Kerker 4:1's blow and I'm not talkin' exhaust

[buickyouth]

Seriously, who engineered these sacs of garbage?
I can't believe how little emphasis was put into how the headers tie together and where it leads down the underside of the frame.
There is no feasable way to change the oil, let alone the filter, without dumping oil all over the headers. Furthermore, the middle gear drainplug is all but inaccessable. Since you should be changing your gear oil just about every, or every other, time you change the engine oil, it seems like removing the exhaust system every time you'd wish to do so is nothing short of retarded (no offense to our retarded XS riders).
Oh, what I wouldn't do for a stock exhaust system on my 79XS1100SF.
Damn you Kerker and your imbicillic engineering team. Damn you all to H-E-double hockey sticks.

The gear oil only needs changing once a year. I use synthetic gear oil, and after a year it still looks fine. I kinda forgot to gange my final drive oil for over two years, and it still looked good. The only gripe I have with the syn oil is that it will migrate up the threads of the fill plug, and past the plug gasket, and leave an oily area around the filler. Try a Jardine 4-2 system. Filter is wide open, and the crossed pipes looks cool.

Jardine 4:2

Any information on where I could pick a set of these up and ballpark on how much I'd be having to spend for them?

[TopCatGr58]

Check out Dennis Kirk,

They have several sets from Jardine and MAC, both 4-1 and 4-2.

Last year's price for the Jardine 4-2 was $540.99!
Jardine 4-1 black pipes with chrome muffler $341.99,
all chrome= $414.99.

Mac black header/chrome megaphone ONLY type/combo=$324.99
Mac 4-2 all chrome either turnout, or taper tip= $324.99.

All designs from both boast keeping all access to filter, drain plugs, center stand!

Still running an old solid black 4-1 Generic Mac from JCW 10+years ago, they(JCW) no longer sell them!!

Supertrap

I don't know who makes or sells the "Suppertrap" 4 into 1 but I have one installed on my 78 and it provides clearance to all the oil holes.

MAC Chrome 4-1

I bought these and put them on. It looks a little difficult getting the oil filter cover off but I might still be able to without taking off the headers. The space between the header pipe for 2-3 look wide enough to pull the oil filter cover through. Of course when I pull the drain bolt, I will get some oil on the pipe, but it should clean off pretty easy.

Only problem I am having with them is some blueing on on cylinder 3 and 4. Don't know if it is related to the type of pipe or the engine is running too hot on that side.

The price was good. I don't remember the shipping charges but the whole thing was under $300. The picture on the page looks just like what they look like. Compared to the dented headers with the pinhole and almost wide open exhaust the the PO had on this bike, it is much quieter now.

p.s.

If anyone is considering getting rid of an exhaust system for a 79XS1100SF (Special)...
...PLEASE LET ME KNOW!

This is normal for Mac. I was told the factory pipe won't blue because it is a double wall pipe, and Mac is only a single wall.

There's a stock set of special pipes on ebay. There at 200 bucks so far.

kerker

Hey buick. If you ever decide to get rid of that kerker let me know. I've been searching for one for a while now.I don't mind dropping exhaust to change filteractualy keeps the exhaust header bolts from getting stuck on like iv'e seen when you don't remove the stock version for some time.

I thought Kerkers were supposed to be among the better exhausts for our bikes. My headers are close under the filter but I can remove it ok (I do put tin foil around the headers to keep off any oil that spills). Do you say that you cannot remove your filter? I might be interested in them if Chevy doesn't get them (I thought XJ's took different pipes than XS's).

kerker

the kerker pipes run right under the oil filter ,doesnt matter xs or xj because they ran right under the motor,until bout half the distance then exit the right side of bike.I just loved the sound of my kerk with no baffles.Sounded like a big block chevy...lol.Deep and throaty and pretty loud,just the way i like it.
