Fitted this flywheel/stator/rectifier charging circuit for an Ignitec push and go ignition system.

Ran OK for a few minutes then the voltage dropped to 5-6V. Left it for a bit and the voltage was 14.5V when we started again, a few minutes later 5-6V.

So I checked the AC voltage before the regulator and found 2-3V AC. And an open circuit AC voltage of 100-300V depending on rpm. My guess is I have a CDI high voltage stator and the voltage regulator could cope until it got hot and then shunted everything to ground. But would work again briefly when it had cooled off. I need a lower voltage generator stator.

A few speed secrets from inside Av's F4 engine. Double row self aligning main brgs, left hand main brg is a slip fit on the shaft, RD125 rod, double ring TS125 Weisco piston with 1mm rings and champhered flywheel rim on the inlet side.

Northerns do three bond so any bike shop should be able to help.

Thanks .... Gigglebutton saved the day with a half tube he had at work and I am off around the bike shops this morning to get some more supplies while Chambers prepares the engine for re assembly and a buzz up on the dyno this afternoon.

Chambers has put a lot of work into Av's F4 bike and she is real keen to ride this weekend if she can.

Hopefully we will get to see a bit of this sort of action at Mt Welly Sunday.

Any decent bikes shop will carry it. If they don't, Smash their glass counter top with your bare hands, and shake you glass shard encrusted fist at them, call them Nancy boys and scream that you won't follow their evil ways and don't subscribe to Soichiro Honda's apoplectic Final Solution of a 4 stroke world.

that looks like Cr125/250 stuff. Rewind alternator coil I suspect. Measure resistance, then heat up above 60 and should change 15% but no more.

The other issue is that you havnt lifted the trigger from ground.
See the green wire screwed to the stator, this is connected to the green trigger wire.
The blue trigger wire is sensor ground, the green ( with earth disconnected ) is trigger +.
Early CR125 rotor and stators cant supply enough current to run an Ignitech.
The early stator run with a late model rotor that has super magnets will do it, and visa versa as the later stators have much thicker winding wire for more current/less voltage.
You can spot the super magnets as the rotor wil go "clunk, clunk " as you rotate it slowly, the old magnets do virtually nothing.

Pretty good eyesight there Wob.

interesting to know re changes. That is an older flywheel as the newer ones have beveled edge and not clearly separate top hat inner.

[TZ350]

OK .... thanks, it looks like we need to re wind the stator then.

[wobbly]

Get em for a hundy from Ricky.

OK .... thanks, it looks like we need to re wind the stator then.

Will it ready for tomorrow ? Going to be a nice day ?

Wobbly, this is one of the high powered one I got from you.

Heaps of aftermarket on eBay. 50w upgrade too
Yeah Ricky stator rings a bell. My std 40W runs igni, water pump and a few other things and never drops in voltage in all gears run.
