I downloaded and printed the Jason Mod articles and pictures along with the Blocking off the AIS article and pictures. I am going to do both of these mods. My question is, once you do the AIS blocking and then go onto the Jason mod; what do you do with the vacuum hoses from cylinders 2 and 3 once you have spliced in the small 3/16" fuel tubing as shown in the pictures? Thanking you in advance. Chris -
My bike was backfiring on deceleration way too much and with the 4-2-4 nasty boys installed was worse and louder, after reading the simple instructions of this website plugged the AIS and voila what a difference !!!!!!!!!! I still have some but improved about 80% I will need to synchronize my carburetors but before I buy anything I will try to see how is done just want to say thanks to the group the info here is priceless !

Well, I got off my butt and put the bike on the lift yesterday. Put the stock leveling links back on, tightened up the neck bearing. That took a half turn to snug it up! Then I went ahead and pulled the fairing loose and pushed the forks up 3/4". Plugged the ais system. Took it for a quick ride yesterday and a 55 mile ride into work this morning. So far, Very happy with the saddle height. I can touch flat footed sitting on the bike and have my knees bent. When I stand up I have about an 1 1/2" clearance. Me likey. The bike haandles much better at low and high speeds. Seems like I can turn a tighter radius. Me likey that too. AIS plugged. I know some are against it, but for $1.28 for the 2 rubber stoppers and the 15 minutes it took I figured why not. Pretty much eliminated the popping through the exhaust. I run 29" Samson turnouts. It may even be a tad quieter without those gases burning in the pipes, I could be wrong though, but could just be because it does'nt pop like it used too. I do have a small exhaust leak and need a new doughnut gasket. Once I replace those, I do not think I will get any popping at all. Me likey likey.

I am new to this site and have really enjoyed reading all of the tech tips from a vast variety of owners. I'm particularly interested in plugging / removing the AIS on my 2001 Venture. I have read several of the post and was looking for anyone who has done it more recent. Any recent updated tips would be greatly appreciated. I look forward to hearing from anyone!!! Thanks, Jakbag

What function does the AIS provide?

HELP!!!! you dont know how luckly we are to 1st ride a RSTD and to have a site like this, with people who will help you with yr situations. (well almost anything). I have a 06 RSTD 82k the AIS has oil leaking from around the the AIS Box?? Help????? what can I do to fix the situation. I have never removed it . But need to be cleaned and stop the oil. thanks,, -
I have removed the AIS system from my 2006 RSTD. I crimped the tubes and that shut off the nipples from the heads. How can I plug these tubes if I remove the original pipes/packing/clamps?
-
I have not been a member very long and haven't posted at all but I wanted tell all that the information from this site is plain amazing. I have an 07 RSTD and have added a few items that this site has made real easy. I have a little problem that I can't trace down. I get a exaust gas ignition on deceleration every once in a while. The bike starts and runs great but when I let go of the clutch on a down shift it poofs once and that is it. Annoying more than anything. Anybody have a thought? My guess is that the AIS valve is not closing or is a little sticky. Please don't suggest to bypass the AIS as I do care about the environment. I also lost my full time job last August but have been blessed to work contract jobs so I am doing well. My next job will take a year to complete and it is in Texas. Won't be able to take the scoot so I am heading out for one last adventure until I have to go. Agian Thanks to all

Could anyone please tell me what size of dowel or plug is required to block off the AIS systems? I have read the articles but not sure what size plug is required. Thank you in advance Chris

I was doing some maintenance before going on a three day trip with our local Star group so while I was at it I blocked off the AIS with rubber plugs. I was hoping that the popping would be gone. It's the same as it was before. I guess I need to check for an exhaust leak. Will synchronizing the carbs help? Any other suggestions would be appreciated. Thanks

My carbtune finally arrived. The bike still has the AIS. After removing the 4 vacuum plugs, do you have to plug the 2 AIS lines while synching? Thanks

