Thanks Resto Fan.

BJ I'll take some photos of the wiring if the offer's still there it'll be a big help having someone being the guru.
I can't believe how close this is getting.

MickB, I was looking at crankcase photo, I think it was at 471, no grease in primary shaft bearings there, did you smear them before the clutch went on? You said you cleaned them out along with the cam, but my question is on the other end of the primary shaft...the needle bearings in the basket behind the oil pump...You didn't grease them too did you? I have found crusty grease there in other old engines. That grease won't break down , especially in that area. Just askin.

MickB · « **Reply #603 on:** February 25, 2015, 11:16:52 pm »

Rb thanks for reminding me, I remember smearing a little grease in the needle rollers just to keep them in position, I'm not pulling the motor out to see.
The rest I mustn'tve put any on, it's a long time ago and at my age I've forgotten the exact specifics of what was greased, but it all sounds like it's worked out.

You aught to have been transported like my relos, then no probs, plus you'd get decent fish and chips.
Ground in auto, earth in houses, go figure!

BJ I put the generator cover back on and as suggested kicked it over till oil came up to the cam bearings and filled the little catchments., all good, oil coming up beautifully.

always good to know, not far away now mate

MickB · « **Reply #608 on:** February 27, 2015, 12:44:16 am »

I've only got the tappets to do tomorrow, chain is on and adjusted, pretty much all the mechanicals are complete. I need to check each nut and bolt is tight.

Then to start on the electrics, of which I've been procrastinating. Then do the points.

Waiting for the new clutch rod to arrive, hopefully next week.

Also to put the rest of the carby tubes on and correctly route the starter cable.

MickB · « **Reply #609 on:** February 28, 2015, 02:00:47 am »

Well you never get done what you want, there's always something else to be restored.

Electrics arn't my strong point, but I've got to finish the electrical heart of the bike, so far.…

I haven't been able to find the correct 9 blade pin plug anywhere, anyone have advice? I bought some from Eastern Beaver, very unhelpful no sizes given, the 9 pin I bought is tiny and won't fit the plate. The bloke wouldn't help so I ended up with the wrong part.

Cleaned the rectifier and installed new pins on the wires from the rectifier, the electric plates I have some that are blades and others have pins, this is goings to take some time to restore and work out. The new wiring loom has blade connections and the best connections I have are pin. I can't find a 9 pin blade connection that'll fit the plate aaaah!

calj737 · « **Reply #610 on:** February 28, 2015, 05:50:58 am »

Bummer! You might need to cut the pins off and install blade type male ends, Mick. I know you'd rather not, but absent of locating the correct vintage round plug, I'm at a loss.

MickB · « **Reply #611 on:** February 28, 2015, 12:27:36 pm »

Thanks Cal, after rereading my thread I didn't make it clear enough.
1st I'd rather find where to get a 9 blade type connection that fits.
2nd I bought a 12 pin connection that sort of fits, it'll do the job but I'm not happy about it.

Valhad · « **Reply #612 on:** February 28, 2015, 07:28:30 pm »

Mick, if I read that right, you're after the sub harness with flat connectors? Cause I've still got one of those of you need it.

MickB · « **Reply #613 on:** February 28, 2015, 10:18:13 pm »

Valhad thanks, I'll take a photo and send it along with the dimensions of each of the slots. If it's the one giddy up.

MickB · « **Reply #614 on:** March 01, 2015, 12:22:10 am »

Valhad here are some photos with dimensions. I need male and female sides. The new loom has blade connectors thus my dilemma and need.

A connector that needs replacing.

Valhad · « **Reply #615 on:** March 01, 2015, 01:38:05 pm »

The sub-loom I have does have that connector. I also have a less nice loom (no wrap/tape on wiring, couple frayed wires) with that connector, if you don't want the whole panel sub-loom piece I'd lop the connector off and mail just that. Both panel-loom connectors are used condition, but totally intact - the complete loom connectors have a bit of greening from corrosion.

But, I don't have the main harness side one. At least, not that I have found yet. If you're interested in half of the solution, let me know.

MickB · « **Reply #616 on:** March 01, 2015, 01:44:15 pm »

Mate I'd prefer to just plug in and go, I see there's a difference to 500 vs 550 sub looms. I'd prefer the better one of the 2 your suggesting, but if the lop off is a good one I'll go with that, BTW which photo is it on page 1 of your for sale parts? So I can see, I need the middle connectors male and female ends.

MickB · « **Reply #617 on:** March 01, 2015, 02:05:40 pm »

Valhalla I'll tell you what, if photo 30 of your for sale stuff is for a 500, I'll take the loom and the male and female connectors, also the rectifier that has the red plug, save cutting it I'll take the rectifier with the plug attached (I hope the rectifier still works). Regards
Mick

Valhad · « **Reply #618 on:** March 01, 2015, 02:06:34 pm »

This is the sub loom I've got. I have two more of the same male 9 pin connector, but none of the female side that holds the blades.

This is the corroded one, obviously. The two that are essentially loose are less so.

MickB · « **Reply #619 on:** March 01, 2015, 02:08:55 pm »

I'll pm you

bryanj · « **Reply #620 on:** March 02, 2015, 05:00:29 am »

The pin one is very early 500, the blade ones are later 500 and 550. Th eblock you want is the same on all later 500 and 550 mate

MickB · « **Reply #621 on:** March 02, 2015, 10:09:51 am »

BJ thanks, I've worked out that I have 2 options with the parts I have.
1st Use the plate I've restored and because I have a 9 pin plug coming from the alternator I could cut a piece from a an old plate (has the small pin style) and rivet it to the restored plate. I would end up with two blade style plugs and a pin style in the middle slot.
2nd Rewire an older style plate with all pin style (I've all the pin styles male & female ends).

Both are options, I'll probably go with option 1, but I'm not entirely sure yet.
Because I have 2 different plates, either way I have to work out how to extract the female end of the pin style to order rewire it to the plate. Does anyone know how to get the female pins out? I've worked out the male ends, just push them out.

One issue I have is to ensure I wire up the plug to the rectifier correctly as it plugs into the alternator and they both have 3 yellow wires, I presume I had better make sure the correct male end yellow wire goes into the correct female or I'm going to have trouble.

I need to sit down and look closely as to the best course, and as I write this it's becoming clearer to the best option, I think - now there's an oxymoron.

Also because I'm getting close to the end I'm wanting to finish it, BTW new clutch rod came yesterday, it's as new!

As one small bonus to ease your mind, the order of those three yellow wires shouldn't matter. As long as they all end up at the rectifier, you should be just fine.

MickB · « **Reply #623 on:** March 02, 2015, 11:33:08 am »

I wondered about that, but that's great to know thanks very much Valhad.

DH · « **Reply #624 on:** March 02, 2015, 11:37:43 am »

Just to let you guys know, and not to interrupt, I have the 9 pin connector block (both halves, main harness/stator harness) in the older pin style. If this will help you mick, let me know. Just throwin this out there...

EDIT....just checked, I only have the STATOR harness with 9 pin connector. I'm late for the party, so again, sorry to interrupt, but if you need that harness, it is intact, and available. I'm guessing it plugs into the sub harness? I already sent that to a guy in the UK, (trigger?) i believe. ...good luck either way, and hope you guys get it sorted.
