Title: best product and method to clean fins.
Post by: Aristotle on February 07, 2010, 04:45:12 PM
Hello: I would like to know what some of the members here are using to clean thier fins with as this has been a problem ever since I bought the bike.

Taking a small brush and trying to scrub the fins doesn't do the trick. Getting the grasshoppers out and flies and what-not that gets lodged in there is difficult enough. That is inaddition to trying to get the fins back into a nice condition.

As of right about now, the fins have been dirty since I first bought the bike over 20 years ago. This has been a problem since then.

What kind of products or methods do some of you use. Please don't say  bring it to the car wash as that method is out of the question, I am sure you know this.

What I'm looking for is getting the air head back into a clean looking and more of a shiny look. Comparable to how the fins looked like after having purchased the machine.

thanks in advance for your answers.  :)

I've had some success with scotchbrite rotary mops both purchased and made up from sheet material.(http://)
Wish they looked this good now. I'll need to do them again come spring.(http://)

Take them off and get them media blasted.

Its the only way to do a full on job.  Although Barry has almost got there.

Poverty riders version of the scotch brite mops is to glue scotch brite to a tongue depressor or Popsicle stick and work it in between the fins. Time intensive but a good result as well.

I picked up the large rotary mop and the sheet material from one of the stands at the local Classic car and  bike show. They are fairly widely available though. If you search ebay with scotchbrite that will turn up any number of mops and sheets.

Lou, for the sheets of Scotchbrite, try an automotive refinishing supply house. Different grades (grits) are define by the color of the S'Brite pad. Lots of uses for these around the shop.

Woodcraft sells the Norton version of Scotchbrite in 4 grades - Green (coarse), Maroon (medium), Gray(fine) & White (extra fine).

My local Woodcraft sells an assortment of 2 each for about $12.

NAPA Auto also carries one brand, or the other in their paint aisle.

The green is pretty gnarley, the white can remove rust from a gun, without damaging the bluing (used with oil, of course).  I think that the maroon or gray would be best for cleaning aluminum - they both are grat for "brushing" stainless.

Again, the white is similar to 0000 steel wool - will remove light rust from chrome- followed by a polishing agent.

Yep ... often wish I had a hack bike to ride and not to worry about.  Trouble is I'd probably clean it up.

Check out these clever Australian made wire brushes designed for refinishing alloy on classic motorcycles.

When they wear you can cut them back for a fresh start.

This is a very informative web site with photos of the brushes being used on classic motorcycles.

They look like they need a lot of elbow grease and patience but the results are impressive!

I haven't tried them myself as they are expensive but they may also be good value, you can spend a lot of money on various cleaning products hoping that they might work. If you follow their 'Street Cred' link there are magazine reviews and even the National Motorcycle Museum UK use them for restoration work.

Cheers Bruce

Would such mops be available in a hardware shop, for example??
Your fins look good.
Also, how exactly would you be using those to clean the fins with, if I may ask.

EDIT: Never mind, most of the answers are above my post.

Thanks Rob.

It only takes one typical winter day's riding to get the same even coating of road slime pretty well distributed all over my bike.  It takes a lot longer to clean the bike than it does to get it dirty.

I did get it spotless before I pulled the cylinders; I should have got a picture of it then!

I'm in Cousin Ed's camp. I was bored last weekend so cleaned the 81's rear wheel as I was trying out the HF balancer. First time I've ever done it -cleaned the wheel- since I bought the bike. Not sure it was worth the effort... per Ed's thoughts.   Monte

Maybe not for cleaning fins but these look interesting for the rest of the engine:

They might be a bit savage spinning at 10,000 rpm in an angle grinder!

I have a brush that I use in my battery drill. Unfortunately I didn't keep the packaging, and it doesn't have the manufacturers name on it, but I used it to do a lot of the alloy on my engine and it will do in between the fins as well.
The bristles are a red fibre type and they are long lasting. The brush will polish the sand cast alloy and leave only minor 'brush marks'.

It's also very good for cleaning nuts and bolts and can be used with metal polish.
