6 months.. 250r still down :(

[cbennett86250r]

Good Compression.. no spark :(
brand new cdi
brand new coil
used stator..

the bike ran for a little while.. like 5 minutes.. then died, as if you hit the kill switch.. no spark again..

stator gone bad?

someone said something about bad grounds.. but they look ok to me..

i duno

I had almost the same problem that you did, my 250r would run for about 10 minutes and then just shutdown, I bought a new cdi, coil, and cleaned the carb and was still doing the same thing, I bought a new wiring harness system from service honda and that got rid of my problem. They didnt have one for 86-87 so I bought 88-89 wiring and it worked fine. If you havent replaced the wiring harness I would try that.

Good Luck,

[cbennett86250r]

thanks.. i'll try that..

I bought this 250r for $2500.. was it worth it?

i have pictures at home..

just makes me wonder if i got ripped or not

[EastCoast330]

No problem, Dont feel to bad, I bought mine for $3000 and still had to drop another $1500 to even get mine ridable. I got screwed by someone that I thought would sell me a good quad or even one that just ran halfway good. Once you get the R dialed in you will like it, has tons of power. Let me know if you have anymore questions I might be able to help and they also got some guys on here that really know alot about the R.

Good Luck,

Electrical problems will drive a guy nuts! If you get a new wiring harness, for a $125.00 you can have a new stator too and your whole electrical system will be new. Keep your old stator for spare.

CHECK THE KILL SWITCH WIRING, I'VE HAD A PROBLEM LIKE THAT ON MY DIRT BIKE

[wilkin250r]

Have you gone through the electrical diagnostics in the repair manual?

[XCredrider]

i dont know if this could be your problem since you said it ran for a minute but i couldnt get spark with mine because the pick for the stator was too far away. It had gotten bent somehow when it was apart and it wouldnt get spark. I just pushed it till it was close or looked good and it got spark and started right up.
:cool:

[JTRtrx250r]

I always start at the kill switch, and work my way from there. It could be anything tho

after you get it hammered out... it'll definitly be worth it!

Good Luck w/ it

[cbennett86250r]

it ran for awhile.. before all of this happened.. first it was the cdi.. then we just kept finding more things wrong..

i dont know if the cdi quit? and then shorted everything else out?
i really dont know..

but i love the bike..
i have friends with yfz450s, polaris predators, 400ex's and 450rs..
and im new to the sport..

but the 250r is just more fun..

rav it up real high, dump the clutch, ride a wheelie off the line.. and leave em sittin..

hill climbs are great too.. just lean over the bars and keep it pinned..

lol.. i would love to get it going again..

[wilkin250r]

I can't imagine the CDI causing other problems. Knowing how the electronics work, it's just really unlikely. It's very possible the CDI could go bad, but it's very rare for it to cause OTHER problems elsewhere in the system.

Again, have you taken a multi-meter and checked the specs according to the manual?

[cbennett86250r]

no i havent done much diagnostics myself.. i have a guy here locally working on it at the moment...
he says hes going to look at it again tonight.

[200386250r]

I had this problem on my 86. It was the spark plug cap and wire. On the 86 the spark plug cap was touching the spark plug wire just enough to start but than it would cut off..Make sure your plug wire and plug cap are tight and that they have good contact with each other.

I had this same problem with my '86. You may want to check this. Your best bet is to do as Wilkin suggests and go through the electrical diagnostics in the repair manual. I believe in the Honda manual in gives you a range of resistance readings to check between certain points in the quads electical system. The meter used to check resistance is fairly inexpensive and available at most hardware stores. I was always able to isolate my electical problems by doing this. Good Luck!

[cbennett86250r]

well some friends of mine worked on it all night last night.. have decided it is the stator :(

they say its possible that the flywheel could be holding on to moisture.. from the tranny fluid getting in there..

so i need a new stator.. *sigh*

was thinkin about going ahead and getting the lightened flywheel too..

also.. where can i get a 86 wiring harness.. i hear you cant get them anymore.. you have to get the 88-89..

and if i do get the 88-89.. what will i have to change?

Thanks!

[wilkin250r]

How did they determine it's the stator?

[EastCoast330]

If you buy a 88-89 wiring harness you dont have to change anything, It will mount up to the 86-87 with no problems, at least it did for mine.

[JTRtrx250r]

89 is diffrent, the plug is diffrent. I'd order an 88 unless you plan on buying the whole 89 gig

They sell it 88-89 or 86-87, I dont think you can buy them in certain dates, they dont show them on service honda as certain year:confused:

[cbennett86250r]

which plug is different?
the cdi?

[JTRtrx250r]

here's 1 thread I could find, theres others, this 1 came up 1st..

If you are replacing the stator, flywheel, and wiring harness it may be worthwhile to look at upgrading to the CR ignition available from ESR? Just a thought.

I don't have direct experience, but I do have the repair manual and wiring diagram sitting right in front of me. From the wiring diagram, it looks like there are two differences.

First, the 88 wiring harness has wires for the key switch, but that's no big deal. The "on" position is an open connection, so you can just leave them disconneted. Wrap some tape around the ends of those to protect them, and leave them alone.

It also looks like the exciter coil and lighting coil have seperate plugs on the 86, but they are combined into one plug on the 89. This isn't the end of the world, because you can just snip the wires and twist the connections together and bypass the plugs completely. I recommend heat-shrink tubing, to keep water out, if you go with this method.

Can anybody confirm if I'm accurate?

[beerock]

im with wilkin, how did they determine it was the stator? the stator.
you need to check all the electrical with a meter,

check the alternator stator, Standard : 50-250 ohm
(86-88 disconnect the black/red wire check the resistance from the blak/red wire to the ground)
(89 disconnect 2piece connector and check the resistance to the ground)

check the pulse generator, Standard: 50-200 ohm
(disconnect the pulse gen and check the resistance with the blue/yellow and green/white


check the alternator stator lighting coil, Standard: 0.1-1.0
(86-88 disconnect the white/yellow wire from the stator
89 disconnect 2piece connector, check resistance between white/yellow and ground)

Replace any of these components if they do not measure in specifications

there will be a sticky on all this shortly

88 and 89 are two different wire harnesses. The stator connectors are different. You want to get an 88 wire harness to go on a 86. The 89 will not work unless you change the stator as well.

[cbennett86250r]

i think it meters ok.. but i think when it gets hot.. or under any stress.. it quits.. what else could it be?
