After 20 some odd years of riding I got my 1st Harley, a used 2007 FatBoy.
The engine has diamond cut cooling fins. Some of the fins a have some surface rust on the diamond cut edge. Whats the best way to remove the rust? Ive been trying 0000# steel wool and elbow grease but its not working very well. Any Ideas?

Thks

 

Ain't rust buddy your fins are aluminum and you've trashed the finish using steel wool on it . Only hope you have now it some kind of aluminum polish and lot of cussing . good luck ...........

 

 

A Dremal with some metal dies will get the luster back but tedious and time consuming.

 

A dremel with a cotton buff pad and some really light jewelers rouge .Would be what I use.The cotton wheel would be one of the sewn ones.Then you still beed to be careful so you dont make to big of a cut.

 

Like said before the fins are aluminum.They don't rust,they corrode.

Your gonna have to polish them,hope you are patient!

 

IT wouldnt take me long to polish them------------the cleanup would take longer

 

How about new juggs, bigger bore...problem solved.

 

that would work but the people who diamond cut are probably 2 years out now on getting it done

 

I hate it when my aluminum gets rusty...