Didn't have anything quite wide enough to plug the AIS, so I got the biggest tapered wire nut I had in the workshop, wrapped the outside of it a few times with duct tape to make it snug in the hole, and then duct taped over the plug after insertion before reattaching the hose. Works like a charm! Didn't do the front AIS yet, but I'll use the same thing when I do my next oil and filter change and can get to it easier. Go me! -
I was googling something else and came accross this article. I don't know anything about AIS, but with everyone talking about the RSV chirping, I thought this might be interesting... AIS, What's chirping? Written by StarMyram, on 06-22-2006 19:16 I used to have an 04 V-Star 650 Classic and it made a funny noise while coasting on highway and cruising in town at low rpm. Just got a brand new 05 Roadstar Silverado ...Ya know, this bike is beautiful, torquey, and a nice low "bump,bump,bump" exhaust tone at low rpm. But for crying out loud, WHAT is this annoying chirpy sound?! This bike has it even worse than the V-star! Well, the other night I was fumbling around the running engine with my fingers and eneded up with my finger in the air intake tube hanging down off the AIS pump. The chirping stopped! HA! Found thee source of the noise! Did some research as to where these little pipes went to and fro on the AIS. I decided I could do without the peice of crap on my bike. (don't tell Kyoto! ) I got out my tools and removed the AIS pump and it's filter and all the brackets. Removed the vaccuum pulse line from the intake manifold and put a cap on the tee. I left the chrome tubes attatched to the heads, I used the one left over hose (pushed a 1" long wooden dowel into the hose to seal it off to avoid exhaust gas travelling from one cylinder port to the other through the chrome lines and burning up the hose) and installed the hose to each chrome line. After admiring the new clean, uncluttered look of the front of the engine without AIS, I started the engine and admired the clean V-twin engine sound, with a nice clean exhaust tone with no "fluffing" from the tailpipes (the way it should be.) I took the bike for a ride and Voila! No more chirping sound! Yeah Baby! I understand Californians have emmission laws and lots more tubing on the bikes for charcoal canisters and such so I don't know about thse bikes. Removal of the AIS system is not necessary for performance gains since the AIS does not rob power or performance. But it's just plain ugly to look at, and it annoyed me to no end because of the crappy sound it adds to the engine. Here in Alberta, I can get rid of it without some emmissions police hassling me too. I plan to make steel plates to cover the ports in the heads and remove the chrome tubes completely when I get time this coming winter.

My friend has a 1100 vstar and is looking into blocking off the AIS. It has Cobra exhaust on it but nothing else has been done to it. He says it cracks and pops which I would guess may be common when changing to aftermarket exhaust with less back pressure. Is anyone familiar on the procedure to block the AIS off ? Thanks

Folks are talking about pluging the AIS to cure popping on decel. What and where is it? Thanks

Come and listen to my story about a man named Jed . . . no, wait, wrong story . . .sorry (and appologies to Flatt - or maybe Scruggs). This story is about how glad I am that I have a functioning AIS system on my RSV. My bike has been running perfectly, no popping or anything else odd, but when I had it all torn down last Saturday to check the valves, I thought it was a perfect time to go ahead and replace the plugs anyway. It was a little early for me with only about 15,000 miles on them, but I had the old ones out, so why not? Well, on the 200+ mile ride home from Tom's place, I was getting a lot of loud popping and bangs rolling through the small towns. Bummer! You can probably imagine how disappointed this made me - here I had just done major work on the bike and put in new plugs and all - I expected to be getting about 150 miles to the gallon and roll through town to cheering crowds! But alas, instead of basking in the adoration of pretty women and admiration from all the wannabe bikers, I found myself having to hide my face in shame. Now the odd thing is, I didn't notice anything else wrong with the bike - gas mileage might have been down just a tad, but considering the 105 degree heat and high speeds I was running, it wasn't really lower than normal. And I had zero problems hitting an indicated 100 MPH passing a couple of long strings of cars, so all four jugs had to be hitting OK, right? But there is no denying the evidence - popping from the exhaust on these bikes absolutely proves something is wrong with the way the fuel is burning. So today I finally drug my rear out to the garage to check things out. I fired the bike up and began checking how fast the header pipes were heating up with my fingertips, and it was obvious that the RF (#4) pipe was different. The other three were too hot to keep my finger on for more than a second or two within 15 seconds of starting the bike, but not #4. It was fairly warm, but not burning. Even tho these were brand new plugs, I pulled it and put an old one in - problem solved! And THAT's why I am so tickled my AIS is working - without the warning signs from the exhaust popping, I would have almost certainly ridden the bike with that bad plug in there for 20,000 miles or so before I accidentally fixed it during the next major service. The interesting thing is that this was the EXACT same symptom Ponch had with his bike up at Don's maintenance day - same cylinder, same symptoms, same fix. And his only real indication that something was wrong was the popping when he tried to reconect his AIS system! Goose

