Here are some pictures of the engine as I did the tear down to the frame. I had cleaned it with solvent-based engine cleaner to get the top layer of built up oil and grease off it before I brought it into the work shop.
Cylinder, Valve Cover & Exhaust Nut Bead Blasting
There is a local shop in Arvada, CO, Roadies Performance, that does bead blasting for me. They build customer Harley’s and are great folks. If I can, I like to spend some of the money for a rebuild in the local community. I took the cylinders, valve covers and exhaust nuts for blasting and got them back in a couple of days. It cost $83.00.
I scribed an “L” and “R” on the top of the cylinders. Here’s the final product I got back.
Good as new.
I sent the heads to Randy Long at Long’s Mechanical Services in Pennsylvania for inspection and repair. I figured the exhaust seats would need to be replaced and I asked for new valves, seats and guides.
I don’t believe Randy has a web site and I’m not sure he has a business Email address, so I call him when I need some work done. He’s been building heads for quite awhile and works on BMW, Harley and British bike heads. I think he got started when he was racing a Harley drag bike. He rides BMW iron and has been out to Colorado a couple of times riding, so I always enjoy chatting with him on the phone.

I just got the heads back from Randy. Total cost was $490. Here they are good as new again.
Air Box Clean Up
I cleaned and polished the air box covers as shown below; before and after.
As noted in other posts, I start by cleaning in my parts washer with a tooth brush and soft stiff nylon bristle brush to get as much oil and grease off the parts as I can. I use Scotch Brite pads with AutoSol aluminum cleaner to get oxidation and baked on crud out of the rough casting. Then I use “00” steel wool with more aluminum cleaner until I get a nice luster. I follow this up with AutoSol aluminum paste polish to add some shine and finally, I finish with AutoSol Aluminum Protective Oil to help keep things looking new for awhile.
