This technique is AWESOME. Removed system from my 2002 Classic this morning. Take your time, have some patience, and overcome your reluctance to bang away on your bike with a hammer and file, and voila, it's all done in less than 1/2 hour. My AIS was cracked, so the weird sound is now gone. Much better than removing all the parts and pulling frozen pieces with pliers. If Byrds music is half as good as his ingenuity on bike modifications, I should be hearing him on the radio!
working on mine right now and found these connectors also swivel out if you are patient enough. the system so called pump is not really even a pump just a vapor valve. just removed it all. I also re installed the clutch cable bracket but cut off any references to the pipes and applied silver paint to the edges. looks great when its all off.....
By removing the system it resolved the backfire bug I had, my star has cobra pipes and a maximum k&n air kit so this was a must… you can also remove that pump if desired.. cool video, 👍
THANKS FOR THE TIPPED ON HOW TO REMOVE THE AIS PIPES , HOW ABOUT THE WIRES CONNECTING TO THE BIKE AND THE PUMP , SHOULD I REMOVE THE PUMP AND ITS ATTACHMENTS AS WELL?
I just did it on my bike. I had no problems except for one of my tubes rusted out and was blowing exhaust at the lowest side of the tube. So i did it just to get rid of it. I did my a bit different but basically the same concept.
I have a 2007 which I pulled the stock baffles off, I am making the exhaust come out in a “true dual” way. So one pipe a side by just flipping the rear cylinder elbow! Anyways any word on reviews with my year ? I’m wanting to give this a shot because I have an issue with the popping myself which I’ve had 2 shops saying that the popping will happen no matter what I do?
Did this today on my BT1100 (same engine) Because we are not allowed to have guns, a bullet casing was a bit hard to find. So what i did was grind the plugs down, and welded them shut. Then i hammered them back in. 10 minute job max. Don't forget to plug of the airfilterbox.
@@Byrds1967 It is still on the lift, Gonna rejet is also. Here in the netherlands they came with a little restrictor in the carbs, so im gonna get those out and rejet it. Also gonna get a k&n filter. It has some carbon exhausts and i think the previous owner did not do a rejet.
also a fired 45 round is a perrrrfect fit.....awesome. amazon wants 20.00 for those machined tapered plugs on this application, I think I saved some money....
What I did on my 94 Virago 1100 was just remove the tubing and then hammer 9mm shells into the knuckle instead of hammering the knuckles out and hammering 45 shells into the head. Works just fine. If you ever want to remove them I think you could probably get them out with a drill. I used a 16 penny nail head to tap them in deep.
At 5:50 you can see how you are damaging the fin in the cylinder. I would be a little more cognizant of that if working on a customers bike, but nice job over all.
My next project. Added some cobra pipes, and she's now too rich. The cackles are nice, but the backfires when decelerating can be fairly loud. Also I did not have to re-jet my 1100 for the cobra pipes. I should have, but they have an outer cover that would hide any blueing. But is that normal? To throw a aftermarket exhaust system on a completely stock bike, and burn rich?
Freeking awesome man, thanks for the video .... I will have to do that to my 2008 V-star 1100. I really love the sound of your bike. I just pulled out the baffles in my OEM pipes, but I like the sound of yours better. I will be jetting the carbs myself this winter and if I may ask, what are you using for pipes? How did you get that sound?
What do you do with the line that runs down and into the pump? I’ve seen guys plug it with a golf tee but wouldn’t that fill up with gas? What’s the best to do here? Can it be removed? If so, do you need to pull the tank? TIA! 👍🏼
Did this to my 2002 V-Star Classic and it backfires BADLY!!! But it is a used bike and someone knocked out the baffles from the exhaust pipes, do you think that is the reason for the backfiring?
You can remove the air pump if you want. You then might have to terminate some electrical lines to it. It's just more easy to do it the way shown for most riders who want to simply bypass it.
It recycles unburnt fuel back into the cylinder to reburn it. It's more for EPA concerns. Folks get rid of the system to: 1) Give their bike a cleaner look. and 2) Get rid of the vacuum draw on the cylinders.
