Points arcing despite everything Question Help!

Ive had the same magnum project thingy for over a year and half. Its had a number of kits on it, it was previously not sealed right, and now it is....

Just a regular case matched e50 to a metrakit, 3 shoe and perf crank, nothing crazy, 19mm carb setup.

Any who...

Since ive had this bike , its backfired with any kit ive put on it. One i soft siezed racing a kymco scooter ( yep im an idiot ) And another ive since moved to another bike. Now its got its 3rd kit on it and it still backfires.

The one thing i keep coming back too is that the points arc. Always have.

I replaced the condensor and point last year, still arc'd.

Rode it around all last year, but at wot or high rpm's every once and a while it would backfire. GO figure.

So this year, i replace the points and the condensor again, use those really nice NOS points and a nice new condensor, and they still freaking arc. So someone sensibly says try replacing the coil. So i do. Still arcing points

So today after losing my mind , i run up , grab a new stator, and a whole new condensor , and flywheel, and put the condensor in the stator, move the new points from yesterday over, and put the whole new stator over to the bike and put the new flywheel on.

The arc a lot less , but you can still see the odd spark now and then between the points!

I rode it and could not get it to backfire a wot, but it was boggy...

I realized the only thing left i havent tried is the damned spark plug wire - it looks good but , hey its all ive got left i havent tried.

I have tried advancing/retrarding and all sorts of gaps on the points.

?

Re: Points arcing despite everything Question Hel

this is like seeing your own father get punched int he face or something. ive never known andrewhed to get beaten up by a moped problem like this before. its kind of frightening. . .

your problem is the points. Put on some cdi.

I'd also check all your other wiring, make sure there are no shorts, and really good, solid grounds (use the motor). I always had problems like this but now I don't with cdi. Too many variables with points for a likely crummy return

Re: Points arcing despite everything Question Hel

HAHAHA

this is just freaking me out. I mean im out of parts to replace lol.

the scary thing is Jay...the spark plug wire cap is a moby one.

Whats the chance it IS the wire cause it was once on a 50v and cracked moving with the variation of a moby?

Re: Points arcing despite everything Question Hel

naw, i have a cdi right here in front of me and im finishing this battle mano on mano, points and condensor style.

those treats CDI's are for quitters.

Actually they are for my other motor LOL so ill not be doing this again, but im gonna figure this out of if it takes all year.

Re: Points arcing despite everything Question Hel

This started happening to me about a month ago. I was running stock points system from 1980 on my bullet. After adjusting and actually changing the point itself, I took the stator/ignition coil from a 1994 A35 and slapped it on. It ran really really nice for a solid week then started doing the exact same thing again just not nearly as often. I was still crazy fast but it didn't feel safe. One of these days I will just switch to a CDI system. Friend of mine is starting to have the same problem on his ped, and he is cdi so I can't really explain that shit.

Re: Points arcing despite everything Question Hel

Im not putting a cdi on it because i cannot figure out points LOL

Re: Points arcing despite everything Question Hel

your points are always going to arc, theres nothing you can do about it.

set your stator to stock location, set points to stock location, get a brand new condensor.

Wire it up properly. Make sure the wires are connected to where they should go. Ground it properly.

Get a coil that you know works and put it on and ground it correctly.

get a new spark plug cap(2 dollars) and wire ($2?).

and get a new ngk spark plug with the right heat rating.

its not that hard, come on, your probably missing something really silly.

Re: Points arcing despite everything Question Hel

arch is a mystery and is rarely solved.

Re: Points arcing despite everything Question Hel

points are always going to arc put if you have a spark plug wire or a plug cap or a ground that has to much resistance or a bad low voltage coil can make you have a ton of spark on the points

clean and sand all your grounds

chang cap and wire

chang low voltage coil

Re: Points arcing despite everything Question Hel

all my grounds are totally 100 percent. like i said, condensor is brand new.

cuperblasto, if you read the post you would see ive done all that shit. Im not a half wit honestly. Ive never had any wierd prob with a puch, never even seen one do anything funky at all electrical wise.

as of today the points are new , the condensor is new, the coil is new. Gotta be the plug wire. Its all thats left.

