Removing AIS "elbows". Need help, thanks

Okay, so I dropped the stock pipe, pulled the AIS out, after loosening and shifting the radiator forward a bit, but now how do I get the elbows pulled out of the head? I can get a vice grip on one and rotate it a bit (within the clearance of the parts and the vice grip), but how to get the thing out? I don't have a torch handy to heat it, if that is one way to ease this task. Any suggestions from people who've done this before, or know how to do it? It's a 2000 R!, thanks.

use a squirt of WD-40 and just twist man. Your forearm will be pumped up when you get done (no pun intended) but it will eventually come right out. Just keep twisting/pulling ! after you get the first one they are easy !

Give yourself some room to work. Pull the rad. Then do as the guy above said. Lube and twist and pull. They will come right out. tom

Pull the radiator, it will make it a lot easier. I used one other trick. I found a screwdriver that fit up inside the elbows. I used that as a lever to twist the elbow back and forth as I pulled with the other hand and a pair of vise grips. It took about 20 back and forths per elbow. It was easier than doing the twisting and pulling with the vice grips alone and turned into about a 5 minute job. Good luck, let us know how it goes.

well i saw a guy that just plugged the elbows instead. I wanted to know where he got the plugs. I dont want to have to make threads in the head of the motor, i think the plugs will be easier. Can any of you ugys help me out? Thanks David

I sourced plugs from Graves that replace the elbows. $20.00 for 4 plugs. Pull the elbows and tap these plugs into the head with a small hammer and brass drift. No need to thread anything. tom

Thanks, guys, I was out working on the bike, and figuerd it out. Basically, what you all have said. I used a screw driver that fit inside the elbow, and kept twisting and pulling to get them out. throttle-cntrl, you weren't joking about the forearm pump. I feel like frickin Popeye over here, thanks guys! :)

Can I just plug the end of the hose that goes to air box? That's what I was going to do. Or do I have to do what eyespy did?

The Graves AIS plugs are in the head now, in place of the AIS. Cleans up the front of the motor quite a bit. Glad to get all that extra crap off of there. There are two rubber hoses to the AIS, a small one and a large one. Do these just get clamped off now? Thanks.

call me an idiot, but what is an ais, and should i have removed mine when i put on a full system? thanks in advance

It's part of the emissions systems, introduces fresh air into the exhaust pipes. You can get alot of popping on decel with it using a full system, and if you get this, you can get rid of all or most of it by removing the AIS.

Plug the airbox with a rubber cap. The little one you could do the same to but it goes back tight under there... so you could just clamp that one closed. No biggie.

They are on the far left-hand side. Originally posted by throttle-cntrl The larger hose gets removed. It goes back to the airbox. Plug the airbox with a rubber cap.

The smaller of the two hoses is the vacuum source for the ais to function. It plugs into the head near cyl. #1. If you have synced your carbs, this is the hose you pull to connect the sync. tool. I used a vacuum plug and removed the hose. If you are just going to plug the line, do it right or you will have a vacuum leak. tom

Okay- now why are you guys confusing me and making me worry that I missed a hose when I removed mine months ago. :confused: I remember removing the 4 hoses at the elbows and capping the elbows and I remember removing the large hose that ran to the airbox and plugging the air box hole, but for the life of me I do not know what smaller hose you guys are speaking of that goes to the head near cyl #1. I even looked in the service manual to try and figure out the hose and do not see it listed there. Help- I don't want to have a hose there that should be sealed. :confused: Here is a page from the manual and I just don't see it: Some put me straight :) Larry

I can only tell you what I did to my bike . It is a 2001. I think, but am not sure, that the 2002 and later models use a different set-up to accuate the ais. Maybe the guys with newer models can fill you in better. Sorry. tom After looking at the picture you posted, your set-up looks different than mine. My old computer didn't display your picture at first.

Hey Tom, I should of checked your model year as that makes sence that the 02' would be diffrent. I didn't see another smaller second hose in Big Daddys pic above either so thanks for following up and putting my fears to rest. Larry

The earlier years are set up different. Here's a pic from '00/'01. The smaller hose would be #18: http://www.onlinemicrofiche.com/OEM_Images/yam_mc_images/00YZFR1MB6.gif

Ahhhhhh, now the turth be known that its the 'older model syndrome rearing its ugly head' is the culprit. :p ;) BD

best quickest and least effort way i have found to remove those elbows is to grab them with pliars as mentioned and while working them side to side in your other hand use a lond screwdriver or pry bar and pry on the bottom of them. The last four I did came out in under 4 minutes. The twist and pull method works, but you will be worn out by the time the 4th ones comes out...lol
