Performance Damper for ski lift

[Murse]

Honda designed a small weight in the trunk of the 1998-2002 Honda Accord that stopped a sound frequency from making the driver tired on long rides. The Lexus LFA Exhaust was tuned at Yamaha Music Corp. to make the perfect exhaust sound. I am sure there are 100's of these to list. I would definitely give this damper a try.

Just for the sake of keeping this thread going, ill bite.
the things i remember hearing when this was introduced to the public was that yamaha was giving people some of their technology to look at. In chris reids posts he clearly states.
It may never make it into a production sled. They want people to talk about it. And maybe the release a few to the public. I mean, they already use it on other product lines and within the auto industry. Its not like 500 million was spent to develop it for sleds. They saw a practical application for use within another market and are giving it a little feeler.
Absolutely nothing i read from anyone inside yamaha said this was coming so get ready.
At least not at this point.

Second. Im not exactly sure how anyone can or cant determine what any sled or manufacturer needs when the product we are discussing has never been applied to a snowmobile until now.
That said im pretty sure most of us have never even had the opportunity to do a side by side trial of this product in any application. So, comments good or bad are simply uneducated opinion. Mine included.

Hummm it looks like ken block uses them.
That just seems silly for such a well known racer to invest in a product that doesn't work. Lol

Im gonna be real curious to see how this whole performance damper thing pans out.
Im betting it will be just like power steering. The people with it love it and everyone that has never even tried it will be standing around screaming it just adds weight and there is no need for it. Lol

That there about sums it up.....

Hey smokingcrater I did not say that

Fixed! yeah not sure what happened there.

But keeping on track, another point think of how much engine vibration is discussed when it comes to these machines. I know I have turned away from purchasing certain sleds due to a paint mixer under the hood. In talking about the dampeners why wouldn't lower chassis vibration allow you not to go faster as Chris said due to the chassis feeling that much smoother. Proven time and again that excessive vibration can be very tiring during a ride/race.

With this said it does seem a bit of a band-aid fix but who knows did we ever think an R1 motorcycle engine would fit into a snowmachine and make for a really fun sled?????

Excessive vibration is a symptom of something else .... a well balanced engine will be smooth ... to be honest, vibration was the very least of the issues with the Nytro or most any other Yamaha products I had to date. Its difficult to balance the harmonics at all frequencies as any small additions of mass can increase or lower the threshold at which the vibration is induced to the point of becoming noticeable / problematic. From a marine side, practically everything is soft mounted in order to reduce the vibration transmitted into the surrounding structure. Engines, bearings, shafting and event thrust mounts are isolated using suitable designs and materials. However there will still be instances - loading / RPM combinations that correspond to the natural frequency of the surrounding structure ... railings or light shades may begin to vibrate .... change the loading / RPM of the engines and the vibration ceases or moves to a higher frequency ....

Some of the vibrations - i.e. track drone are likely very difficult to establish give the infinite range of conditions experienced - tension, shock settings, amount of snow on the rails, type of snow, slider condition, and so on yet for me that has never been a major issue - tunnel icing on the other hand is significant and why Yamaha hasn't accepted and addressed that major flaw is boggling!

Personally, I hope they come out with something worthy of discussion and purchase in the near future because as the $ of sleds goes up, the purchase frequency will go down! Just bought two new sleds so I likely will not be in the market for a few more years. For those that don't visit some of the other sections, check out the chassis that one of the after market manufacturers is offering!

PHC makes some amazing sleds no doubt. I wish a non-mountain company had developed a long travel light weight chassis for my Apex motor, would still be riding it!!

Thanks Just giving you the "stink eye"
