2005 Arctic Cat Firecat

What was your intended objective when you started the build?

My objective when I started the build was to create a sled that was as good as or better in everyway than a stock sled.

What motivated you to start your project?

I had been running the sled with an 900 kit on it and on the last trip of the season I blew it up. Seeing as I wanted a bigger engine, I had to choose between buying a new Crossfire 1000 or refitting my Firecat with a 1000cc engine. I loved my Retro Firecat , so I decided that a rebuild would be a fun project and give me a one of a kind sled.

What was the most unique and creative thing you did to the sled?

The most unique and creative thing about this sled is that it is the only 1000cc transplant into a “diamond drive” firecat that I have ever heard of and definitely the only one in my part of the country.

What are you most proud of?

I’m proud of the fit and finish that I achieved and also the performance and reliability of the sled. I put 6000 miles after the build with no problems or repairs except for the addition of one exhaust spring after the first 4 day trip on the trails.

What do other people say about your snowmobile?

People have said that the installation looked better than stock. When I was at Dynotech getting the sled dialed in Jim said that it was the cleanest and neatest install that he had seen, which meant a lot to me.

    Awesome job. Very fast!!

  • Ross Whitney says:

    Definitely a clean engine swap and reliably fast sled.
    Feels good to brag up my Dad on this one. He really knows how to dial a sled in for the perfect balance of clutching, traction, weight transfer, and horsepower!

  • Scott says:

    A lot of hours put into this build with fantastic results. Clean and fast. I doubt there is any stock sled built today that would match it for speed and quickness down the track and yet a reliable trail sled. Great job!

  • Bev Spicer says:

    This was a great job done on this machine, it was reliable, and a great trail sled. I had a chance to drive it, and it is the fasted 2 stroke trail sled that I ever drove. this thing should have been outlawed when it came to buddy racing.
    Greg you should be proud of this build.

  • Jeff W says:

    Seen this build on the way through it’s course. My big brother is very particular, precise and very hard to beat. What better name then predator, it really suits it. Good job Greg you should be proud of it!😀

  • Kyle Brydon says:

    Stunning! A true beast deserving of her name!

  • Terry G. Lutz says:

    What can I say? Have you ever taken a knife to a gun fight? I have seen this Predator race from day one. Greg used this as a every day trail sled , go anywhere. But pull up beside him at with your trail sled and see what happens. This sled looks great and is like a rocket on rails.
