The inlet rubbers look just like the ones from the carbed SS models. I don't know if they are the same but it's worth a look.

I thought if nothing else you would have the part number to help find it local
YA never know who has what layin around and if they don't have to look it up on an old fiche they may be more inclined to look on the shelf


I personally have shipped several items to Australia and it has never been anywhere near 50 usually under 15 insured Aholes everywhere :thumbup: :banghead: :banghead:

I got the rear wheel cleaned up after not doing anything to it since the last post.Anyway it looked like this.

Image

Image



And now looks like this.
Image

Image

Image

Image

It's not perfect and I was'nt going for a mirror shine so I'm happy with it.Better than it was anyway.

I also pulled some bits out of the Mollasses bucket and hit them with a wire wheel.They came up ok too.You can see how pitted the bolt was from rust.
Image

I'll start on the back rim next.The front took a lot of hours so I'm not looking forward to doing the back :banghead: :lol:.I also started rubbing back the headers.Now after seeing G's excellent job I think I might spray mine chrome or silver.I just can't live up to that standard :lol: :lol: .
I've now got 2 choices with painting the frame.Powder coating or spraying it as both will be done for virtually free ( case of beer ).Decisions...decisions.I like the idea of powder coating but am doing it through a mate of a mate.The only trouble is I like to talk to the person actually doing the job to be sure it's done right.Whereas I know the spray painter personally.No hurry though so I'll think about it :wacko: .

Later

just wow, I didn`t believe it was possible to get the rims so nicely looking again :thumbup:
My old ones look almost like yours did. I was thinking what to do with them as I have a set of brand new ones on the bike now. Can you give us some more details what you exactly did ?
I was always thinking that when polishing the rims the critical part would be the edge to the paint and the small silver section on the 3 spokes but that looks really good on your rims.
Guess you will have to wax the rims or do something similar as the aluminium is blank and will corrode even faster but maybe that`s less of a problem in Australia`s climate than it is here.
Don`t forget to polish the outer edge when the tires are taken off. :wink:

Cleaning the header should not be that hard. I did the mistake to sandblast mine which left a rough surface which needed a lot of sanding to become even again. It should be easier for you.
Headers get a lot hotter than exhausts so many "heat resistant" spray paints will start to peel off over time. Better invest some elbow grease. :mrgreen:

Thanks G.As you well know nothing is easy but here goes.First I had to remove the front wheel and the disc from the side I was working on.
Image

Image

This is what it looked like.
Image

Image

Image

Then find a shady spot to work in as it's the middle of sumer over here.
Image

Image

Now on with the paint stripper to get the plastic coating off.
Image

Image

You usually won't get it all the first time.When it comes to putting it on close to the paint I use a small brush and patience.
Image

Image

Image

Next up is the hard work starting with this.

Image

I use these now when sanding.Saves the fingers a bit.My wife bought these.Of course I would have bought red ones as red is faster and I would have done the job in half the time :thumbup: :lol:
Image

More to come as I progress :thumbup:.

Where was I...oh yeah.This is what it looks like after the 80g wet/dry.

Image

Image

The 80 wet/dry part is the hardest and longest.Next up some 120.After the 120.
Image

Image

After that I used some 600,1000 and 120.Then I use this for a couple of minutes.
Image

And finally tidy up with this.
Image

Here I've done one section to final completion.Came out ok.
Image

Image

You can see where I"ve stopped at the 80g and finshed the one section completely.As I said the 80 grit takes about 70% of the job.I'll probably finish the rest of the wheel through the week.

thanks, Andrew. Are the spots were the silver shows through under the red paint because of the paint remover ? If so it`s probably better to have the wheel standing and doing only the lower section, then rinse, then do the next etc. This`ll take a lot longer but it may be safer for the painted parts of the rims.
I`ll definetely give it a try in a couple of months. Currently we`re at -15°C :(

That's actually aluminium dust mixed with water from using the 80grit G.I had'nt washed the rim at this stage because I still had to finish the rest of it.The front wheel in the earlier pics looked the same before I gave it a wash.I just did a part of the rim to photograph the different stages.I'll post up photos when I have finished the whole rim and given it a wash.
If you look at the closeup you'll see where the oxidisation has got under the plastic coating on the painted part.There was nothing I could do about that but clean it up.I will eventually repaint the rims but it's a money thing (lack of) at the moment.
-15C :shock: .We forget how lucky we are over here having all year round riding weather.
