NHTSA recall 79V065000
Engine and engine cooling › Engine
Honda CB750
The defect
If the countershaft oil seal IS subjected to extreme oil pressure variation, the countershaft oil seal may be split, allowing oil to leak. Leaking oil can come into contact with the rear tire, which can result in traction reduction.
The remedy
Countershaft oil seal will be replaced and a modified "oil path body" will be installed to reduce the oil pressure at the countershaft oil seal. Repairs will be performed at no charge to owner.