Hi made the mod and couldn’t have been easier. No more backfire or pops from the removal of stock baffles. Could you do an update with suggestions for the actual pump decommission or removal? I see you left all 3 hoses (two large and one vacuum style) disconnected.
The pump isn't running anything anymore. In my case I'm just leaving it in there. It looks like a person would have to remove a lot of parts to get to it.
@@Byrds1967 So when you left the air pump did you leave hoses in the by-pass mode like in your video or hook them like they are susposed to be . just a question i havnt completed the removal of the hoses yet but damn sure will
@@davidparker8662 Honestly I probably left the air pump looped into itself. I left the air pump on the bike too. Those things are tucked away and hidden as it is. The main mission was to seal the cylinders (with 45 shells) and remove the extra tubing.
The Yamaha 1100 V -Star never was Fuel Injection 💉 always used a Carburetor I just purchased a gently used 2005 V-Star 1100 it was fitted with a custom seat , Cobra exhaust, cup holder, and an oils relocation kit She purrs like a Kitten 😸
Si has cambiado el mofle por tubos directos (cobras o vance hines) te ayuda a eliminar las explosiones esto por supuesto si tambien has cambiado el sistema de filtro de aire , el motor de las vstar puede entregar como 20 HP adicionales con cambiar el mofle el sistema de filtro de aire a uno mas directo y con esto evitas las explosiones
Yeah, you can leave the chrome tubing if you want. Once you bend the AIS system tube into itself, the system no longer works. And my V-Star started popping after I put straight pipes on it. I don't think that has anything to do with the AIS system.
@@CindyDC So if your Vance & Hines installer put on straight pipes and a bigger air intake system then they should have redone the jets as well. My bike pops all the time on deceleration. The increased power is worth the pops.
You have probably figured it out by now, but essentially it was a requirement for the stock exhaust. If you do any kind of aftermarket exhaust or drill out your baffles you will "probably" needed to disable the AIS because you will more then likely be running too rich and your exhaust will be back firing or popping.
@PauseDenied Oh damn so thats where the small back fires are coming from? I have 4.5 inch cobra exhausts and the the popping has been really bugging me. I even did a valve adjustment and was all "I guess its just how the bike is".
@@justanotheropossumchannel5304 hey man - just wondering if you did this and whether it helped? Just bought a 2004 with aftermarket pipes and have some loud decel pop. Also getting high vibration at 70mph for some reason (engine related as it goes when I pull in the clutch). Gonna try this and also sync the carbs 👍🏼
Nice I am gonna do that to my 2009 custom get rid of those damn tubes, but the guy who said that you can't get hand guns in canada is wrong you can get them no problem with the right paper work.
Well a stock bike has average power and good gas mileage. Most folks get: 1) Straight pipes, 2) Max Air Filter Relocation Kit, and 3) Remove AIS System. Doing those 3 things will increase your power 20%......but you will lose gas mileage.
Please forgive my ignorance, I just bought a 2000 xvs1100. After searching google I found your video. Maybe unrelated, but I am having an issue with the oil light staying on and the oil level is just fine! It came on yesterday after hitting a pot-hole, and although there is no visible damage and the bike and runs fine, the freaking light comes on after a couple of minutes and stays on. Anyone experienced this issue? Also, Why remove the AIS?
The only time my oil light ever came on was when I had really old oil in it and had exceeded 4500 miles before a change, otherwise mine has never come on. As for the AIS....if you plan on putting on straight pipes and a better air filter system then disabling the AIS is the icing on the cake. You'll squeeze every ounce of power that bike has to offer.
If the oil pressure sensor is not gummed up like Cyrus said then it may be going out OR you can check the connection of the wire at the sensor. I've had an issue like this with my neutral safety switch and it was a loose connection.
I don't see why one just wouldn't take the AIS hoses from the cylinder heads and just use a rubber cap with a hose clamp similar to what you have on the right side of the carburetor where you connect your manometer. If you hammer on that rear (or front) cylinder AIS connector the way it's shown here, you risk binding it on the way out and possibly deform the hole. I always like to be able to reverse anything I do, and that might make it impossible.
Devin Canard I think the only difference on the classic is some exterior hardware like bigger head light, and longer fenders. The engine and AIS system should be exactly the same.
