RAPPY 660 wont start on it's own, only on push/tow, HELP!!!

Hello all,

Thank you for taking the time to try and help a fellow rider. I bought a nice new 700R, which is awesome. But am having trouble with my 660.

Heres the thing, 2 trips ago it started not starting in the morning. I had to tow start it, once warmed up afte bout 15 mins and all, u can turn it off and it will start up on its own okay. but if you let it sit it will need a tow again. has been doing this still ever since. Tow start it and it runs great, real fast, just like normal.

I tried a new spark plug, and then did a test and found it is getting no spark at all. Battery is great, The starter seems good, cranks the engine over great, like brand new. Carbs and fuel line are all good and clean (like i said it runs great, once started).

I am thinking it is an ignition problem. If anyone can help all comments are appreciated. I am thinking of replacing the ignition wires first, then the ignition. But am waiting for some help from ya'll first. Thank you much!

Jon

Check the battery first. Especially if it's the stock battery. Take it to Advanced Auto, or Autozone.

My stock battery wouldn't hold a charge worth sh!t, and I ended up with an Everlast from WalMart. Haven't had to popstart, or jumpstart my Raptor since.

Thanks for the post, yes the battey is fine (as stated in my initial post).

I am finding some info and thinking could it be the generator (stator)?

It is not getting a spark

Unplug the rectifier/regulator and try again. If the quad starts, your stator is bad.

never commit yourself to just one option..

have you checked the valve clearance?

improperly adjusted valves will make it not want to start!

other spark options could be the CDI, coil, key or bar switches... etc

No mods in a long time, it has been running great, once started it runs great. FASST as always. But stop it and it wont start on its own. I pulled it apart and tested the plug = NO SPARK.

so 1st onmy list now is to find out how to get a spark again. It started doing this on the first glamis trip of this past season, but I have ridden it in summer and it was fine, then stored for 2 months, and does this now.

unplug your rectifier if you have spark then its your stator.

From his first post, the question here is what will allow it to start (and get spark) by towing it, and subsequently when it warms up, but NOT when it's cold. Any ideas?

Sometimes when a stator goes its not all at once. I had one go out that took a while before it totally quit working. It could be a multitude of things. CDI, Stator, Coil, Coil wire, wiring. All I can think of right now.

Agreed but always eliminate the easy stuff first, it only takes a few seconds to unplug the rectifier and hit the starter button.

ya it is either your stator is bad or your battery voltage drops to low to fire the cdi while cranking so check both of those

how do you know the battery is fine? have you tested it? like doing a starter volt drop test? if not dont say it is fine, the battery can roll over the engine with good speed but be to low to fire the cdi.

Back to basic questions.

When towed, does it start immediately, or require a long time (say more than 5 seconds of turning over)?

You get no spark, you said, when you try to start cold with battery, correct? Have you attempted to start with a jump from a higher capacity (car) battery in parallel with the quad's battery also?

Will it pull start at a low speed, or do you need to get the RPM's up for it to fire?

Trying to put together a troubleshooting scenario that matches what you've described so far.

Quadmaniac:

Tow starting: it starts right away, once it is goin at a fair speed, i can just push start it down my driveway in 1st gear, it gets goin fine then.

The battery is good, it is new, and I did a voltage test on a charger frist thing when this started happening. I am going to try it hooked up on jumper cables tomorrow, just for shits and giggles, u never know.

on tow start it starts up the second you let the clutch out, and then it wheelies! haha

Thanks for the input, let me know what you think

Thanks quadmaniac

Check and write down the voltages measured at the following places when you are cranking the starter, with the negative meter lead attached to the negative battery terminal (not the screw or cable connector) and the positive lead attached to:

1 - The positive battery terminal (not the screw or connector)

2 - The positive battery connector

3 - The negative battery connector

4 - both sides of the starter solenoid / relay

5 - 6 - Both sides of the fuse (only one is active, the other is spare)

Then repeat the same measurements using somewhere on the FRAME as the grounding point for the negative meter lead. (7-12)

This may be just a start. I believe that somewhere in your electrical system you may have a high resistance connection, causing a voltage drop when cranking the starter, with enough of a drop to prevent the CDI from operating properly.

BTW, do these measurement with the battery alone, no charger attached , and only crank for a several seconds for each measurement.

Also, a quick check... when you crank the starter over in neutral, does the neutral light stay bright or dim significantly? I'm gonna guess it dims a lot.

Good luck!
