ATC 70 up and dies after i installed new points

[42F67N]

I bought new points and a condensor the other day for the atc 70 cause the bike started to run rough and i had allready filed the points down once.

so i installed the new points and condensor took the bike out for like 10 mins and rode it and it ran awesome had lots of power.

so after that i took my kid out on it we only got like 5 mins from my house and the bike died,so i brought it home and checked it for spark it has none so i went back into the points and checked um all out to make sure i didnt like forget to tighten something or anything like that and everything is fine i know the wires didnt come loose because on the atc 70 u have to solder them on.

what do u think happened to make the bike have no spark?

has the contact got burnt spots on them. some times you can get oil, even oil from your hands and cause them to burn up. check and make sure your gap is still correct. also i havd found if you buy cheap points they always screw up. then again your problem might be elsewere.

[42F67N]

The contacts look perfect and i cleaned everything up after the install and then again after it stopped running,i bought the points from beatrice atc and they said there oem points for the bike so i dunno bike has me stumped

[thehickfarmer]

did you change the stator ???

[Macs]

check and make sure your gap has not changed. then check and see if you are getting power to the points. sometimes you can see a small spark when you pull it over if the pints are actually getting fire.

[42F67N]

I didnt change that stator and thats what i was curious about if the bike was running on the orginal points since it was new and me now adding new points that are firing perfect could it burn the stator up?

[thehickfarmer]

yes i belive it can.. i am not 100% sure but i heard it happening,check your stator

[42F67N]

soon as i get this bike running 100% perfect somthing else goes poop :mad:

[thehickfarmer]

hey man i know how u feel, my buddy restored a 86 250, it looks like new, fired it up, 10 minutes later the top end blows up, he forgot 2 put a head gasket..

[42F67N]

i was checking prices on beatrice atc its like 90 bucks + shipping for a new stator and 50 + shipping for a new coil im debating fix it or sell it lol

How are testing spark? Spark plug to ground or a spark tester? If you are using a spark plug to ground method it is possible you have a bad spark plug. Let us know what method your using to identify the problem.

[Macs]

stick a screw driver in the plug hole and hold to about an 1/8" from ground if you are getting a spark it is your plug. if not then it is somewhere else. now installing new points shouldnt burn up your stator. usaully when it does it is on atv with a battery and the ignition is left on.

check Ebay for cheaper prices on the stator and coil. ;)

[42F67N]

I have a light that goes between the plug and the coil wire i checked it like that with a new plug i also checked it by holding a small screwdriver in the coil wire to see if i got a shock and nothing :(

Afew pulls and check the plug and it ahs fuel on it so its not a fuel problem

[plkmonster2]

Check for loose wiring, or grounding wires. This seemed to happen a lot to my old 110. The wires were old, and got loose and eventually just popped apart.

I tested the bike tonight in the garage with the lights out and the points arent even sparking :confused: gotta be a problem in the stator i think lol

[kdagenais]

I would find it hard to believe your stator or coil went bad (but it is possible). My suspect would be the wire came unsoldered or got damaged by the flywheel if it wasn't routed correctly. I would pull the flywheel off again to check the wire to be 100% sure before you start buying unnecessary parts. The coil and stator can be tested with an Ohm meter but I don't have the details to tell you how on the 70. If you have a manual it will tell you how to test them and deem a bad part before you waste your money.
Good Luck and keep us posted.

I would agree, and also suggest disconnecting the kill switch to eliminate it as a suspect.

I'm going to try to rewire the points and condensor if that dont work i will put the old points back in and see if it starts,i do have the manuel so if i do the above and it still dont work ill figure out how to check the stator since the points arent firing i pretty much figure the problem isnt the coil

I rebuilt the kill switch like 3 monthes ago when i got the bike because it was really sloppy so i dont think it could be the kill switch.

I have just about every part brand new on this atc with the exception of the stator and the coil and a ton of money invested lol so if ihave to i guess ill spring for a new stator to lol

I was looking at this guys auction on ebay he sells a 50cc motor thats complete with the carb coil and everything u need plus its a cdi engine for 300 bucks only downside is its a 2 speed and i dont think it would be very peppy with the 50cc motor

Plkmonster2...my 110 lost spark, and I am wondering if you could tell me what parts of the system were troublesome? I rode it to the end of my alley, and it just dies...no spark(holding the plug against the motor). It has an '85 110 kill switch and headlight, if that helps. All ideas welcome. thanx

Try a new spark plug is where I would start.

[hondatrikesrule22]

I had trouble with fouling plugs...so when it wouldn't start that was the first thing I changed....

[42F67N]

I believe it was the new condensor because i changed it and the bike ran fine
