Hi all just an update on K&N two filters ordered and meanwhile I have drilled 2 1/2 holes in the front where air is forced in to increase more air flow ( hovered bits of plastic out ) I know K& Ns are more noisy but Ryker is a noisy engine ( and I wear ear valves ) regards Nico 75 :yes:

There were many reasons for the change of the site software, the biggest was security. The age of the old software also meant no server updates for certain programs. There are many benefits to the new software, one of the biggest is the mobile functionality. Ill fix up some stuff in the coming days, we'll also try to get some of the old addons back or the data imported back into the site like the garage. To create a thread or to reply with a post is basically the same as it was in the prior software. The default style of the site is light colored, but i temporarily added a darker colored style, to change you can find a link at the bottom of the site.

Why would u do that? Im sure the engineers at BRP designed the air box to get the desired amount of air. If it isn't broke, dont fix it.

Some people are always looking to make a better mouse trap. Engineers are not the only component in a product. If they were, things would be much different. You also have marketing and finance which many times have a greater impact on the final product than do the engineers.
Not saying that drilling holes, as Nico75 has, is a good idea. But it is a myth that products should be left alone because they have been engineered to the best possible outcome.

Curious...
Looking at the parts list on cheapcycleparts.com it is a bit hard to understand where the holes were made. The ( what is called the air intake silencer) has three parts. the box, filter and cover. Over the cover is the body panel. Any hole made in the box would bypass the air filter and any hole made in the cover would be restricted by the body panel though there cold be added air flow to some degree. Was there a sound change after making the holes..? let us know the difference when the K&N's are installed....:thumbup:

Hi duke50 if you consider the K& N air filters which allow more air flow , then the more air the engine receives into air box , sucked by throttle movement improves engine response . I am fitting 2 brothers exhaust (cat removal + weight ) 17lbs lighter ie more power with less weight , more air intake = HOT RYKER. Anyway that's what I'm doing. Regards Nico 75

I'm with you. Having trouble seeing where holes would #1- Do any Good & #2- Where exactly the holes were made. Best I can determine would be in the louvered intake horn. Since this is the designed intake path, it wouldn't create a problem.

I think he wrote 2.5" holes. Not sure though because it wasn't clear.

The advantage to the K&N for engine air intake is more the much longer service interval and that they will probably last the life of the vehicle than for a performance increase. As for the CVT application. We've already had an owner who's transmission ran too hot because the air filter got clogged and was not flowing enough air to properly cool the components. Because a K&N is so much more clog resistant than the OEM paper filter, this could be a real advantage.
I’ve put K&N’s in both, I know they are the last air filters I will buy for this trike so performance increase or not I’m happy with them already. Oh and my bike has been mid mods since the filters were installed so I couldn’t tell yet if there is any performance increase. Driving it later today though!!
The restriction of the Air Flow is a function of the required volume of Air. At low RPM's even at full throttle the air flow demand or requirement is strictly the function of the RPM of the Engine. Remember, that the intake Air Requirement is created by the down stroke of the Piston, ie the amount of air required is only that required to fill that piston. Think a bucket and filling it with water then emptying it and refilling it again and again. The faster you have to do this the bigger hose or higher water pressure is required to completely fill the bucket. To imagine higher water pressure, think forced induction (Super or Turbo Charging). As higher volumes of water is required (think RPM rising) the reduction in impediment to water flow is required (think hi RPM). Its all simple physics.

This is a good site that tells the facts about air filters including K&N, this is why I won’t buy anything that has a K&N air filter on it when I’m looking at it, https://www.nicoclub.com/archives/kn-vs-oem-filter.html
It’s quite a bit of reading but is a real informative site.

If it isn't broke make it better, I also like to tinker. I bet the engineers cringe at some of the things they have to do to comply.
