While working on the mount issue I had to pull the carb before replacing the head. The M2 has the CF race air cleaner. Dealer did the install for the previous owner. Both breather bolts are 90 elbow fittings that joined with a tee fitting which was basically 'glued' to the flat aluminum backing plate with some sort of rubbery sealant. Funny thing is that the left side elbow fitting can't be removed since it hits the frame when you try and unscrew it. Parts manual shows two straight bolts. Wonder how they got that left side fitting installed? I want to run the breather hoses to a remote external filter (orange one to match the frame and wheels of course). Has anyone installed one of the rigid tubing style breather assemblies? | ||

The stock ones are straight, the 90deg fittings are used when an after market intake is installed. With out seeing a pic of the problem it's hard to recommend how to remove it. As for the rerouting of the breather lines. Unless you have done the XB rocker box mod you will get oil spray and spooge coming out of the breather line. You need to run some sort of catch can with a filter. | ||

Yeah, I've thought about those billet cans that strap to the frame. As is, the hoses off the 90 degree fittings run flat to the tee fitting and then straight into the backing plate. No elevation from the breather connection port, so I already get quite a bit of 'spooge' entering the filter assembly which then drips down onto the CF cover. I want to run the line up from the breather port level so any liquid stays in the head and only the air comes through the hoses. Only way the dealer got that left side fitting in is if he dropped the front of the motor down to gain clearance. Hmmmm, could they have removed the front mount bolts to do that which in the end resulted in the bolt issue? I'll try and post a picture, but the fitting won't turn due to interference with that curved section of the frame near the air box. Safe ride, Gary in Oaktown | ||

Hi Gary, I installed one of rigid breather assemblies on the Sportster a few weeks ago. The breather bolts (elbows in your case) get replaced with banjo bolts. The new banjo bolts hold the rigid crossover pipe with hose fitting and two brackets that are used to mount your air filter back plate. It works better than the Orchard Supply solution I had on there before. I just ran the breather hose under the bike with a breather filter on the end. It would work just as well if it ran to a catch can of some type. I should have kept that baby bottle breather. Barry | ||

I think I know your issue. I think it's hitting the bracket not the frame. Don't loosen the motor mount. The carb bracket has an entire loop on the right side so you have to take the breather bolt all the way out to get the carb off. The rear or left one is shaped like a C so the carb will slide out with the breather still in. If you take the intake off and loosen the carb you can get the bracket off, and then the bolt will spin. There is a debate on not wanting to keep that spooge in the motor. I run my 90 elbows and all the lines downhill to my catch can. | ||

I think mine did hit the frame now that I think about it more. I had to grind the lip off the side that the hose goes on. Not much just enough to get it to miss. I would try to do that before loosening the motor. | ||

You really should consider running a catch can or a dump tube. Do you really want that spooge going back into the motor? There is a youtube vid where the guy just ran the hose down and ended it at the exhaust tip. After seeing the crap I drain from the catch can I don't think I will even do the XB rocker box mod. I would rather drain a catch can once in a while than let that crud recirculate back into the crankcase. | ||

Hey Barry, Good to see a post from you here if not on BAS LOL! I do like the idea of the banjo bolt system. Just need to fine that seller on eBay again. That baby bottle worked well for ya and I guess Mike's termination points at the end of his swing arm is still working too. Did you ever have that engine mount failure on your S3T? With the long trips you've done I don't recall hearing anything. Catch can is something I'm considering too. I made one for the Sportster out of 1 1/4" copper plumbing fittings (I'm a plumber) one time, but it looked too damn industrial LOL! Besides, on the '90 the breather comes out of the cam cover and everything was easy to access. Safe ride, Gary in Oaktown | ||

Hey Gary, lost the drive belt a few weeks ago on the Benecia Bridge, but haven't had any motor mount failures. I did replace the rear isolators when I installed a new belt. | ||
| Dpg |
Hi Barry, Yeah, I'm not looking forward to the belt change and rear isolators. I was lucky some of the guys pointed out the tightness of my belt when I had that shop replace the tire. I hear you're taking a ride out to Yosemite soon. Safe ride, Gary in Oaktown | ||

My race aircleaner on the S1W has 2 90 degree fittings, too. Rear hit the frame when I got it. Dremeled off the lip (it was a nipple shaped fitting, now its just a tube) and use a hose clamp on it now, and it clears the frame so I can remove it. The note above is correct, though - the rear bracket hole is C shaped. You can loosen the rear locknut, remove the front bolt, and the bracket will slide out from behind the rear bolt assembly. Yours *do* have locknuts on them, right? | ||
| Dpg |
Yup, both breather bolts have lock nuts. No gaskets of any type though other than some sort of thick black goop which I guess the dealership put on as a sealant for the threads. I ordered a metal tubing breather assembly so there will only by one connection point. Will run to a catch can and then the filter on the end. I'll seal the AC backing plate with a piece of metal tape used on heating ducts. Safe ride, Gary in Oaktown | ||

It should have some very thing washers that go between the head and backing plate IIRC. It will probably work without them. That black goop is called Hylomar. It won't get hard and can be reused to seal it. If not I used some red rtv on mine. (Message edited by skntpig on June 29, 2009) | ||

I use some big soft copper washers I got from Harbor Frieght on the breather bolts. The kit I got had some plastic washers, they didn't seem to last long. |
