NOTICE TO OUR VALUED CUSTOMERS (Dec 2025)
I've had a few unpresidented things happen recently that has impacted my business (and customers) and I think it's important that my customers are made aware of this.
I was supposed to have total knee replacement surgery in August so that it wouldn't impact my snowmobile business. A preop appointment identified some other work I was required to have done prior to knee surgery, so surgery was pushed back to December 2nd. I trained family on processing orders using my accounting application 'Quickbooks Point of Sale' in case I was out a few days. I thought I had all scenarios covered.
The Friday before surgery my business computer's hard drive totally died. I quickly purchased another hard drive, installed it and the essential applications, and when I tried to use Quickbooks Point of Sale it required an activiation code. In a call with Quickbooks I was informed that they no longer supported it and there was no way for me to use the application. Although I had a current backup, I couldn't access it and therefore I lost all access to current orders, price lists, purchase orders, customer information...everything. On top of that I had to be out of the office for about a week following the surgery and my family did the best they could to get orders out.
Once I was able to be in the office again I implimented some other applications and processes so I could process orders through our website with ease. We are now processing orders at a much faster pace than ever before.
Unforetunately, all these changes took a lot of time to implement and then to process through a couple hundred orders in a matter of nine days. The cost was the amount of time available to answer and return phone calls, text messages and facebook messages. For those that tried to reach me and couldn't, please accept my apology and know that I'm working my way through a list of calls to return and I will get back to you. I'm now in the office every day and most evenings and processing orders quickly as they come in. The fastest way to have your order processed is by putting in an order through our website. And speaking of websites, I'm also working on finishing our new website and hoping to have it online by early January.
Thanks so much for all your business, support and understanding.

PREDATOR ENGINE PARTS
We are releasing the parts for the predator swap kit as we complete them for those looking for individual products. The first to be released is the Engine Adapter Plate and you can learn more about it and/or purchase one by clicking here. While the existing oem engine plate allows for front-to-back adjustment, this adapter plate allows for side-to-side adjustment so aligning your clutch sprocket to the rear sprocket is very easy. Positions the engine just in front of where the hood closes for clearance. Stay tuned for more swap parts soon.
Important News (Please read our important news articles for up-to-date information.)
- Snowmobile Setup Instructions - I seem to answer the same questions all the time, so I quickly put together an initial set of instructions on how to set up Kitty Cats, Polaris 120s and Arctic Cat 120s. I will take more time to refine the directions and I'll try to add photos and videos as I have time. I hope this helps everyone get a quicker start to racing.
- Yamaha Engine Performance Upgrade Kit - We now offer a performance upgrade kit for the Arctic Cat 120s with the Yamaha engine. The kit includes an upgraded performance camshaft, valve springs, gaskets, offset flywheel key, and carb jetting. This will allow your Arctic Cat with Yamaha engine to compete with all the other 120cc brands that are on the race track and backyard. (ISR LEGAL)
- Installing Valve Spring and Setting Valve Lash - Please click here to open the instructions.
- Rev-limiters - Do valve springs still make any difference?
- We are extremely disappointed in the ISR decision to implement rev-limiters. We've dealt with model difference performance since 2001 and there are other unexplored ways to resolve this issue more economically than to force every stock sled owner to spend $50 for a rev-limiter on every sled. There was also ZERO testing done on this before the 2014/15 season when these devices had to be implemented and they were not initially available for everyone until well after the season started. Our suggestion to ISR was to leave all classes the way they've been for 14+ years and just add a "rev-limiter" class for those racers who don't want to take the time to make their sleds competitive. Those wanting to race in that class could run in both classses because the rev-limiter has an on-off switch. Then the proper testing could have been accomplished without jamming this poorly planned rule change down everyone's throat. As far as valve springs go, THE VALVE SPRINGS WILL BE EVEN MORE CRITICAL. Just like the sprinter class and past chain drive classes, this will become a race to the first corner. Whoever gets to the first corner will almost always win the race. That's where the valve springs come into play. With our special ISR LEGAL valve springs, they get your engine from idle to max RPM quicker than any other valve spring on the market, thus getting you to the first corner first. Click here if you unfortunately need to purchase a rev-limiter for Arctic Cat or Polaris.
