1978 Honda Cb750k Engine / Motor All New Bearings on 2040-parts.com

These cases I have had for 2 years. They are from a 78 but will fit in any sohc bike. While there are several differences the only one you may need to be concerned with is the sprocket carrier. If you have anything other than a 77 78 you will need the piece that your rear sprocket is bolted to as it is out more than the earlier models to accommodate the stronger final drive bearing.

This engine was low miles and perfect condition. I changed the 1 st gear. Installed new bearings on n the crank and rods. The cases were Bbbbb and the rods were 4's which equated to green crank & yellow rods bearings. I have had the cylinders boared to 62mm and have ported and polished the head. If I thought someone would actually pay for this work I would go ahead and put it together. As it is this is a very nice engine in near-perfect condition and ready to run. The final drive on this model has 50 teeth ILO 55. The bolt holding it down was changed to an 8mm bolt ILO a 6mm. This was Honda last and fastest single overhead cam CB 750 k engine.


A man from Texas had called and wanted to build a faster engine for his bike. I suggested a 1 mm over bore . Back in THE DAY , if you were going to face your cb750 it would have been a 62mm overbore. This is my engine of choice. I also have an RC engineering 296 cam with titanium Keepers and Springs and shims.if you are interested in the Complete deal text me 404 545 7697. Otherwise I'll be riding this bad boy in a couple of weeks:)

Thanks for checking it out. Miles
