Question gas gas txt pro ... no spark ?

the other day i wanted to take the gas gas out for a spin and it refused to start. it was running fine a week ago, now it has no spark.

i changed the plug and made sure that the plug cap was secure.

i've ordered a replacement coil which is a shot in the dark.


ideas ???

always check your kill switch 1st.

That thread has a lot of useful info, but do check your grounding points a the coil or nearby. There are around four grounding wires un der the tank that ground tot he frame, usually in two places. They are assembled dry and will corrode, especially in some environments.

wasn't thinking about it but yes +1 on kill switch and grounding points.

I had the pleasure of being the recipient of the last "no spark" thread and it was the stator causing the problem. You can check yours by unplugging the big plug near the CDI unit and checking between the red and blue wires with an Ohm meter; a good stator will show 16 ohms. Nothing and you've found the problem.

Thanks for the great pointers. Wow 4 grounding points
I'll start looking it over next week.

1fxs- im guessing you meant stator? if it turns out that it is the stator where in the crap do I buy a stator for this thing? (txt pro 250).

Whats the best place to buy gas gas trials parts ? I've never had to buy any parts for it other than grips, tires and pads.

Yes, it should be stator, dumb fingers. I got my stator through Jackscycles, two days and I had parts in hand. Stu is the man!

Question

I checked the grounding points. it looks like they are all connected to the frame with one of the bolts that holds the coil to the frame. they appear to be good to go.

I inspected the connections and wires for damage. no damage and all connections are good to go.

still no spark.

I removed the stator cover today but need the flywheel puller tool to get it off. I have the holder tool.

The gasket is bad. there is corrosion on the flywheel and the ... thingy with the wires coming out of it. could the corrosion be my problem ?

I am going to hold off on replacing the coil (I have a generic coil) until I can get a look at the stator.

I have had no spark from a metal chip between the flywheel and the hall effect sensor, that spark triggering thing on the upper right of your pic. Not sure if iron oxide could do the same because iron is not so conductive once it oxidizes.

That rusty crap is why I like to seal everything with clear lacquer during setup. Water is sealed off from doing that so badly.

Your flywheel is likely pretty stuck on the shaft, being dry and corroded. Soak that area with oil or something like PB Blaster before you try to pull it. When you reassemble it, grease the shaft and flywheel bolt.

it seems like the flywheel puller tool i bought has an inner shaft that is too short.
anyone have a link to the correct tool ?

My flywheel puller has an insert that likes to fall out and roll away..... perhaps yours is missing?

i just ordered one from jacks cycles $40
and the gasket $?

he told me that there is supposed to be a ball bearing insert that comes with most pullers

the unit i purchased off of Amazon didn't have that .