I have a question for those who have totally removed the AIS system on their RSV....after removing the valve by the rear shock, did you also remove the box or valve that is at the front of the engine by the oil filter? If so, I'm assuming that is a remove the radiator job too? Thanks, Joe -
I have an 06' RSTD with K & N air filters and BUB slip-ons. The bike runs great, but on deceleration it spits and sputters (back-fires) a lot. Will removal of the AIS stop this or help at all? Thanks, David

Hello all, I just installed a set of Baron's bag slash pipes (and ah yeah, they are loud...) and plugged the AIS. I removed the front and rear AIS hoses and used a 3/4" and (3) 11/16" plugs to stopper up the mechanical parts as well as the hoses and yet I'm still getting a heck of a lot of popping on decel. I don't think it's any better than it was before I put the plugs in and I know no air can get by those plugs - they are shoved in there tight. One of the guys in our ride group has the same mufflers and had to rejet and I know just about everyone has had to say you don't have to but maybe there is just something different on the '06 and later bikes that needs to be specially tweaked? Any help appreciated, gp

While working on the bike the other day, I noticed that the reubber manifolds from the carbs and showing some signs of cracking. Bike is an 01 and has 55k on her. Is this comon? I don't notice any problems, have some slight backfiring, (have not plugged AIS yet). but the bike getrs consistant mileage, 35+. Is it expensive/difficult to replace the manifolds?
-
:confused24:Thought I would be getting better gas mileage after Roadhouse pipes and K&N filters(36 mpg). I plugged AIS correctley and bike seems to be running fine. (38 mpg) before pipes and filters and AIS plugging, only 960 miles on bike ??? Maybe need to rejet later ???? Got upwards of the 40 mpg today:cool10: My bike runs wonderful. Syncing the carbs did the trick. Will check mpg several times to get exact reading later.Thanks everyone for your help. -
Does anyone know what size bubber stoppers to use when plugging the AIS? I wanted to go ahead and buy them now so I'll have them when I change the oil.

Last week I installed Baron's 4-2-4 slip-ons on my 2006 Midnight Venture. Also put in new plugs; plugged the AIS lines and the inlet to the AIS pump; re-synched the carbs;and put in new air filters and a new fuel filter. The bike is now popping/backfiring during throttle up/throttle down and even when holding the throttle steady at 60 mph. Have I missed something? Can anyone help/advise with this annoying situation? Regards..........Boomer

Hey Beer......I have my exhausts installed!! They are good uns!! My remaining Chirp is fully cured!! I received the brackets yesterday and late last night installed them. Do you know you can set off a car alarm with them lol!! I revved them up in the garage and the alarm went off in my jeep! It was dark and cold so I only rode the bike about five miles to check them out.......so far no noticeable difference in the bikes performance and there is a small pop from the AIS......will have to take them for a ride and down shift in a hard turn to see if this is going to require plugging the AIS. Hey you better get a wireless radio headset if you like music lol! I love them myself, has cured my chirp!! Kit

Ok...I'm fairly new to working on a bike and I am trying to learn all I can. In this learning experience I heard that the AIS can cause popping and backfiring, which I have. Initally I disregarded it as I planned on plugging it. But after a little further inspection I have noticed that it only occurs on the right side (at least when on the side stand). I found this out by reving the engine and letting off quickly, which in turn causes the backfire, and as soon as I let off, I glance at the pipes to see which one it is occuring with. With that said, would it still be the AIS (as I haven't plugged it yet) or could I have a leak somewhere on the right side. Bear in mind, I haven't put it on a jack to level it yet, I am just fishing for what to possibly look for. And for a little history on the bike, from my understanding it had sat for quite a while when it was trying to be sold and I am not to sure how ofter it was ran during that time. I know not enough for the battery because it was bad. But it does have a fresh tank of gas...
