Fantic 300 No Spark

Featured Replies

Hi everybody,

My name is Bernie and i'm from Holland.

Last week i've purchased my '84 Fantic 300 Pro

(the Michaud replica)

Last monday i fired it up at the previous owner and

it worked allright.

This week i serviced the bike (did nothing to the electrical)

and today i tried to fire it up; no result.

The problem is; i don't get any spark!

The bobine is an Mitsuba 3390 from Italy.

Does anybody know what the problem could be?

Just out of interest....did you wash / pressure wash it?????

That's just it.....i did'nt touch it with a drip of water.

Just put a new chain on it, cleaned out the brakes and put

a new mikuni on it.

I'm going to collect a new Ducati coil tommorow (fits on many

scooter bikes) and try it....

The fitted coil is wrong...all Michauds had Ducati coild. The colour marking from the stator matches with those shown on a ducati coil. let us know how you get on.

Fitted the Ducati coil; changed red to green and green to red; one little spark........that's it!

Turned the cables back to their normal colour code; nothing.

Then changed the colors back to oposite;....one little spark.

The funny thing is; past monday it started well at the guy i bought it from, took it back to Holland,

changed and serviced some things (did NOT touched any of the electrics)and it won't start again.

I think i'm going slightly mad.....

The problem is; i don't have the tools to take the flywheel off. Otherwise i could look at te inside...

eehhh.....any suggestions?....somebody??

The old adage, "what was the last thing you did " would be a good starting point.

Sorted by time:

Monday: purchased the bike; it ran without problems

The next few days;

- changed the carb en inletrubbers

- changed the airfilter

- changed the handlebars (the kill switch isn't connected)

- changed the chainset

Thats it!

I even thought about the electrics

The only thing; on transport to holland the bike fell on its right side in de truck

and after transportation i haven't started it yet.......

could something be broken near the flywheel???

Change the plug, if you still think you have no spark, hold the plug and kick it over.

If your hair stands on end or your heart stops you've got power.

Is the plug wet when you try kicking it over ?

I try to get a spark with the plug out of the head.

I just hold it against the head to see if it gives a spark.

Put the original carb back on and try starting it with that. Maybe the new Mikuni is not jetted correctly for the Fantic.

Hi John,

It's not a carb problem; it's an electrical problem; i don't get any spark

No spark; no ignition; no fun.....:-(

Hi mates!

A miracle just happened!

I'm not a quitter so i went back into the garage and tried the old and the new

coil....no result.

For the last time put back the old coil, connected everything and then.......sparks sparks.....lots of sparks!!!

What made the change?.....i really don't know...honestly...i really don't know....

But it works....

And the new Mikuni tm26 worked immediatly....just a little adjusting..that's all.

Only have to look for a small seat because mine has an larger seat.

Thank you all for the inputs and thinking!!!!

Cheers, Bernie

(ps: sorry for my english writing...)

Hi Bernie ; Just a few thoughts ...

1.Bike needs ducati coil ...

2. Kill switch lead is there somewhere shorting your ignnition ...??##%%???

3. Bike is about 30 years old ! pull off the sidecover and flywheel , buy some quality wire in the correct colors and get your soldering iron and heatshrink tubing out and rewire the ignition !!! So ypu know it's right , a dead bike on the trail is a pia for all involved !!!:) (and a poor connection or a broken wire that you may never find could be the whole problem .)

4. ENJOY the heck out of the bike and learn all about her ! THEY ARE FANTASTIC BIKES !!!

Have Fun !

Glenn
