best product and method to clean fins.

You guys are sick.

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.
