TopHarley Davidson m8 107-114 stage IV Kit
Genuine harley stage IV kit to suit 107 m8. This kit spent only 1000 k’s in my bike then I did a full engine big cube build. This kit was run in properly and made excellent horsepower and torque.this kit will offer over 50% more power over stock. NOTE: this kit does not come with the clutch as it’s still in my bike hence the big reduction in price over new ($5800 with no pipe) As with all stage iv kits you will need to supply your own air cleaner to suit the 64mm throttle body in the kit.
