Hi, Eddie_vine in order to check out any main system electrical circuit, you have to start with a fully charged battery 12.5 volts or better, and be able to pass a load test if necessary.
1. Check battery terminals for damage or corrosion, check 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.
2. Check the voltage drop at the battery when you hit the starter button, anything below 9 volts you might have a faulty battery.
3. Check voltage at the battery with the bike running at 3,600 RPM should be 14.3 to 14.7 volts. If you are not getting these numbers, you might have a faulty voltage regulator.
4. Make sure voltage regulator is grounded and functioning properly, watch the video below on how to test a voltage regulator.
5. Unplug the connector to the alternator and hook your multimeter leads to the alternator (pin/socket selection does not matter) set the multimeter to AC volts, at an idle the meter should read 16 to 20 volts AC. at 2,000 RPM 32 to 40 AC volts, 3,000 RPM 48 to 60 AC volts. If you are not getting these numbers, you may have a faulty rotor, follow step 6
6. Set the multimeter to OHM'S, connect one lead to the alternator (any pin/socket) and the other to a ground, the meter should read infinity. Connect both leads to the alternator meter should read 0.1 to 0.2 OHM'S. If you are not getting these numbers, you have a bad stator.
7. Check all wiring in the charging circuit for worn or chaffed spots and all wiring connectors in the circuit for corroded, broken, or loose pins/sockets, which is the # 1 offender.

sounds very much to me as the cylinder is shot, they do repair kits but i personally would change it you cant take risks with brakes.

2004 Derbi Senda... | Answered on Sep 06, 2011


Sounds like your chain is stretched and not fitting the sprocket properly or is just too loose. Check your front and rear chain sprockets for wear and ensure the teeth are straight. Check to insure the chain fits snuggly on the rear sprocket. As a chain stretches over its life, it won't fit in all of the teeth on the rear sprocket. This will cause the chain to ride up on the teeth at higher RPMs and jump (causing the feeling of a jolt or **** as it grabs again). Typically, the chain should have no more than an inch or so of play when properly adjusted.

The fuse box should be very near the battery. Start there. Next check the wires where they plug together at the tail light. Next look for loose or dirty connections. Now look for any abraded wires. Next look at the key switch, is power getting through the switch? You do have good light bulbs don't you? If your bike has a headlight, often multiple circuit connections are inside the headlight housing.

If the bike has knobby type (bumpy tread) they do make noise.Just be sure they have the correct air pressure in them.
Try to support the bike so you can manually spin the wheels like if the bike had a center stand.Feel while turning, to see if the wheels feel to tight or loose.And try to feel any play in the wheels. Or hear any stange noise.
While your are at it go ahead a drain the oil and change it with a good quality oil. The bike should have come with a book to tell you what type oil it wants.Dont be afraid to change the oil more than it is suppost to be.They dont hold that much oil and the shifting of the gears will generate alot of break in metal dust that needs to come out of the engine.
To say if you made a mistake in buying the bike remains to be seen because their is no history of the Chinese bikes in this country.
If I could ride the bike I could give you a better opinion.
Another thing you could do is, while riding the bike with it makeing the sound,pull in the clutch and put it in neutral.Is the feeling gone?
This can help to be sure the noise is not engine generated.

2004 Derbi Senda... | Answered on Dec 03, 2009


Two other things to try. Make sure the battery terminal connectors are absolutely free of buildup. Then place your battery on a long slow charge. If it is not sealed, checkto make sure plates are all well covered with distilled water.

Finally, hook the battery charger up to the battery and move the selector up to start, say 50 amps. Try that. If you still have nothing but clicks, and all bolts and nuts are tight, time to look at the starter itself.

2004 Derbi Senda... | Answered on Sep 23, 2009


I understand that Honda's have this problem when they warm up. Try slowing down a bit more before shifting into first.Also, ensure you are kicking it all the way down past neutral. If the problem occurs from a standstill, try rocking the bike back and forth in neutral as that sometimes does the trick.

1. Severely discharged or a damaged battery, 9 volts or lower.
