I feel your pain, I've been waiting two weeks for spark plugs that were advertised as in-stock but so far nowhere to be seen!
Was the old sprocket worn out? I was lucky with Ratty because although the drive chain was seized solid the rear sprocket was perfect apart from the PO having it chrome plated! I had that removed and it was refinished in BZP and it has come out like new.



The old sprocket was worn, corroded and was in overall poor condition. I didn't want to use it with a new chain and front sprocket - rightly or (probably) wrongly I slung it. I'll have to wait and see if the other one due next week is ok. And yes the simplest little brackets and fasteners are like hens teeth.

Just took delivery of my rear sprocket and it isn’t the correct one! I got mixed up in my earlier post, the sprocket that’s arrived today is from Wemoto which I ordered after the eBay episode.

It’s out of stock at DS and CMS. I tried two suppliers on eBay, one has no stock despite listing the item. The other reported “stock issues” after I asked for a refund and then a day later promised delivery for next week. The item is now apparently on its way.  I feel a saga coming on….

A few updates. I’ve soldered new HT leads in the coils and completed encapsulation with the recommended RS epoxy. Just need to cosmetically finish them off with some Milliput. I was concerned about too much heat input when soldering and used fine nosed pliers as a heat sink. The epoxy took a couple of days to harden fully, not helped by relatively low overnight temperatures in the garage. Final electrical tests confirmed the coils have survived my efforts.

The powder coated brake and sprocket plates have arrived back but I’m still waiting for a rear sprocket which should finally arrive later today. The stock size seems to be in short supply with plenty advertised on eBay but which become out of stock when you order. My first order did not appear and I had to cancel and get a refund. The next supplier claimed 10 available but subsequently had “a stock Issue” now promised today.

My gauges arrived back this morning from Peter Horton who has done a fantastic job. I couldn’t resist a quick look on the bike, they really do look brand new.

I sent them to Peter because I could see traces of oil droplets inside the glasses. Peter found that the grease had solidified and the mileage counter wheels had stuck together which in operation would have stripped the gears or snapped the drive cable.

A good starting point would be Moffat just off the M74 which is very bike friendly. Hotels and B&Bs will give out route maps with suggested rides.
Theres a description of the area in my site with some good helpful links. https://alanmedlock.com/2021/09/05/three-lochs-run/

I have this problem as well on IOS so I always use a desktop for messages where I've have selected the check box under Personal Messages »Change Settings to save sent messages.

I may be looking in the wrong place but cannot see this option in Tapatalk to save a copy in sent items.

Looking great, like the paint job! I think it’s better to complete the engine on the bench as you’ve done. I found it a little awkward putting the barrels on in the frame.

I think you’re right. It’s not obvious in the photo but the lead was in a very shallow spiral path.

The rear mudguard, grab rail and some fittings have gone to Ashford Chroming who have quoted an 8 week turnaround which isn't too bad. Can't make my mind up whether to have the front mudguard replated as well or get an aftermarket replacement as it’s probably going to be more cost effective. However I’m not convinced that the aftermarket items will be to the same standard as a replated original mudguard.

My rear wheel arrived on Friday from Full Circle Wheel Building and I’ve put a K82 on, just waiting for the sprocket and brake plates which are at the powder coaters.

I’ve turned my attention to the electrics and I’ve started “Ashes fix” on the coils which are in good condition although the HT leads were in a terrible state. As mentioned in the procedure the outer insulation of each HT lead was hard and two of the inner conductors had broken. The coils cleaned up well and the leads were exposed in no time at all using a rasp. Now I know that the coils are good I’ll go ahead and order some epoxy from RS.

Can’t see how that’s justified, surely an error.

I had the same problem on my 350/4. I had to cut from the centre with a junior hacksaw  to the swing arm mount. The bush could be pressed out then.

Finally got the cylinder head and cover installed and valve clearances set. Unfortunately when I initially started to fit the head I found the original cylinder/head dowels were slightly deformed and far too tight in the cylinder as I tried to fit them. I’d forgotten that one of them in particular took an awful lot of effort to remove during disassembly and so I had to send for new cylinder/head dowels. Better to do it right but it was a frustrating wait. I now need to cleanup and polish the tappet and crankcase caps, can’t say that I’m looking forward to that job!

I think I’ve got the harness routing figured out and I now need to decide whether to try and fix the original coils (Ashe's fix) or replace with after market versions - not sure which way to go yet. The chrome on the horn is fairly good and doesn’t need replating so I’ve assembled that with the ignition switch and bracket (thanks Ian) in place of the handlebar mount that came with the bike. The left hand handlebar switch has cleaned up ok but the right hand switch has beat me so I’ve ordered an aftermarket version from DSS.

Phil at Full Circle Wheel Building emailed this morning to say that he would build the rear wheel tomorrow morning and hopefully I’ll get that back on Friday.

Well I’m surprised it’s freely available although it does say for professional use only.

Many years ago I used to mix relatively large quantities of HF with other acids to make a reagent for etching certain types of stainless steels. Head to foot PPE in a room with fume extraction and a shower activated in an emergency by stepping on a footplate. Highly corrosive and toxic.
I didn't realise it was used in alloy wheel cleaners, I guess (hope) its in a low concentration.
