The previous owner of my '97 S3 did some strange things to this bike and everyday I seem to find something else thats makes me scratch my head. ANYWAYS...The support bracket for my carb seems to be the improper size or bent. (I included some photos to help.) The bracket around the rear breather bolt does not surround the bolt. It has a notch cut out so that you may take the bracket out with out removing the bolt. Well this makes for a oil mist mess all over my rear jug. Plus the bracket will not fit all the way down over the bolt, adding to the problem. Additionally it also seems as though I have to slightly "pull" my carb out in order to get it tight against the bracket when I bolt the air cleaner on. I know this sounds confusing but I hope someone out there can give me a little help and tell me that mine is all f***** up or what. This all boils down to I think its the wrong bracket. If any of u could send me a pic of how your carb is secured in there I could then tell if I need to order a new bracket. Thanks, Mike

That's the correct carb bracket, but it's been modified as you suspected.

You should be able to get a new one fairly easily and inexpensively. Use loctite on the bolt threads and it shouldn't leak.

The bracket on my S1W is also notched at the rear - perhaps part of the high flow / race air cleaner kit? I've never had a leak problem, but I coat my threads with Hylomar before I insert them. There should also be a locknut on that rear breather bolt, so you can have the nipple pointed where you want/need it and use the locknut to tighten the bracket to the head, and the breather bolt threads to the threads in the head. Should be the same as the one you show on your front head...or you're using the bolts in the wrong heads.

The bracket is still available new, I think it's like $46 or something.

As for pulling the carb towards the bracket, I usually have the opposite problem, I have to start one bolt in the head, then lever the bracket (and carb) back to get the second bolt to start. Do you have a gasket between the bracket and the carb? You should.

Yes I have a gasket between the bracket and the carb. Its about as thick as the gasket on top of the bracket as seen in the photo. As far as you sayin I have the wrong bolt in the head...I beleive it. I am thinking about purchasing a breather kit from Drag Specialties (http://www.shopv-twincycles.com/shop/productdetail .htm?productId=5906117&browse=549630&shopBy=6669&c atalogId=1137&gclid=CPHB_pqTpJMCFSgtagod4i5Eng). What do you guys think?

"The bracket on my S1W is also notched at the rear - perhaps part of the high flow / race air cleaner kit?"

Interesting the things you learn here... I never knew about the notch. I did get the race kit CF aircleaner and it didn't come with a revised carb bracket and my 2000 M2 does not have the notch on its stock carb retainer.

"What do you guys think?"

I think you save the money and get one piece XB rocker covers and PCV valves retrofited to your tuber. Used to be you could do this for just a little over $100 with dealer parts. Totally gets rid of the breather/bracket bolts, the umbrella valves, and eliminates a gasket and the sandwiched plate under the stock rocker covers.

I have that same bracket. I use some RTV on the bolt heads and it doesn't leak. Mine fits just like yours unless I really push the carb down when tightening that rear bolt.

I still have a modified old school setup. I T'd the breather and one side goes to the K&N up top and the other goes to a clear hose I use as a catch can and empty every 5 or 6 rides.

when you install the intake manifold to head seals, you are supposed to leave it loose until the carb is fitted, or it can put stress on the support bracket and improper fit..just a thought

Is that rear bolt grooved or is that a washer behind the bolt in the pic?

Buell82,

FYI-When you re-install the carb, install the carb bracket bolts first, then install/push the carb into the intake manifold, and then line up the breather bolt threads to the breather holes in the bracket; tighten patiently to ensure a good snug fit into the intake manifold. After the breather bolts are snug, remove the carb bracket bolts and install the air cleaner. This process makes lining everything up MUCH easier (don't ask me how I learned this).

The bolt is a banjo style bolt, with a washer on both sides.........Thanks for the help everyone.

The 'notched' carb support bracket was used on bikes that had a 90° breather bolt on the rear cylinder breather port. The reason being is that you couldn't remove the 90° breather fitting without removing the frame. So to facilitate removing the carb bracket the 'notch' was cut into it. It is NOT a modified part, but a regular OE production part.

AH. That explains why my S1W had a boogered spot on the frame and no nipple on the end of that breather fitting when I got it. Someone determined they couldn't get it in or out, so they cut off the end of the fitting to make it clear. Hm. At least they left enough material on the breather fitting
for me to get a worm drive clamp on the hose...
