200s stalls when hot

[PAPA250r]

Having an issue with my 84 200s stalling once its hot it runs great other wize .

Recently put a new rickystator in it and the carb was redone with OEM parts on unrelated issues so its not those


It starts right back up a minuet or two after it stalls i am pretty stumped . Can these things vapor lock ?

PS i tried to run it with out gas cap still does it

Plug fouling? Although it does start back up again, but just a suggestion.

I have seen this problem before when the ignition coil (to the spark plug) was going bad. You can test it yourself, just have a look at the manual, you just need a volt/ohm meter and check the coil OHMs per manual. You can also test the ohms going to the stator coil, just to be sure that one is not faulty.

Hummm thanks I will check the coil when its hot and see what it reads .

[mike84bigred]

I think you can get a new coil for $10 for these things. I would buy a new one anyway.

One thing to watch for.... an ignition coil or a stator may test out as perfectly fine when cold, but will fail when hot. Try to get the bike to warm up until it stalls, THEN test the components. CDI boxes can do this as well, I've pulled a few apart and found the solder that connects the pins to the board have melted. Unfortunatly honda CDI's are epoxy potted and can't be fixed.

Thanks thats good information . I will check it out tuesday Hot and cold lol

If not electronics you may have some floaters in your float bowl that are plugging up your jets and then dropping back down into the bowl after it stalls.

i think you could have a fueling issue. when was the last time you took the carb appart and cleaned it up perfectly clean? if it has been a while, may try that if coil tests ok. when i first got my 200x it did the same thing. i ended yup hacing to over adjsut the idle screw, set the needle to 1 from the top and put in a bigger jet. no more problems and runs like a scalded cat!

The carb was totally rebuilt with oem parts . And it was doing it before i rebuilt the carb

[PAPA250r]

After testing the coil it was good . Turned out to be the new stator from ricky stator the lead where it solders on was loose and melted when it warmed up

I wish they still sold oem source coils all of the aftermarket ones are crap it seems didnt even last 2 months

I had that happen on a ricky stator as well... How i fixed it was to get a crimp terminal, such as a ring terminal, cut the ring portion off so you just have the back sleeve part of it that crimps onto the wire then put that over the wire that goes to the wire from the coil, crimp em together and then solder the buggers. The crimp will add some mechanical strength to the solder joint. That one about drove me to drinking when the owner rolled it off the trailer swearing at it. I finally tore it all apart and found the same thing you did.

My guess, they used regular old rosin core solder, they should have used higher temp silver solder or at least high temp tin alloy to prevent melting.

[PAPA250r]

Thanks but I am not sure this ones fixable . Plastic melted and the piece where you solder to fell off as well

[atc007]

Sounds like nothings changed out there.. Why do companies sell crap?

[kb0nly]

Ahh, it was too far gone then. I got lucky and fixed it, but i haven't talk to the guy in a while, wonder if it kept working... LOL
