Wheels
Safety depends on the quality and condition of your wheels and brakes. Replace those wheel bearings, they are probably older than you are! Get rid of those tin cups and felt washers. Upgrade with new bearings, double lip seals, respoked wheels. We can re-cut the braking surface of your hubs to give a brake surface which is flat and concentric to the axis of your wheel.
We'll disassemble wheel, sand blast hub, and re-spoke and lace with new stainless steel spokes and nipples. You can also get new aluminum or chrome steel rims for your wheels.

Engine service upgrade and rebuild
Cylinder heads- basic valve job. Disassemble, clean and beadblast heads; inspect and measure springs. Install new valve guides with stem seals. Re-cut to 3 angle valve seat. Dress 45” on valve face. Black Diamond one piece stainless steel stellite tipped valves (I recommend replacing valves, if necessary, as a set-- If one is worn out-of-tolerance, then the others are usually pretty close).
Additional Engine Services: If your springs are fatigued and have lost lift, I can shim them to boost pressure; or, complete new spring kits are available R69S, R69, R68-- spring kit for two heads R50 through R60/2-- spring kit for two heads.
Note that late in 1966 BMW upgraded their valve stem type to a rotating design. All replacement valves are of this improved type and require the use of appropriate upper spring retainers and grooved keepers. We offer titanium retainers for their greater durability, strength and lightweight characteristics, along with offering steel keepers.