Re: Points arcing despite everything Question Hel

the reason this is frustrating cuperblasto is , well, ive logically gone through and done everything you siad, makes total sense. And your right , its probably something silly, but it not what you and I wrote.

And no, the points should NOT be arcing out if nothings fucked up.

Re: Points arcing despite everything Question Hel

and like i said , its probably the spark plug wire.

Re: Points arcing despite everything Question Hel

Run it in the pitch black dark.

If you see a slight blue glow like an aura, you are getting spark scatter and replace your High-tension wire, or if bad, the coil case is cracked and swap out another.

Used to do it on the big-blocks and my Jeep back in the day.

That's when I knew to replace the coil and the wires.

Pitch Black. Seriously. If you find an auto repair book from the 70's, it is in there.

If it is humid or after a rain, you will see more of the blue aura.

Spark-scatter.

Re: Points arcing despite everything Question Hel

spark plug wires do not really go bad. Just the connections.

if it is all proper then it should work.

The points are always going to arc.

Re: Points arcing despite everything Question Hel

dude!

if it is backfiring your timing is way off.

lets see of a pic of your stator!!!

Re: Points arcing despite everything Question Hel

hahaha

spark plug wires dont go bad lol ...

I see you have never had a moby!

They do, especially when they are 30 years old or if someone pirated it from a moby, and it moved back and forth with the variation of the motor.

As the plug wires get older and make more resistance, it causes the points to arc - this used to happen all the time with our cars that had points.

Your right thought, it is the timing.

But here's the gig - the arcing pints are causing the timing to predetonate, thats how it works - thats why you always suspect a condensor when you move your stator and nothing happens.

Here's whats been replaced -

points

condensor

coil

light coil

ignition coil

flywheel

stator

spark plug obvioiusly.

The spark plug wire says "novi" on it.

Im betting its a wire gone wild

Re: Points arcing despite everything Question Hel

Maybe i should have prefaced this by saying ( no im not a "master mechanic" ) that im not a dumass and i remember the days when if our cars died we used to get out, pop the distributor cap and use a fingernail file to clean the points and get back on the road.

I also remember dwell meters and all that fun stuff on cars, figureing out the vaccum advance ( and on some of the wierd foriegn suff we would work on, the centrifical advance)

This is one of those wierd things thats all, just wondering if anyone had any other ideas.

Re: Points arcing despite everything Question Hel

backfiring is only caused by a condensor going bad or really bad timing,.

Re: Points arcing despite everything Question Hel

no thats not neccasarily right, backfiring can be caused by hot spots, or other factors no ONLY a condensor and really bad timing.

but in this case its the timing.

I dont think you get that im trying to agree with you. If the plug wire of something else causes too much resistance, the pints arc , and that TOTALLY screws up the timing.

Re: Points arcing despite everything Question Hel

sorry that was supposed to read NOT only a condensor, and the POINTS not the PINTS lol

Re: Points arcing despite everything Question Hel

points always arc and wires do not make the timing off.

Re: Points arcing despite everything Question Hel

ok, can we agree not to agree?

Re: Points arcing despite everything Question Hel

your wrong.

Re: Points arcing despite everything Question Hel

ok can we agree that im wrong?

Re: Points arcing despite everything Question Hel

i dont mean arcing like a tiny bit i mean like fireworks, then jumping off the bottom of the points and zapping to the ignition coil and shit, like crazy wrong. The only thing left is the plug wire. Its not impossible to think it might be that.

Re: Points arcing despite everything Question Hel

arn't you supposed to see a small spark between the points? is arching when it sparks to some thing else?

Re: Points arcing despite everything Question Hel

a little tiny flicker every now and then is kinda normal. Constant jumping between the points that you can see with the flywheel cover off in the bright sun is not. Thats what ive got going on,

Re: Points arcing despite everything Question Hel

Unwanted sparks on the points can be eliminated (at least what I think so) by installing DIODE in the system.

The benefits of it are multiple.

As stated by Briansolex (big RESPECT to him):

"An additional benefit is that electrical wear of the Contact Breaker is reduced significantly."

I know it's a Solex article, but the principle of magneto ignition is everywhere the same.
