Cool. Any update on when you are back on the road? We'll have to organise a shed raid after the Wellington Crew have had theirs so we can all start pushing each other to get finished.
I sat in a meeting today in Melbourne where a salesman told teh customer he'd guarantee I would be full time on a project here for the next 4 years. Wasn't that why I took the big pay drop to leave the last job? Anyway, I'll be back in the workshop tomorrow night to pick up that grinder Very Happy

Dam Jon, well, at least Melbourne has good bike friendly streets and shops to wander.... I’m working on it even tonight as we speak! Ha-ha
The wiring is sort of coming to an end... cert guy back in town soon so shouldn’t be more than 2 weeks... yay!

Cheers, and enjoy regardless...

Bolted up all the polished stuff, 200 hundred dollars of stainless cap screws, mounted the new brake hoses front and rear with brake light switches, run wires through engine to battery box, set up new oil hoses to pump up to tank area,



Ran all the wires to the batt box; wired up fuse holder, ignition unit & switch, black box, main fuse, still got to connect plugs and run final bits... is there something I’ve forgotten?
Just need to search and see if I can leave VOES out, that’s the vac retard unit behind carb... I hear conflicting stories? Then there is another wire not need to run!



How am I going to fit it all in!!! Ha-ha...

that primary inspection cover is going to leak a bit or have you seal off the g/box?

it's a 'total loss' lubrication system like the old bikes, true old school, Jon is gonna have an oil can holder and take out his oil can & lean & down & lube it while he's riding - he also needs a lighter holder for that bic lighter - & that's not including the drink holder & cellphone holder
seriously tho - I think those holes must be blanked off? or does he have a belt under there instead of a chain?

The cam and sprocket covers are looking good. I'll be interested in what you find on the Voes. I have the same problems. I remounted the one on Sara's sporty on the S&S carb but its basically just on a short piece of hose and I don't think its working properly. I'd rather dump it if I can. Same on my Evo when I get round to it.

i saw somewhere that you can ditch the v o e s shit by earthing out the black wire that runs to it. theres plenty of different views. most say dont do it cause it will fuk up your timing etc. i found this comment on the jj tho.

[i]If you want to ditch the VOES you will have to put in a on/off switch in its place, off for start, and on for advance after its warm, remember to switch it off for steep hills or when lugging with the ole lady on the back, Called manual advance.......Roach[/i]

I got these two off XLforum, just trying to work out how to keep it open... do i ground or unground the wire... is the question!? ?

1. If the V.O.E. Switch is grounded and the ignition module has a wire (green??) connected to it then 'Yes' the module is in its - less advance mode of operation.

Try disconnecting the wire lead to the V.O.E. Switch and taping it off.

See if you notice any difference or "engine pinging" after fully warmed up and under full load or going uphill with a wide open throttle (WOT)?

Next take the wire and bare the end then place it under a screw/bolt/washer in order to ground it to the frame or engine and force the ignition module to go to the advanced mode.

Repeat your test ride and see the difference this makes to the response under lower loads or if it really pings while at WOT?



2. you don't need the VOES. You'll never notice not having it, the VOES wire needs to remain open (ungrounded) or closed (grounded)? To make it run on the power curve all the time. The only downside to not having it is a very small decrease in fuel mileage.
The last guys post... he made an amenment and wasnt sure and was corected so i want to see where it goes before i try... but it sounds good...

Will keep you all posted.

The other thing is I need to check somehow weather when I parked mine how it is now weather its open or grounded now!!!

But they are both saying I don’t really need it, apparently it’s mainly for emissions and other yank compliance drama stuff...

You can run without the voes conected Ive seen it done with no problems from memory all the vacum operated switch does is limit the the total advance of the ignition by about 10 degrees, and Im pretty certain if you leave the wire to the ignition module disconected it will run full advance and if you earth the same wire it will retard the timing pretty easy to test this with a timing light on the bike.

cheers

so would it ok to just leave at full advance all the time? could it lead to pinging, or should be ok because it would be the normal ignition timing anyway?

It would pay to check your max advance and check if there is any pinging, but I helped a guy who fitted a big side draught carb on sporty and we left the voes disconected and I know of a couple other bikes not using them and they run sweet as

Thought I’d give you an overall on the wiring, I have not counted the hours I’ve spent on this...

I’ve always shied away from wiring...(pet hate) so when doing stuff on cars and bikes was cautious... well this job entailed that I get in and replace the whole loom... tuff on the brain.

So I first got hold of a blackbox from Germany which makes it easy to wire all the handlebar buttons and main stuff like lights, starter, indicators, horn... etc, it eliminates all the relays into a small box.



With that wiring diagram and the factory wiring I was really confused so I scanned the workshop manual into a .jpeg and opened in paint, then I whited out all the stuff I didn’t need that the blackbox was going to do, so that left stuff like ignition stuff, oil & nutural idiot lights, brake light switches.. Etc.

Then I drew in the black box and put in its coloured wires and e-mailed the Germans with a couple of finishing questions and all is good... then blew it up to massive poster size (A1) in colour...

[/

I think having done and spent time doing this helped me kind of know the logic in how a few things work...

So the wiring began,so to make things a little easier I used 7 core trailer wires and only had to run two lengths from the battery box to the front and it worked a treat...



I used an original Deutsch connector up the front and a mixture of brass bullet and blade connectors in the box.

I have run an Odyssey C310 battery because it’s very small... now I couldn’t find anything on running this on Harleys except unresolved threads on different forums and no definitive answers... only one guy said he used it and it went good, and that was on a drag bike and he ran it between the primary belt drive to save space.. I did note some things relevant to me, it’s just running his ignition and no lights indicators and his bike is running for a couple of minutes at a time...



Well, to date, my bike isn’t on the road, but! it starts and runs the thing, it runs the lights and the charging system seems to be putting in more than is going out?!

I took off the handlebar switch blocks and put in some micro buttons and have found that there are different quality ones about, good idea but spend more for good ones. I have found two that are so sensitive and one stayed on when you turn on ignition so have to replace that. It caused weird things to happen; pulling off the offending corresponding wire fixed everything so it wasn’t too hard to work out. Ours are not the best of suppliers here and I see the buttons sold in various outlets in the USA, I did see one ages ago and I wish I had saved it, they had coloured wires available on the button switches ( 4 wire colour options) instead of just black and looked to be good quality, I did some surfing.. But when your specifically looking you won’t find! Aye.



Well, here it is, tight as a preverbal, but working none the less, I was quite worried for some time I’d got the box a bit small...





The only things I deviated from with the diagram was to eliminate the starter button, I am running the one direct off the starter and eliminated the kill switch using just the ignition, when I did this I forgot to put power to the coil, but no spark caused me to look harder at the, why? So there are tricks... to be learnt... thanks Scotty, I also did not put in the VOES, so am still working on whether to earth it or not, can’t find a definitive answer...

Now all this has been an exercise and after some riding and some time I will pull the bike down to powder coat the frame, repaint the tins and will re-wire with vintage-style braided cotton cloth covered wire, like some you can see in one of the photos.
