Honda CB350 Race Engine Build- 48HP

Sharing my build of a 1970 Honda CB350K full race engine. Techniques shown include engine assembly, piston measurement, valve spring setup, cam timing, dyno test and more.

This is not a full tutorial on everything involved with an engine build. It does not show porting, valve seat installation, oil cooler setup, larger cylinder studs, or special valve seats.

Motorcycles are dangerous.

It is the responsibility of the mechanic to build a safe engine. A blown up engine or oil leaked on a tire can cause a crash that may seriously injure the rider. This video is backed up with decades of professional motorcycle mechanic experience. This is not a how-to video for a novice.
