650cc - Polaris Slingshot

My Slingshot idles so much smoother now that these 650cc injectors are in, and the throttle response feels crisper through the whole rev range. The flow rate is spot-on for my setup, and I've put about 800 miles on them without a hiccup.

The install was straightforward and the 650cc flow rate gave my Slingshot noticeably smoother throttle response. Idle is solid now, no more stumbling when I'm cruising through town.

These replaced the stock injectors on my Slingshot without any fitment issues, and the 650cc flow rate gave my tune the headroom it needed. Idle stayed clean and the fuel trims settled right where I expected them to.
