One of the old neighbours had a PY90 4 stroke version of a PW80, it got ragged mercilessly for a couple a years and was still running fine.

Has anyone been up to Olivers Mount? A ride up was half planned at work a few years ago, so after last years was cancelled I might see if I can clear a it of space in the diary for the Barry Sheen Classic.

Question :  Does anyone have real experience of rebuilding cast aluminium engine cooling fins neatly ?

 

Those on one of my Sunbeam engines have been broken away by some clout (no it wasn't me !) who levered against them to get the cylinder head off.  It's a common problem on these 60+ year old engines.

 

 

^ Clearly the mechanics* never looked at the pictures in the manual, nor did they learn their first try, nor the second ..that there are two cylinder-head nuts inside the cam-chain tunnel that also needed to be undone.!

 

In the past I've tried having pieces of aluminium welded in but tbh it wasn't totally successful, nor very neat ..and even before being reassembled the weld line was cracked again..   Apparently welding thin cast aluminium from just one side is not so easy.   I know some owners have tried adhesives to fit pieces of aluminium in these places but of course we are talking about the fins getting hot and also subject to the vibration of a twin cylinder engine. 

 

How do you, else else quality restorers do this sort of repair so that it is an invisible repair.?

 

Thanks,

Bfg

I've used HTS-2000 alloy brazing rods to good effect repairing cast alloy parts, even magnesium alloys. Only small parts mind as I only have a Mapp gas torch and you need a LOT of heat as aluminium is such a good heat sink. If you have access to oxy acetylene then that shouldn't be a problem.

Thanks that looks like it might work well, and also be fun to try. 

 

I haven't oxy-acetylene but I am prepared to use two or more blow torches, one or more with a wide-spread flame and the other to do the localised task. I've not tried but possibly the block might just go into the oven ..to be preheated a couple hundred degrees. I'd normally farm this sort of job out but ..as I say I wasn't overwhelmed with the perfection* of the last one I had weld repaired. And if this HTS2000 really does work as seen in the video (it looks quite like a cross between soldering and leading ..which I once tried when I started in the motor trade) then it will be a really useful knowledge base to have for other repairs.  I love the idea of filling around a stripped thread for example, and all too often prior owners have cracked or badly scored other parts like the cast aluminum rocker cover or broken the headlamp bracket 'ears' off these bike's fork shrouds.  

 

I see it's available on ebay at £20 for x10 rods. or £32 for x20 rods.  Unfortunately there's no indication of the size of those rods nor how far they will go ?   I'll do a search and see if I can find quantifiable information. 

 

Again many thanks,

Bfg

......... scuttles out to garage with measuring tape. The rods are approximately 390mm long, 2.25mm diameter and according to my kitchen scales weigh 10g. You really do need the stainless steel wire brush as well to get a good "tin" on the surface and a carbide burr in a dremel is really good at cleaning up the work prior to starting.

any interest in 13 plate honda cb500f 50500 miles mot till nov (ill check) top box

 

edit mot beginning of june (feck) - likely get another at easter

Me too-just have v-twins and single cylinder two strokes now. And there is a distinct feel between all of them, where as I found all in line 4's feel pretty much the same as each other

Just bought the Gixxer replacement.

 

V-twin ftw 

 

And hardly anything has fallen off.....

Thanks.. that is useful, insomuch as that's 1.5cc in volume, and as I can measure the cooling fin's area / volume that I need to recreate - then I'll know how many rods I'll need as a bare minimum.  Add say 50% for experiment & waste and I'll be good to go.

 

I have a set of burrs, so just need to order a high-temp flame thrower with some Map-x gas, and a s/s brush (cheers ).

 

I did have a look at the instructions ..and was thrown into confusion re. temperatures. That is until I realised they still talk Fahrenheit, which as far as I'm concerned is 18^th c German.

How fast does it go Mister?

[Cavcraft]

Dropped the scooter off for it's second service yesterday, it's only done about 1,100 mile in total but best to get it done as it's not had much use and stood for ages. Last time out it seemed to fizzle out around 70mph and wouldn't go any quicker. Not noticeably coughing or missing, just wouldn't hit previous speeds. They're quite fussy on fuel, possibly it was old/cheap juice, so lobbed about £8's worth of Shell's finest in and caned it up the motorway. Later on, on a private test route, it did 76-ish.

 

Anyhow, the shop it's gone to be serviced at have a new (TT) 200 coming soon, praying it's not black as I'll probably end up buying it. He reckons there's a £250 'chip' available for them too for a good bit of extra poke, on the older (TL) ones it's eight hundred odd quid for a stage 4 kit which seems a bit excessive, tbh.

Quite fast young man, in a stylish kinda way.   italian...oooer

[Jerzy Woking]

I've four stylish Italian bikes (OK, so one is not a v-twin, but looks like a 916 head on) and won't rule out a fifth.

 

However, a single cylinder bike made in India is taking my fancy at the moment

friend has one of those and loves it - has a triumph tiger and they get used together

RE?

 Reckon so.

 

dupa-dupa-dupa....

[Jerzy Woking]

RE?

Yes-a Himalayan. Going to borrow one for a couple of days when I'm in Spain next week. Think it will be excellent for plodding around on the huge number of tracks near the house.

 

Never really strayed onto unpaved roads before, but everyone says the Himalayan is easy to ride on tracks, so think it might be worth trying out, seeing I want to explore rural Spain. The Guzzi is great for the tarmac roads there, but has very, very limited ability on unpaved roads (as I found out in Albania last year).

Well , that’s the Versys on eBay . Bring on the morons

What's the twin like, Sam? Bit vibey or quite smooth?

Where can I buy spares for my 1984 Honda Vision Moped?

 

Following the Failure to proceed of the 1984 Honda Vision last year I gave it to a friend to have a look at. He reported two things firstly a blocked petrol hose, which I am sure we checked and was free running, but that was 8 months ago now! Easy to replace anyway.

 

The other problem was the rubber connecting pipe from the air filter to the carb is broken and hanging down partially blocking the carb intake.

 

Best place to buy a replacement?

[Cavcraft]

Ultra Womble is your man here, Mr Cylinder.

CMS in the Netherlands have the best online parts catalogs of any bike spares supplier. 

 

https://www.cmsnl.com/honda-scooter_model3/

 

Although I'll use them for big orders for single parts postage for small orders is high so I use their site to identify the Honds part number then either have my local Honda dealer order it in or order it online from Fowlers of Bristol who are the biggest OEM bike parts mail order supplier in the UK. Also worth checking the Honda P/N on ebay as sometimes people clear old stock through there.
