I’ve loads more of various stages of disassembly if anyone wants to see them.

Replaced the chainring and sprocket.
Certainly reduced some of the free play at the drive shaft.

Not sure about this lot.
Over enthusiastic shambles on eBay.
Speedo is kph and tacho is electrical.
Off the scale incompetence.
Also looking a bit small maybe?
I can live with kph but is it poss to get a signal to the tacho some how?

Thanks I’ll give that a go.
Is there any risk of half revs off one coil or do I link to both?

Terrific, thanks gradually getting there. Currently sorting real wheel, sprocket, chain etc.
Planning lithium battery, just working through some conflicting information or reg/rec replacement.

Sheered a bolt in the clutch centre plate - part No. 22120323010.

Anyone got one for sale?

Thanks

Thanks to whomever gave me this piece of advice.
Bit of welding and fit fine without the rubber washers.

And now this lot.

Anyone see a problem with this set up?

Register · « **Reply #61 on:** April 26, 2020, 02:33:07 AM »

Still creeping forwards.
Got to the unintelligible ugly stage.
Ricks regulator - I understand the bit where you match the 5 and 3 cables up but could anyone clarify what’s meant by the attached photo from their site......

‘DO NOT wire in at the 8P connector......’

I assumed that I just reconnect these to their other halves.
Is that not right?
Thanks

Still struggling with the wiring but it now turns over and the oil light goes out.
Not that you can tell from the photos.
Could someone remind me when the ignition light comes on and goes off?
Currently nothing.
Thanks

Sorry, my previous post makes no sense as I refer to ignition light but mean neutral light.

1 week later and still having no success I can't get any power at the points. I have continuity (blue and yellow) from coils to points

In summary, I have;

ignition - cranks well, oil light goes out promptly

headlight - main and low beam ok

indicators - front only, not flashing. Rears not connected

horn - makes a noise

no neutral light - bulb ok

And a spare black terminal on the harness where the coils join.

Any help appreciated thanks.

I think I’ve got the wiring sorted. Everything works but I’m not sure it’s as it should be.

ignition on powers the starter motor but the kill switch powers the coils/points even if ignition is off?

Do I have it right?

Finally got the exhaust on.

If I can find the plug spanner I’ll have a go at staring it tomorrow.

Thanks

Now running for first time since 2012 and in much need of a silencer.
Answered my previous question - switching the ignition off doesn’t stop the engine. Only kill switch does.

Assume I just need to find a switched power to the kill switch and that will bring everythinG to spec

Sounds like this

What looks like a pattern part coil (shorter length) just fried itself. Too hot to touch, now nothing.

Anyone know if I can run incandescent indicators up front with LED at the rear?

Thanks

I could use some help on the brake callipers.
I plan to run with banjo fitting direct to calliper.
Anyone got a method to remove the insert that’s preventing the bolt from running in?
Thanks.

I used a drywall screw, maybe 1.5"? Anyway, long enough that you have something to grab. Gently screw it into the insert, then lever it out with some pliers. I don't remember it taking a whole lot of brute force, but it has been a few years since I did it.

Register · « **Reply #70 on:** May 31, 2020, 09:22:25 AM »

Thanks. Assume the insert is press fit, not threaded?
Also there’s a small lip on the calliper did you bother to file that off or just seat the copper washer in there?
Thanks

Worked like a charm. Thanks.

seanbarney41 · « **Reply #72 on:** May 31, 2020, 10:34:42 AM »

I did not file the lip off, as I was not intending to use a banjo bolt...i used 2 hardlines on my dual disc setup. I just needed to move the insert to the bleed screw hole so both sides would be symmetrical.

Also, check the bike out in bike of the month. Close battle going on. Could use a vote.

Terrific bike.
i could never have got behind those rectangular mirrors.
