1500cc - Yamaha YFZ450R, YZ450F

My engine build needed more fuel at high RPM, and this 1500cc injector delivered the flow without any adapter hassles. It’s a true direct-fit upgrade that took maybe twenty minutes to swap in.

Swapped out the stock injectors on my YZ450F and these 1500cc units fit perfectly without any adapter hassle. The fuel flow is noticeably steadier at wide-open throttle.

I was a little nervous about upgrading the injector, but this one was a direct fit and my YFZ450R started right up. The increased fuel flow is exactly what I needed for my bigger jets. Feels like a solid piece of hardware for the money.