.45 colt ACP i wish i could have got these instead of the black plugs i have. damn...if only we could have handguns in canada it would be perfect here nice bike...
not sure where you got that info from. i live in canada and own several handguns and chambered in .45ACP .. simple course for an RPAL and you are good to go.
I had a 1983 Virago 750 at one time but didn't mess with the AIS system on that particular bike, it had enough power . If it's put together like the Vstar then the directions should work. Just make sure you "run the pump into itself and the cylinders into themselves" with the rubber hoses for a test ride first. If you like the change then plug them.
Interesting, but... i have v-star 1100 2005 (from Mount Rainer national park) imported to Russia. Installed V&H pipes (in USA), no more modifications.... and - no "shots" in exhaust! AIS is still on the bike. Some more of chome pipes on bike :P
The real fix for popping or backfiring on deceleration is to have your carbs cleaned and tuned properly. It will also prevent you from beating the hell out of your ride.
I did the hose swap as a test run and it did absolutely nothing positive for my 05 v star 1100. Ran like it wasn't too happy to the point of me thinking this was a prank video
Byrds1967 I just purchased it recently but it appears that the previous owner has chopped and gutted the stock pipes. I'm assuming he jetted it as well because it's not running poorly.
Generally these bikes are made to 'reburn" unused gas through the AIS system as not to allow harmful emissions into the atmosphere. When you put on straight pipes or mess with air intake then the AIS system will backfire a lot as the unused gas explodes in the pipes. Just poking holes in the muffler may not change much (if that's what he did). You can increase horsepower at least 15% if you do stuff correctly. Disabling he AIS system is just the icing on the cake....after all that. And yes, jetting the carbs (both of them) is the key after all mods are made.
Byrds1967 Thank you for the tips. It still seemed to backfire a fair amount and after a little while, it seemed to start falling on it's face a bit. I'm thinking I might need to adjust these carbs a bit.
Are you running straight pipes and modified air filter? The AIS was the last thing I did to pull the last bit of power from the bike. Mine backfires on deceleration, but it's worth the trade off.
@@Byrds1967 They are cobra straight pipes carbs been rejetted stock air intake. runs great but hate the chirping through exhaust. I think they gave me the wrong size plugs from pacific coast. I think they are supposed to fill the whole hole. seems like plugs are too short.
Now I got to think of a way to get the plug kit out and put in the new ones I bought from baron customs. They look like they are longer to fill the whole tube insert. That way there is no open space inside the cylinder to make the chirping sound go away.
@@denoc817 I went ahead and put the 45shells in the holes made chirping sounds still but are starting to fade the more I ride. There is no air leak anywhere I made sure
I removed it mainly to clean up the look of the bike. The AIS system recycles unspent fumes back into the cylinders for EPA reasons. It really has no bearing on how the bike runs.
For mine it stopped back firing. With the AIS system it would cycle through un-burnt fuel back into the cylinders and would backfire a lot on deceleration.
As long as it's carbureted it probably has one that can be removed. Fuel injected you can't. Just follow the silver tubes to the cylinders and see where it all goes.
Hay Bro. I have a 03 1100. I closed all the tubes off awhile back. cause it was the (reed valve) that went out. All this bad crap was running out. I toke it off. So now what do you do with the vacuum line. The guy at the shop plugged it. I did have it in my tool box with a fuel filter on it to keep dirt out. but sense he plugged it now I get oil coming out the carb. what's your option.
Please know that I have never used foul language in a RU-vid.com comment. To do so is entirely out of character for me, but.... 1.) What the fuck is an AIS system? 2.) Why the fuck would I want to beat on my bike and take the damned thing out?
The AIS as designed serves a useful. It allows these bikes to operate in states that have stricter emission standards. But it also helps to reduce carbon pollution. Removing/altering the AIS is selfishly irresponsible.
GE Clay It’s muppets like you that are the reason we have emission laws. The clean air and water act was passed by republicans under the Nixon administration. So much for your libtard comment. Modern cars and motorcycles have pretty good power as well as being fuel efficient and cleaner. My hat’s off to the engineers that make it work.
