My Impressions:

Pros:

Tech: With porting & bored carbs I can make 176 hp on pump gas & 186 hp on race gas.

Fits like factory pieces.

Ceramic coating looks and works great.

Noise levels are almost the same as stock decibels.

Best bang for my buck, with the best horse power gains.

You can change the Trail Domes to Hi Compression Domes for more hp if needed.

Cons:

None

Bottom Line:

When I decided to build my sled I checked around and found that Rich Daly of Dyno Port was getting some really good horse power numbers out of relatively stock sled engines. This motivated me to ask Rich the Mad scientist to help me with my project build. I like the way you can set down and chat with Rich and he gives you the straight skinny on how to make your engine run better. I followed his advice and gathered up the parts needed to transform my sled in to as close as possible to his hill climb sled. I am getting roughly 163 crank horse power with the way my sleds engine is set up right now, and I can't see anything wrong with those numbers. The build went smoothly and all his parts fit perfectly.

Rich also supplied me with the Chuckaroo Trail Head, so if you want the skinny on this head, you need to give Rich a call. Dave Rock from U.P. Cycle & Sport of Iron Mountain worked with me to change over the stock parts from the oem head and install them on the Chuckaroo head. We had to use a little "goop" to seal the water coolant plate at the bottom of the head, and also shorten some bolts up to fit properly. The reason we had to goop the retainer plate is because the Chuckaroo head does not have a o-ring like the oem head. After running the motor there were no leaks, so this is not an issue. The knock sensor and the carb coolant connector went together with out a hitch.

Why did I choose Ceramic Coated Pipes over the Standard Black painted Pipes? I chose the ceramic coated pipes for their looks and performance gains over stock components.

The benefit of the ceramic is that it will hold heat in your pipe longer keeping more crisper throttle response, with less bogging and better acceleration.

Remember that a hot pipe is a happy pipe, and your sled will be running at optimum performance. Installing the y-pipe, expansion pipe, and the canister was a breeze and they went together just as easy as installing oem parts.

While I was at it Rich convinced me that me being Canadian, and I drive like one too, he suggested that we shim the needles and go up a couple of sizes on the jets. This is an effort in patience to remove the carbs and to install these items, but with patience you can acomplish a lot. I had to remove the carbs anyway because we were also installing V-Force 3 reeds, which absolutely make this machine rock!

Most of the work that I done could be done in your garage at home if you have the competence and the proper tools. I would suggest getting a good mechanic to install your head. This is something that you need to do right, and do it right the first time, or you have wasted a bunch of money if you warp your head. Jetting the carbs and shimming the needles is something we do on the atv's all the time, but the same goes for doing this too. If you are not familiar with this type of work seek help from your authorized mechanic. The sled was running a little lean stock, so this should fatten the carbs up some, and give me some peace of mind on long wide open runs across the lake.

I took my time doing the work on this sled because we do not have snow yet and I was in no hurry to make any mistakes. The build went off the way we had planned and on initial start up, everything worked great. The motor sounds just like any stock machine and I am biting at the bit to hit the trails. I have added purple ice to my coolant system, and with the larger coolant area of the Chuckaroo heads I am very impressed at how cool my engine runs. When I started it up I left it run in my driveway for 5 minutes and the temperature was about 50 degrees Fahrenheit that day. The highest the temperature gauge read then was 4 bars, and I can tell you I was impressed.

So, the bottom line is, if you want good reliable trail horsepower, then you need to give the Mad Scientist, Rich Daly a call and see what he recommends for your sled. You will be glad you did, I know I am, Thanks Rich!
