Yamaha Blaster Titanium Flywheel Nut
The Yamaha Blaster titanium flywheel nut with steel washer provides a lightweight replacement for the original flywheel retaining hardware. This combination weighs 8 grams less than the OEM nut and washer.
The titanium nut features a hexagonal drive and flanged base. A separate steel washer is included for installation.
What is included
- One titanium flywheel nut
- One steel washer
One set services one flywheel mounting location.
Application and weight reduction
Designed for Yamaha Blaster flywheel hardware replacement, this set is an option for engine builds, restoration projects and flywheel service.
The 8-gram reduction applies to the nut and washer combination compared with OEM hardware. It is a hardware weight reduction; it does not represent the same change as machining and lightening the flywheel itself.
Works with all. Yamaha Blaster factory and aftermarket crankshafts.
KOR installation instructions
Inspect the crankshaft threads and mating components before assembly. Apply anti-seize to the threads, install the supplied steel washer and titanium nut, and tighten to 48 ft-lb (approximately 65 N·m) using a suitable flywheel holding tool and torque wrench.
This is KOR’s installation specification for this titanium nut with anti-seize on the threads.
