Ole Lady is Leaking

[oldman]

While working on the Brakes this morning (replaced the front brake pads), I discovered that I have a leak from where the intake Manifold connects with the engine.  In the pic below I looks like I have two O-Rings that are failing.  I checked the other manifolds, no problems.



In checking the Manual I got off line, it appears that one can loosen the clip on the carburetor, then remove the two bolts where the manifold connects with the engine.  Replace the O-Ring, then replace the manifold in reverse order.   

Has anyone else done this??  What should I look out for???   Other Problems. 

(I have ordered the O-Rings)

I've done it on two bikes now, it's not a tough job. Replace all six at the same time, more than likely your other ones are leaking too, just not enough to get on the block.

Be careful not to pull the vacuumm hoses off when you pull the intakes. I couldn't get one of my hoses off, so I decided I'd pull off the intake first, then have more space to work with. I ended up pulling the hose off from the tee under the tank. I ended up having to pull the tank and air box to get the thing back on.

It's a very easy job, remove the pods if you have an IS, pull the spark plug boots, pull the vacuumm hoses off the back of the intakes that have them, remove the chrome piece over the intake boots, loosen the six screws (per side) on the boot clamps, remove the two bolts in each intake, and pull the intake out from the bottom.

Any reason to buy the o-rings from redeye, or just get oem?  Also, maybe it's easy, but I haven't tried it yet- any tricks to cleaning up the deposits on the block?

I used the redeye rings because they are viton; supposed to be better quality. I know others have found them in auto parts stores on the cheap, too.

It's not hard to get the gunk off the block. I just scrubbed a little with a sponge while doing a routine wash on the bike.

I did ordered OEM O-Rings.  Planning on doing the two that are leaking now, then do the others during the winter.  And yes Nitro, I will have to take the left Pod off to get better access to the #2 manifold.   The #2 manifold has the vacuum line for the "T" under the tank and #6 has the vacuum line running to the pitcock.  So I will disconnect them before I go vary far. 

As far as getting the gunk off where the gas has seeped, as Nitro says a little soap and water works.  I washed the bike yesterday after doing the front brakes and taking her for shake down ride (100 miler).

I got the OEM O-Rings in the mail toady.   Not much of a problem pulling the Intake Manifolds off.  Nitro was correct, I did have to pull the left Pod off to get the chrome piece off that covers the take boots.  Also thanks to him, I was able to remove the vacuum hoses before having issues.  I found that the two O-Rings were "flatter than pancakes".   Looks like a winter job to do the other 4 manifolds as they are not leaking yet.  It took me about an hour from the time I walked out into the garage till I had all the tools/jack put away and was washing my hands.   

Took the 'Ole Fat Lady' for a quick 30 mile ride.  No signs of leaking. Though I don't know if it was the "fresh wash bike syndrome" or not, but she seemed to respond to the throttle a lot quicker and had more power.

Glad to hear she's stopped leaking! I don't know about performance improvement, but my Standard finally quit the popping under decel completely when I replace mine. That last for about six miles before the bike was totaled.

Holy cr**!   I guess I am not going to change mine.  I want to keep my bike!  LOL

I should be safe then, got over 60 miles on her now.

You should be fine, I changed all of them on a friend's IS and he has a couple thousand miles on the cycle since I did the job. No worries!
