Run a Firecat across a lake and stop to check the plugs or pistons and you’ll learn the EFI gives the laydown twin plenty of fuel; just to be safe. Those who run these engines on the dyno will tell you the same thing; the factory calibration on these models must allow some “wiggle” room for less than ideal fuel quality, and we all know a little extra fuel helps keep Casper the Friendly Ghost from visiting you.
So if a bone-stock EFI is a bit on the rich side, it’s not like you install smaller main jets and run good fuel; or is it?
The Injector Perfector is an in-line device that regulates the fuel flow from the electric fuel pump to the injectors. It uses good old Mikuni main jets to precision regulate (reduce) the fuel flow, across the entire fuel map. Simple, very simple.
Worried about burndowns? If the sled is otherwise stock, this device shouldn’t cause one. You can watch the plug color and piston wash, just like you used to, and you’ll see what you need to be confident. We’re told you can run flat out for miles on end, and we have nearly 3,000 miles on a Crossfire with no issues, only improved performance and fuel economy.
You will see a difference in how crisp the throttle response is and overall performance. Very typical is a couple sled lengths and mph on top end. Fuel economy is also noticeably increased as well. Just be sure to run fresh, high-octane fuel, you know, common sense. If there are other mods, you should consider a more accurate method of tuning. This product works well on the stock fuel map and with select mods. Past that, you’re on your own unless it is based on the advice of a tested combination.
The Injector Perfector is available for $44.95 through Thunder Products (320-597-2700) and Dakota Performance (701-452-4212) and many Arctic Cat performance shops across the snowbelt.

    HAS ANYONE HAD SOME GOOD TO SAY ABOUT THESE? MILAGE ? PERFORMANCE? I BOUGHT 1 FOR MY CF, AND 1 FOR MY F7. ARE THEY SAVE TO USE? SHOULD I INSTALL THEM? THE LOCAL DEALER HAS NO COMMENT. (IMAGINE THAT)

    I have a 2005 F7 and have run the injector perfector for over two thousand miles. I also run a 2.5 degree timing key with this product. I followed the directions but opted to use the 300 main jet after reading the plug color. This year i have added the bikeman pipe mod and i still plan on using this product. I highly recommend the injector perfector!

    Does anyone know if you can use them on a M6 EFI?
