I had to install a new idle screw/cable and saw this:  I also have a new front isolator/mount... should I install it and keep the old one for backup? (I bought it cuz I was getting some wierd vibs but not sure what its from ... the existing looks ok to me) | ||

oops... the little metal one at 12 oclock, above the intake. There is no connection for it. | ||
| Wolfridgerider |
if I'm not mistaken... that should have a little cap on it.... and I would say yours is missing because it backfired thru the intake and blew it off. whats it for... to hold the little cap that is missing... best I can tell. Other than that, ya got me. | ||

I believe that is unused and should be plugged. The stock plug has a bad habit of drying out, cracking and falling off. I would suggest anyone who takes things apart this far to replace the plug with a more durable plug before it causes you grief. | ||

Something like $.07 at the local napa. I carry a spare with me.  | ||

What are the bad vibes? When my Front Isolator went bad I got really bad vibes under deceleration, especially around 2.5 - 3K rpm. I wouldn't bother changing it unless you need to, but it's easy to do. | ||

At 12 or 3 o'clock? I don't see anything at 12. | ||

sitting on the bike, it would be 3:00 but I used my line of site the way the photo is posted. Thanks Sifo, I will plug it then. the vibration was the same in the grips and the pegs and at the same time, only at 65+ mph on highway. It was a like a buzzing vibration.

Vibes don't sound like the front isolator. I never had my XB do anything I would describe as buzzy. | ||

Ok. I see now. my STT ran really rough and it ended up being the ECM. Had some serious backfires before I got in into the dealer. Now when start it cold, she idles fine for about 3 minutes, then starts running a little rough until warmed up. I was wondering if this tube could be the problem. | ||

I believe that is the port for the cali evap can. | ||

Since you are right there, and everything is opened up, you might want to consider doing a breather re-route. Didn't happen to check / notice that vent last time I had everything off. Now you got me thinking..... | ||
| Xdigitalx |
yea.. I cannot afford the kit, I remember seeing a couple people making their own but can't find the posts. It is the oily hoses coming from the heads, into the airbox? What... I connect them with "T" then route it into a catchcan somewhere and empty it once a month?? (from what I remember reading) | ||

>>>It is the oily hoses coming from the heads, into the airbox? What... I connect them with "T" then route it into a catchcan somewhere and empty it once a month?? (from what I remember reading) Yup. Made my own, not hard, can do it for less than 10 bucks. Only you do not have to have a catch can. The amount that comes out is very, very little. At first I ran mine down, and along the frame, then threaded it through, letting it hang in font of the swing arm, next to and below the oil line. But it kinda gets tangled with the spark plug wire, so now, I have it coming mostly straight down, and tucked on the inside of my oil-cooler. Here is a link:http://www.badweatherbikers.com/buell/messages/327 77/449739.html?1238910149 Some use an additional breather filter and/or catch can. I don't, not necessary IMO. Good luck  | ||

Plug that port!! Definite vacuum leak,should be capped or going to a carbon cannister.Not conducive to good running. | ||

Got some hose, 2 "T"'s and a small cap, I don't have a catch can or filter. I guess those can wait. Got a 190 Scorpion Trail mounted and balanced on the rear wheel ready to be installed, a new belt and NGK Iridium plugs, plus a new Idle screw cable and then a TPS reset... I think it just might run like a new bike. (not that it didn't run fine before) Next week the front Scorpion Trail goes on. | ||

Sweet, good deal. Run the breather re-route, and put the catchcan/filter on later if you still want to. It HAS made a difference for me. Can cruise at lower RPM much easier now, make riding in the city easier. | ||
| Sifo |
I ran a home made catch can for a while. I got tired of the filter turning into an oily mess so I returned it to stock. I never noticed any difference in how it ran. I did sort out my very twitchy low speed issues before doing the mod though. I'm of the opinion that if the breather mod makes a difference, it's nothing but a bandaid for a tuning issue. YMMV. | ||

hey what are you guys using to plug that port? I have some little caps from autozone but they dry out and crack instantly it seems. is there something that will actually last longer than a week? I've been through 4 i think... | ||
| Sifo |
I use a short piece of vacuum tubing with a screw siliconed in place. Any hardware/auto parts store will have everything you need. | ||
| Xdigitalx |
Crap... I bought this 2-pack rubber vent caps from autoparts store.... I hope they last longer than a week. | ||
| Panhead_dan |
It depends on how old they are. I wouldn't use them unless they are like the ones automotive OEM uses because I don't like getting under the airbox any more than I have to. The hose and screw thing will work more better. | ||
| Sifo |
The thing I really hate about those caps is they have fairly thin walls that eventually crack. The cap will pass a quick visual inspection as being in place but be leaking air like crazy. A vacuum tube will have a wall thickness that is a number of times thicker. | ||

I just stuck a golf tee in it | ||

Why would anybody want to carry that stuff around in a catch can? It is like blowing your nose and putting it in your pocket. Just run that hose out and let it hit the ground, unless you have some sort of a religious belief against it.... | ||
| Wolfridgerider |
Just run that hose out and let it hit the ground AMEN!! | ||

Because it is environmentally unsound? It isn't hard to dump it into an oil pan every once in a while then to take to a recycling facility after you do your oil change. I'm not a tree hugger, but it is common sense to not pollute. Either dispose of it or let the motor burn it. |
