Question about Yamaha G5 Motorcycles

1 Answer

I recently changed the drive belt on my 50cc roketa scooter and had trouble with the clutch staying engaged, that part is fixed. Now it will idle ok, but when I throttle up it doesn't have enough power to pull itself.

The belt has to be the exact correct width or the clutch will not function properly. Too thin and it will rev too high and run slow. Too wide and you wont be able to pull off. The same with a belt that is too long.

    i also bought an apache quad bike from apache quad.com (Quads direct) they decided to replace my bike but it devoloped faults when i tried to contact them again they said they had closed their atv department so my 2year warrenty was useless. I have trading standards involved. But in the meantime i contacted the manufacturers in tiawan(access motor company) who were very helpful and sent me the parts i needed. My advice would be to tell trading standards and then ask your local bike dealer to contact access motor company in tiawan. Gud luck!!!

Hi, Jerry 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.
7. Vacuum hose to the fuel supply valve/petcock disconnected, broken, cracked, or pinched.
8. Fuel valve/petcock or filter clogged.
9. Fuel line to carburetor or throttle body pinched, kinked or blocked.
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, Msmcenaney before testing any electrical component in the Starting Circuit 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. Ignition Switch not in the "ON" position.
2. Engine Run Switch in the "OFF" position.
3. Check the 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.
4. Bank angle sensor needs a reset or is faulty.
5. FOB battery low or dead.
6. Faulty ignition switch.
7. Faulty starter button.
8. Faulty kickstand, clutch, neutral safety switch.
9. Security alarm needs a reset.
10. Starter relay, solenoid, starter motor or circuit wiring faulty.
11. Starter armature or field coils have failed.
12. Main fuse or circuit breaker may be blown or faulty.
13. Faulty ignition relay.
14. The electric starter is working but starter clutch has failed.
15. Check for engine trouble codes.

I was driving my 50CC scooter down the road today when suddenly i lost power. after stopping i started the scooter again, turned the handle to go and nothing happens. the engine sounds fine and revs up,...


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.
