinders.
17. Ignition timing incorrect due to a faulty ignition coil, ignition module or MAP, CMP, CKP, O2, TPS, ETP, IAC sensors.
18. Faulty neutral, clutch lever, or kickstand safety switch.
19. Faulty fuel pump or fuse or relay.
20. A stuck bent or burnt valve.
21. Tilt sensor needs a reset.
22. Security system not disarming alarm needs a reset.
23. Check for engine trouble codes.

Hi, Vpgold76 if your headlight is not working, only one beam works, keeps burning out, blinking, dim or surges from bright to dim to bright the first thing you need to check is the headlight bulb for damaged filaments then check your light circuit fuse, then check your head light bulb socket ground wire for a clean tight connection, that being said the usual suspects are:
1. Faulty ground or power supply wire to headlight bulb socket.
2. Worn down solder contacts or loose fit of the bulb base in the socket due to vibration.
3. Worn, chaffed, or broken wires in the light circuit.
4. Corroded, broken, or loose pins/sockets in wire connectors.
5. Faulty hi/lo beam switch.
6. Faulty ignition switch.
7. Fuse is good but no continuity on both sides.
8. Faulty headlight relay.
9. Faulty wiring between battery positive and headlight bulb socket.
10. Weak charging alternator/generator/lighting coil.
11. Faulty voltage regulator/rectifier ground or overcharging.
