How to fix oil leak from exhaust pipe?

Hi,

I recently bought a Pro-Circuit pipe and Silencer for my
RMX 250. Everything installed easily, and the performance
increase was as advertised. The only problem that I have
is that oil leaks out between where the pipe connects to the
silencer and spews oil out all over my bike, making cleanup after
riding a pain. I called pro-circuit, and they said that a little oil
leakage is normal, but I would prefer not to have any if
possible.

Does anyone out there know of a method to correct this.
I saw something called a "exhaust pipe clamp" in my White
Brothers catalog -- will this do the trick? How about some
kind of high temperature rubber hose or silicon sealant.

I verified that the pipe and silencer are properly seated. No exhaust
is coming out...just oil.

Any help would be appreciated.

Thanks,
Tim Kelsey

Same thing on mine. Automotive stores do sell a variety of exhaust tapes
and sealants. I would avoid a clamp though.

High temp silicone seal should patch it up. Makes it a little harder to remove
the silencer though.

Doesn't your bike have a rubber slip on seal that covers the point where the
Pipe and silencer insert? My KX does, but it would leak a little until I put
safety wire on it.
I have heard that you can get some rubber tubing that slips over the joint.

The RMX should have a rubber seal with two springs for tension, if this
is not working try some smaller or stiffer springs. I have the FMF combo
with no problems.

You can jet leaner with the PC stuff. That won't affect the spooge
though.

How about eliminating the spooge instead of sealing it in. I run a B7
series plug in my RMX. No sealant-no spooge.

The high temperature rubber hose seems like a good bet. My KX comes
with one
between the same two components. I had to add a couple of small hose
clamps to complete the seal but it keeps things clean. I haven't tried
the hi-temp silicone but that may work too but probably not as long
lasting.

Thanks to everyone for the great suggestions.
Hopefully I'll have my RMX "spooge-free" by the
end of the week.

Again...thanks for your time.

Hi Jim,

Yes, my RMX did come with a rubber seal and two springs with
the stock pipe and silencer. I tried to use the same rubber sleeve/
spring combo with the Pro-Circut setup, and it leaked like crazy.
I even tried replacing the stock springs with zip ties and even hose
clamps, but the seal was just too big on one side, so
it still leaked. In the process of all of this, I ruined the rubber
sleeve. Maybe I should have bought an FMF pipe!

Thanks,
Tim

Hi MX Tuner,

What does the B7 series plug do that eliminates the spooge?
Does it just burn cleaner?
Do you have a part number for the plug?
Can I just pop in a B7 plug without re-jetting the bike?

Thanks

The plug stays at a hotter temperature.

It burns more cuz it's hotter

BR7ES, B7ES, and so on

Did you make sure you put it on the right direction?
On my KX, the sleeve is slightly narrower on one side. I accidently put it
on the wrong way once and got lots of spooge because the silencer side was
too loose.

That is simply not true. Running a hotter plug will prevent plug fouling -
only because the goo burns off of the plug itself better. Once the fuel
ignites, the plug doesn't do dick - so a hotter or cooler plug makes no
difference in operating temp and/or likewise spooge burn-off. I've seen MXT
recommend hotter plugs to RMDers and I've also seen those same people
testify on RMD that it worked - but every ounce of engineer in my says that
a hotter plug will do nothing for spooge. Jet leaner or stop buying KTMs.

1, install nitrous system.

2. get torch and remove KTM engine. Weld big flat plate to frame
bolt Briggs & Stratton to plate. Challenge Dream Cycle to drag race.

3. clamp radiator hose over joint in exhaust.

4. don't forget duct tape

5. give MXT lots of M&M's or other chocolate as bribe to rejet your bike.

She walked down the sidewalk, accidentally bumped into a man and he

ecstatic. The next day she bumped into a man in the grocery store, he
begged her pardon and another inch was added to her breasts. She was
in seventh heaven! She walked into a Chinese restaurant, collided with
a waiter who bowed and said, "A thousand pardons for my clumsy
behavior." The next day the headline in the local newspaper said,

I don't know one way or the other, but Holeshot measured the exhaust gas
temperature and the results showed 40 degree F change in exhaust gas
temperature for each plug heat range tried. 9 to 8: 40 deg F hotter. 8
to 7: 40 deg F hotter. Check out Holeshot's bulleting board, read their
posts, and ask them questions if you want more information. If that's
true, then I could see how a hotter plug rating could reduce the spooge
factor.

Tim,
Sealing the pipe/silencer should not be a problem, some kind of hose
or tubing from an auto parts store will work. I also use the BR7ES plug
and leaner pilot and main. I'm not an expert on spooge burnage, I just
know it doesn't leak. How did this thread evolve to KTMs ?

My friend I got the impression that yout bike is running a little bit rich
due to carburetor settings. Most probably in the 1/4 to 1/2 throttle
departmentm lowering the needle (clip to the top) can make some
difference. Also by changing the mix ratio from 32 to 40 : 1.

It works awfully well for it not to be true.

It will reduce plug fouling AND spooge out the exhaust.

Sure it does. It increases combustion temp, not operating temp. They
are entirely different.

Could be because it *does* work.

You're right. It just CAN'T work.

I thought that went without saying.

If true, then the spooge relationship is obvious. However, hotter exhaust =
hotter operating temp and I have read in multiple published works that
increasing plug temperature does NOT increase operating temp (and it doesn't
make sense to me that it would). Could be wrong though...I'd be interested
in looking at that data - what is Holeshot's web site address?

Yeah, I don't understand how a hotter plug affects engine temperature,
either. And sorry, of course I should have posted Holeshot's web info
in my earlier post.


http://www.ktm-racetech.com/home.htm

Then go to the message board. Scroll down a page or three to the thread
called 'What about running a 7 plug?' or something like that. Until I
got more info about the test setup, and looked at the raw data (was it
really steady-state in each case, what other factors could be involved,
etc.) I can't vouch for anything.

My wr250 also oozed from this connection when I changed my silencer and I
took the rubber tubing to an automotive store and got some radiator hose that
was the same diameter but I cut the piece longer than the original hose so that
it slids farther up each side of the pipe than the original. That was right
after buying the bike new (94) and it's never leaked at all since.

What dumbass would believe there is no difference in the spark plugs when it comes to fouling them! Fuck man hit up the sand dunes And excersise your theory. You’ll find out soon enough if the plugs are different. lol. You ride rich and run hotter plugs. Other options include fouling plugs every hour or burn the damn thing up😳. Your clowns running 60 to 1 either 1: pussy foot around and never get in power bandit 2. Have lots of money to replace pistons and rings twice a year
