I've just drained the oil and as suspected all the bits of the kick shaft are in the sump.

More worryingly, I found this in the sump.

Haha. It's true, I feel much much better now.
Thank you Julie!

Oh really? Well that's a little bit of light at the end of the tunnel then. I did read trigger saying he always replaces the circlips but it was after I had put the cases together.

It wasn't charging either but one thing at a time.

Sorry I didn't get a video of it running.. I was about to and then this happened.

Well it ran, and it ran quite well but I've had a fairly large disaster.

I started it a couple of times from the electric start then I went to try the kick and something broke or came loose in the kick mechanism. Now although the kick has a spring return, it's not engaging with the gears.

I am gutted as I guess the only thing I can do here is strip the engine again.

Thanks everyone for the input! I've put the points back on and it's got spark now on all 4, going to see if I can send the Dyna back for a replacement.

Brianj I'm glad you mentioned about the aluminium washers under the cam cap brackets, I didn't have anything there. I've added a copper washer so hopefully that will work. The bolt on the kickstand side was wet with oil so I know oils made it up there which is great.

I'm basically ready to try and start it I think!?

I just realised my stupidity asking, of course it wouldnt spark against ground otherwise.

52
Right so I've just done as suggested and it does spark from the wire that would normally go to the ignition.

What's weird is that the light I'm using for timing is now always on.
Using a multimeter between the wire that would normally go to the ignition and ground, there is 12v. Is that right?

53
Ok thanks for the advice, I'll give that a go.

Just a quick update as I've got no decent pics to share, I'll take some this week. 

I've got the carbs back from vapour blasting and rebuilt.
The bikes filled up with oil and I had it coming out the front where the filter goes before I put the filter on and now the oil light goes out when I crank it over.
How do I know if it's making it to the head? I cant really see much past the tappits and I've tried leaving the end caps off but not got any oil coming out there yet.

The main issue I have currently, a fairly large one is that I have no spark. I've got a Dyna S electronic ignition with aftermarket 5 ohm coils. I timed the Dyna as per the instructions. You time it at the advance mark and twist the counterweight to fully advanced and the light should come on then.

The coils did get quite hot when I was doing the timing so I thought I might have damaged them but they are still measuring at 5ohms so not sure. I need to do a bit more investigation, i've yet to test the pickups on the Dyna which should read infinite ohms on all ranges.

Any ideas on what else I can check?

Oil pressure: You need an idiot light, it doesn't monitor oil pressure in the M unit, but you do run power to the light from Aux 1 or 2.

Speed sensor: Correct, This is just so the M unit can track your rides/service intervals. You split the signal wire from the sensor to the Gauges and to the input on the M unit.

Reg/Rec: As Brian says, you can't use the original reg rec units (edit: with a lithium battery). You should also not use a cheap eaby unit. I bought the Ricks reg/rec, expensive, but they are tried and tested.

This is the best diagram I have found, It's also editable in illustrator.  https://technicalarticles.revivalcycles.com/hc/en-us/articles/360009106131-m-Unit-Blue-Basic-Universal-Wiring-Diagram

side note: The M Button will not work unless installed inside steel bars, so if you are going aluminium clip-ons, don't buy one.

Good info. I'll be needing it very soon!

57
I'm not sure I want to ask, but how much to tach drives get?

58
Going to have to wait for that unfortunately. The vapour blasters are backed up so it will be a few weeks. I've got the gear controls fitted up and the front brakes bled (twin disks are a bastard)

I also modded the original tach mount to make it into a plug.

Its really just the carbs I'm waiting for now.

Ah ok, so is there no rubber chain guide then?

They look yellow in the photo but they are actually standard dust seals painted gold.

60
Please can someone tell me the part number for what I'm assuming is the chain guide that's supposed to go here? I'm probably being blind but I can't find it on the parts diagrams.
