1969 Honda Sandcast CB750 Fully Restored

Up for auction is a 1969 Honda CB750 Sandcast. restored down to the nuts and bolts. Frame #4286 with engine #371. Frame and motor not original to each other. I bought this bike a few years ago. It came to me with a K1 motor. and many of its original parts missing. I located a very early motor (#371) and rebuilt it all from the ground up. I bought as many NOS and genuine Honda parts as I could. and rebuilt what was salvageable. Unfortunately. it is not an original survivor bike. but now that it has been restored to like-new condition it can really be enjoyed again. New Yamiya ducktail seat. and bodywork in Ruby Red. Very solid 'non-paragraph' HM300 exhaust pipes without the EPA warning stamped on later pipes. Pipes have some rash at the outside on the rear tips. The #2 pipe has been professionally patched and painted where it can't be seen. 9-hole clutch cover. Recessed ignition with plug key matching the fork lock. and spare NOS non-plug key. Original double-cut front fender. and 2-bolt rear fender. Freshly rebuilt gauges by Lecram. Cylinder head and cylinders are pressure-cast. or 'sandcast' just like the cases. and the head does not have the top-front bolt added on later K0's. Left side fins on the head have some damage from someone removing it long ago. I decided not to risk breaking any fins and leave them as-is. The very early motor was never damaged by chain-breakage in the sprocket area like so many sandcast motors were. The sprocket area is in perfect condition. Motor rebuild included: New transmission bearings New crankshaft main bearings New Honda primary chains CycleX primary chain tensioner Oil pump rebuild New Honda cam chain and tensioner assembly Cylinder measure/hone Piston cleaning New . 50mm over rings Valve job New Honda valve tappet adjuster screws Original cam and rocker assemblies were in excellent condition All new seals and gaskets Other parts rebuilt or replaced: Wheel bearings Brake shoes/pads Brake piston seal Brass swing arm bushings Tapered steering bearings Wiring Harness replaced All black parts painted with 90-percent gloss - no powder coat used.

American racing's governing body. the AMA. had rules that allowed racing by production machines only. Honda knew that what won on the race track today. sold in the show rooms tomorrow. and a large engine capacity road machine would have to be built to compete with the Harley Davidson and Triumph twin-cylinder machines. Hansen told Mr Honda that he should build a 'King of Motorcycles' and at the Tokyo Show of October 1968 and the Brighton Show of April 1969 the CB750 was launched. Hansen's race team's historical victory at the 1970 Daytona 200 with Dick Mann riding a tall-geared CB750 to victory saw Honda cease all motorcycle road-racing activities and the beginning of the era of the 'Superbike'. The earliest CB750′s had gravity cast engine cases erroneously referred to as sandcast. The early engine cases. which were made prior to the completion of production casting dies. were actually cast using what is correctly called permanent mold casting which uses metal casting molds not sand. It is the gravity casting method and the molds that results in a rough finish to the part. A $500 deposit payable by Paypal will be due within 48 hours of the auction close.
