Check the wiring for shorts. Espicially the wiring for the coil and the cdi. It may be wire shorting onto the frame give the coil a weak signal.

If the bike hasn't run much it won't recharge the battery in a short period of time after extended cranking. Also a shorted wire could be causing a drain.

Yep, once you get it running better, the battery will be fine.

I looked in the manual for my DB-27 Dirt Bike and it says to use this spark plug "D8RTC".

I look at a NGK spark plug conversion website and it says that if you have "D8RTC" plug you should use NGK "DR8EA" plug..

The plug I just pulled out of my bike is a NGK "D8EA".

Is there a big difference? What do you all think?

VinceDrake · 12-09-2008, 06:33 PM

Not at all. DR8EA and D8EA are the same plug. The "R" denotes that it's a resistor type is all. Fits the same, runs the same, same heat range, just the resistor type has ever so slightly higher spark voltage, and less radio noise. If you have no radio on your bike, you've got no problems.

my battery wont charge now.

Its always something. I will have to buy another one I guess. didn't see any loose electrical connections. my new xmoto 250cc chinese dirt bike arrives tommorrow morning. I wont feel free until the db-27 is fixed.

Keep us posted on the xmoto, I plan to order one this spring. I don't think my Lifan would handle too much real offroad, and I plan to ride alot of good trails with the xmoto.

It makes me wonder if the stator is weak also. Without a good stator the bike won't have the power to run the ignition system.

puush · 12-10-2008, 11:54 AM

where is the stator and what does it look like?

Thanks

IronFist · 12-10-2008, 02:17 PM

A clymer and a volt meter might help you. :?

I never want to steer someone to a mechanic, it's not my nature, but a hot mechanic could/might/may have you going in 20 minutes and could be well worth the cash. If you have snow on the ground, you may want to spend the time and learn.

katoranger · 12-10-2008, 02:42 PM

You stator is under the cover above the shifter. It creates the electrical power for the bike. If you get the bike started and idling you may be able to test for voltage from the stator. I still think that you may have a coil/cdi problem.

Here is a pic of a stator.

I have sent the bike to 2 mechanics already. A stock car mechanic and a lawn mower mechanic and they couldn;t fix it. Thats why I am here. I will try battery one more time, then what step should I take next? Coil, CDI, Stator? Thanks for all the help you guys are great.

Cal25 · 12-10-2008, 07:27 PM

You mentioned that you are getting another bike. You may luck out and the coil and/or CDI might be the same as this bike. Try swapping the parts out 1 at a time and see if that fixes it.

There should be some tests you could do with an OHM meter to diagnos the stator but not sure where the info would be.

Be patient and keep trying. Did you replace the spark plug yet?

puush · 12-10-2008, 08:53 PM

i got new spark plug but battery is dead.

katoranger · 12-11-2008, 07:59 AM

This link may be up some help.

There is a good chance that the coil and CDI from you new bike will swap over.

I remember in an earlier thread that you said you had a problem before switching to the new carb also. I am suspecting the Coil or CDI to be the more likely failed part. Neither are expensive.

Hi Michael,
Couple of thoughts:

1: I had a Suzuki QuadSport act similarly. Tried every thing posted here. Didn't find the problem until I pulled the carb and took it totally apart. Sand grains caught in a couple of jet openings. Rough shaped, so some fuel got by, but they were wedged tight enough that they weren't going to move. Air pressure from the motor side to blow the trash out and tooth picks to the rescue on one of the removable jets.

2:I've had problems with the lighting system on my GY-5 and did a lot of checking on the electrical side.
Here's one thing to check to see if the stator is OK for the ignition:
Find the wires running to the CDI from the stator.
One will be "hot" and the other will be the general chassis ground color.
Take the plug out of the bike (so there's no compression).
Set your volt meter to AC and to measure whatever is over 50 volts (mine goes from 30 to 300).
Hook the voltmeter red test connector to the hot CDI wire and the black test conn to the ground wire (or ground to the engine).
Have a friend give it a healthy kick with the kickstarter. (it takes both hands to hold the test wires, unless you have clips to grab the wires

)
(And make sure you don't have a finger touching the metal test probe :twisted: Yeah, found out the hard way

)
I got a reading of 35-45 volts AC on mine and that is plenty to start the bike with the kickstart.
If you have something less, it may be the stator.
If that checks out OK, time to go up to the CDI and/or coil.

It is not necessarily "easy" to change out the stator. On my Lifan 200cc, you have to drain the oil and pull the left side engine cover. 'Bout 10 bolts, gasket sealer and LocTite to button it back up.
Hard to say if the stators will be the same, also. I bought one on Ebay and didn't catch that it was for a GY-6, just the it was a 200cc China engine. When it arrived, totally different from the one in the GY-5.

Gotta love to tinker, if you're gonna ride a China bike :wink:

Later,
Bill
