Great detailed explanation of the Twin's air system! Thanks for taking the time to make these very informative videos and helping out the RE650 community. Now I just need to get some of those pods to make my bike look "cute" 🤣... think they come in orange?

Thanks for the video, when you do the pod filter mod are you also getting rid of the E vap system and if so what do you do to the hose that goes to the purge control valve thanks again for the help and the great channel 👍

Excellent. Thank you.

A friend of mine made himself a airflow test rig. After some experimentation, he found that the little pod filters were the WORST form of air filter. extremely detrimental to air flow that you could ever use. he found that the std filter was by far the best filtration. Please run comparison dyno tests if you disbelieve.

Greetings from Las Vegas! Love your videos! Do you sell all the filters needed to remove the airbox? I'm also interested in the secondary air tube. Do you ship to the US or should I look locally? Thanks!

Along with greeting them and congratulating them on their great work, I would like to know the value of this kit, the conical filters the pipes etc, everything necessary to remove the original filter, I do not seek more power, only aesthetic because I want to install this engine in a rigid chopper chassis, thank you very much and I hope to soon see more videos of your Chanel.

Hi. Great series so far. WRT the EVAP canister and its removal. Will removing the EVAP valve throw an ECU error? and do you plug the fuel tank inlet pipe nipple? Thanks

Great video! Thanks. Inside airbox there two rubber ducts to each trothle body. These ducts are made with sound reduction purpose or they are there for some performance tuning? They can be modified for some performance increase? Thanks.

Thanks for the informative video. Now I understand why the air is drawn in through the center of the filter and not the exterior as with other filter systems. It seems that this set up would make reusable air filters harder to clean. It's been bugging me since I noticed the different air induction technique.

The trick is a soft toothbrush. You put the filter cleaning solution on the inside and gently spread it with the brush. Let it soak in to break up the dirt. Then (again gently) brush the dirty inside as you rinse the solution off with warm water from the outside in.

Hi guys, great videos. How much Hp/Nm improvement could I expect with a standard 650 plus new exhaust (headers and mufflers) and air-box mods ( hi-flo filter, remove intake cover) ? Can I get away with those mods without an ECU flash or Power Commander ? Thanks. Subscribed.

Wish your shop was next door, well no...I'd be a lot poorer. I like your philosophy, straight forward honest facts, nuts and bolts approach. There a couple of things I'd like to do to my Interceptor to optimize the A/F ratio and fix what I think is the lag in the fueling at low RPMs, I've added aftermarket exhaust and removed the snorkel, DNA is next when the stock filter gets dirty, (I'm frugal :)). My problem is there is no dyno in my pace, like to discuss piggyback ECUs with you and possible maps. you do international shipping?

I would like to know how to remove the air box. Specifically does it come out the side, or was it installed with the motor from the front, or another way of stating that, what is the factory build sequence? Also what has to be removed or pushed aside to make enough clearance? Thanks, Ronn

simple block off the 2nd air to exhaust . all b/s . done motor runs cooler pipes not as hot ..done ..then run a crank case vent hose out back with a small filter .. done . .idle air hose also a small hose and small filter ..done now the motor can just burn clean air ... no oil fume crap ...you can do this with the stock air box still on it and it will run better ..did this on my 2001 triumph and its idle fine for 20 years

Will the ECU configure after the pod air filters? Or will it require a programmer? Because If the air input(air filter) and output (exhaust) are free flow but the fuel amount is same it will make the bike run more lean(hot).

Are there any benefits to removing the secondary air system? Thank you for the videos!

@RevelryCycles

3 жыл бұрын

This system is commonly referred to as "Aspirated" air injection. This achieves air injection by taking advantage of the negative pressure pulses in the exhaust system AT ENGINE IDLE. A sensitive reed valve assembly (called an aspirator valve) is bolted to the front of the engine above the exhaust ports. These are connected to the electronically controlled Secondary Air Valve via a common rail and a hose, which draws air directly from the clean side of the air filter. During engine idle, brief but periodic negative pressure pulses in the exhaust system draw air through the aspirator valve and into the exhaust stream at the cylinder head. This system has been in use since the 1970s and is relatively common on modern motorcycle engines. The primary function is to add oxygen to the exhaust when the engine is cold to help burn unburned gasses and heat up the catalytic converters. In a race engine the SAI serves no purpose. There is no "performance" benefit to eliminating it. Eliminating it only reduces complexity and can make reading Air/Fuel Ratio with a wide band sensor or sniffer more accurate at idle.

While we don't do a "kit" we do sell all the bits you need. It's just the POD filters, a breather filter, a tee for the breather line and some zip ties. You use the original breather hoses and (once the air box is out) it all just bolts on. However, removing the OE air box is not a "simple" task. One of our mechanics shot some pictures of one he did last week so we'll have "visuals" to describe the process.

You will not improve this motorcycle just by using an open filter. It’s like putting on a bigger size of shoes to improve your running speed 😊 I found the booster plug indeed helpful for throttle response and acceleration since it richens the fuel mixture, but it does not enhance power in general and it is not a must. If you can spare the money just get good sparks, regular oil change, and maybe the booster plug. That’s it. You don’t need more for this bike. I’ve ridden 10K with this thing through Europe from the Alps to highspeed roads to gravel roads. For the last few thousand miles I dialed down to stock with booster plug and it is perfectly fine 👍

Great explanation on the free-flow air filters. One thing everybody forgets to explain, though, is that it take a lot more effort to clean them than a paper filter. Check the full instructions on how to clean a free-flow filter here: kzread.info/dash/bejne/gGyL0sWOZJa5lLg.html This is probably not an issue for competition drivers because they are used to a lot of maintenance for their bikes anyway, but a street rider needs to know this. A dealer won't clean your free-flow filter for you, you need cleaning materials, oil and time to do this whenever your filter is dirty. So yes, free-flow filters have their use but if you are a rider who keeps his bike maintained at the dealer, then a free-flow filter is not for you.

Interesting opinion but wrong Pike. More airflow doesn’t equate to more dirt in your engine. The high flow filters are more efficient than stock by providing a larger surface area for air to flow through and by using oil to create a “sticky” surface for the dirt to adhere to. These filters filter down to 5 micron. We wouldn’t want more dirt in a high performance race engine.

Many of those daily riders accumulating hundreds of thousands of kms with no measurable ill effect on combustion chamber components.
