250R, getting spark?

[risccas]

as I mentioned before....I just aquired a 1982 250R. It was missing the coil and plug wire. The previous owner told me that the CDI was bad and that all it should need to run. I replaced the spark plug and went thru the the carb while waiting for the plug wire, coil, and CDI to arrive. Those parts have now arrived and I just installed them. So then came the moment of truth. I kicked it about 50 times, and it never came close to starting. I'm not sure if it's getting spark. Here is what I observed though. If I have the throttle wide open when I kick it, it sounds much different than when it 's closed. It's louder, more of a rumble sound to it. Does that mean I'm getting spark or you can just hear the motor better w/ the carb opened?

Does that make sense?

yeah but the sound differences don't mean anything... take the spark plug out and put it in the plug boot and hold it to the ground and kick it over, you should see a spark

[risccas]

OK, I just tried that and it looks like I'm getting no spark.

There are some things to check for good spark. Stator, correct wireing, cdi, coil, kill switch. One of these things one by one should be able to detect the problem. I know the manual for this bike should give you specs to check the circuts with a meter to see if they are good. Otherwise take them one by one to a mechanic and ask him to check them with a meter. Ask someone on here and I am sure they will help you find a PDF manual for your bike. Good luck.

OK, here's a quick question before I assume it's a bad stator. I had the stator cover completely off the bike when trying to start it. That would not prevent it from getting spark some how would it???

the cover wont affect anything

[Bryan Raffa]

no that would have nothing to do with it not getting spark...

[risccas]

OK, well that really sucks! Dont suppose anybody here has a stator for a 1982 250R that they would sell real cheap.....???

if you had the stator off then no it wont fire. put it on and check it again. isnt the stator mounted on the cover on these trikes? the stator and flywheel could be rust covered not letting it fire.

[risccas]

The stator was on, the stator cover was off. Yes there was quite a bit of rust on the flywheel and stator. That could prevent fire? Is there a way to clean it w/o taking off the flywheel? Any details would be great!!!

Yes the rust on your stator can prevent fire. You need to pull the stator out and clean the coils and the contacts out. But if there in really bad shape you may consider replacing it.

You will need a fly wheel puller the get the fly off too, don't pry it or you will F it up.

I am wondering if there was fix for this? I too have no spark.

I replaced the source coil (bought from Ricky Stator) as I wasn't getting any voltage or very little (less than a volt) while kicking it over. I also replaced the spark plug coil just since I was in there. I get about 6 volts while kicking it over. That doesn't seem to be enough? Is it? Anyways, still no spark. I even ran a separate ground wire from the coil mounting bolt to the engine case.

Anything else I can try?

I thought the source coil powered the coil and the other coil under the flywheel was for the lights.

Help me, I've fallen and I can't get up.

Just start a new thread this one is OLD:lol:
I dunno you have tried already what i would have

Ha ha, yes it's old but it is also a thread that was never resolved. Would be great to get a fix, so this thread can be useful to others that use search. :D

I would first make SURE you're not getting spark. It's hard for me to hold the plug on a bare spot on the jug with one hand, and kick it over at the same time. Have someone hold the plug on a good ground while you kick it hard.

If you're not getting spark, then it is SO MUCH EASIER to have some known good parts to swap.
These are the things you need to maintain for a good spark on a two stroke:

Coil (make sure the contacts are rust and corrosion free)
Stator assembly (Check the connectors for mud, rust, corrosion etc. and clean the stator mounting area)
Spark plug wire and boot (unscrew the boot and make sure it's not corroded.)
Switch. (The switch can corrode and lose contact. frustrating)
Spark plug (Do your testing with a new plug)
CDI ( usually when they die, they die. Get one or two from ebay...you may need it if you plan to keep the trike for any amount of time)

In my experience, testing these components via multimeter etc. does not work. Having known good parts on hand that can be swapped is the easiest and least frustrating.
I have a spare coil and CDI you can use for testing purposes but need them back. :)

Thanks for the lengthy reply.

Here is what is brand new:

Source Coil
Spark Plug
Spark Plug Coil with attached wire and boot

The switch when off gives no voltage, with it on gives 6 volts. I am assuming this is functionable but good tip on cleaning it.

CDI is stock but I didn't know this controls spark, so I may buy a spare to try.

Thanks for the offer.

Can you see if your getting the same voltage on the wire connected to your coil and ground off frame/engine? If so, let me know what voltage your getting. That would be a great start.

[MPDano]

Pulled the CDI off and took it inside to look at it and the numbers. Decided to back back outside and look at the connector, it looked really corroded. Shot some De-Oxit on the plug terminals and will see if this helps overnight. Will try it again tomorrow after work.

I got spark. Still no start. Got only 60psi on compression check. I think this is my issue. Gonna start a new thread on compression.
