Post by: BrettS on August 05, 2013, 12:15:29 PM
Now were cooking with Gas!

Well almost just gota wait for the other half of the exhaust to turn up.

It'll be interesting to watch this mod.
Keep us all posted MAD brett
This machine might have to change names from dusty to glossy

Still plenty of dust there Jonesy.  8)
Well I have more than enough parts now thanks to Christian.

The old exhaust is ready for the bin
(https://xs1100.com.au/forum/proxy.php?request=http%3A%2F%2Fimg14.imageshack.us%2Fimg14%2F331%2Fu1f7.jpg&hash=faaac57328768bde85dea70f368ec15406662621)
The first problem was the end bits are longer than my previous ones. The clamps from the old exhaust helped but I still needed to get longer stud bolts to accommodate this.

Probably the most surprising issue I had was that the headers would not line up in the collector. I mucked around with this for some time before I decided to adjust the collector box to suit the way the headers came from the block. Not sure how well the pictures show this but either the inner pipes needed to be longer or the outer pipes needed to be shorter, also the angle was some what out as well. I would be interested to know if there is any difference between the blocks from the XS to the XJR or if this was just an anomaly of mine? Anyway I am now very happy that the collector and headers go together pretty easy and I don't believe the flow will be considerably upset.
The pipes are a very snug fit in the exhaust outlet, this shows how the pipe was too long on the out side exhaust.
(https://xs1100.com.au/forum/proxy.php?request=http%3A%2F%2Fimg43.imageshack.us%2Fimg43%2F6721%2F4ygl.jpg&hash=b9e54a979a8182622dfc35fe25db804d6ceca2c5)
Here the pipe would just not go into the collector box any more.
(https://xs1100.com.au/forum/proxy.php?request=http%3A%2F%2Fimg23.imageshack.us%2Fimg23%2F7319%2Fhrwz.jpg&hash=41f1a02da9709e6c175118cec241ddb22c3ef657)
This cut allowed the position to go down and change the angle as well.
(https://xs1100.com.au/forum/proxy.php?request=http%3A%2F%2Fimg850.imageshack.us%2Fimg850%2F1207%2Fyqmh.jpg&hash=3313158778f9bd12b610784dadb4b14235a62276)
Ok now we're back on track, Mad Bill cut the collector box top and bottom to adjust the angles. I saw no reason to do it this way and it causes a large gap on the outside of the bend. It is much better to cut say all of the inside bend and then all of the two sides leaving the outside bend intact. This way the bend closes in on itself.
Like this,
(https://xs1100.com.au/forum/proxy.php?request=http%3A%2F%2Fimg845.imageshack.us%2Fimg845%2F1259%2Fo6yx.jpg&hash=745ab83af3250a6ba48434d9dc5a13f747635eea)

Then when tacked together there is no gap to fill.
(https://xs1100.com.au/forum/proxy.php?request=http%3A%2F%2Fimg203.imageshack.us%2Fimg203%2F9461%2F6dv6.jpg&hash=08ff149112b3cbe8c720307cdef645d22e55f0ad)
And again with the muffler end. Just cut the inside of the bend and leave it connected at the top. This closes in on itself leaving no gap.
(https://xs1100.com.au/forum/proxy.php?request=http%3A%2F%2Fimg819.imageshack.us%2Fimg819%2F5688%2Fl3mz.jpg&hash=83c4ab5f1669d326e8513a12a59c46e6d53d49e0)

Almost there, I ended up getting the collector box a little closer than this in the end.
(https://xs1100.com.au/forum/proxy.php?request=http%3A%2F%2Fimg843.imageshack.us%2Fimg843%2F6940%2F7v5u.jpg&hash=1158da22c435a61b2295e108c70142c4048998df)
Just need to double check everything in the morning and weld it up.

Nice work Brett
You certainly got stuck in
From our ph conversation at mid morning when you hadnt really started to being ready for the final fit up at days end with a post as well.......another no oil cooler convert too 8)

Once I stopped thinking and drinking coffee (some times that goes on till lunch time  ::)) I can actually get something done.Posting gives me something to do winding down with a beer after. Early start today  :P
I forgot to mention about the oil cooler. You could find a way to keep it but it was just one less thing to worry about so yep off it came. I also forgot to mention I found the centre stand mounts got in the way so I cut them off as well.
(https://xs1100.com.au/forum/proxy.php?request=http%3A%2F%2Fimg443.imageshack.us%2Fimg443%2F4555%2Fe3jp.jpg&hash=072743e05caa9a0f6aca500082a7b3761771c9bd)
The mount on the collector box is no longer used so that came off too.
(https://xs1100.com.au/forum/proxy.php?request=http%3A%2F%2Fimg51.imageshack.us%2Fimg51%2F4920%2Fd0e3.jpg&hash=76fc651d696b399a79117c0a1ba17f7d01ea9bef)
Collector box fully welded

I did J2's idea and got the oil plug drilled n threaded to take the temp gauge. The machinist was a little worried it left the plug wall a bit thin but so far so good I have an engine temp gauge, just need a speedo that keeps working to use it  >:(
(https://xs1100.com.au/forum/proxy.php?request=http%3A%2F%2Fimg163.imageshack.us%2Fimg163%2F3279%2Fy4ik.jpg&hash=435892c5857e1a88e4b64c1b66bbbb6593d220bb)
As the mufflers mount onto were the rear foot mounts go I found it easier to remover the lock nut so I could do the nut up instead of trying to turn the foot peg.

Comparison of the modified collector box. Any bets on how long the spray can acrylic pain will last?

It is very quite and smooth. Rather large but I like it, some how it is starting to remind me of something you see in a matchbox model  8)
Seems to have a slight lag down low but I am sure it needs a new tune now so can't call it yet. Seems to be very smooth otherwise, I love it.

Nice work but that rear shot wouldn't inspire me to take it into the Alps  :o :o :o :o

But then your roads are all straight down there!  ;D ;D

Very happy thanks Paul.
LOL it might lean over a bit more than you think Steve. I would be pretty happy if I managed to rub these on the tarmac.

Great work Brett...........well documented as well....I also like the way you took a good idea and made it better .
What is the scenario with this system  for :
 1) Rear wheel removal
2) Oil filter replacement
Title: Re: Mad Brett's XJR Exhaust Mod
Post by: Christian Raith on August 18, 2013, 08:07:18 AM
Oil filter slip out 2 & 3.. Put the spin on adapter and half your oil changes

Hey Bryan, some times it is hard to get me going but once I start  ;)
Thanks Tim hope you and the guys are having fun today  :D
Haha Eddie, the Misses is getting a bit jealous she reckons something new is turning up for the bike every week. The fact is there is ALOT of work to do and if I new what I was doing and had lots of money I would just do it all in one go  :P

Thanks Jeff, I have had heaps of advice here so hopefully my documentation helps some one else out. I have never taken the back wheel off so I have no idea but the two rear mufflers come of with just two bolts each so shouldn't be too much trouble.

Christian sent both sets of headers and collectors I believe with the idea that I could modify the other for some one else. I am happy to do this if any one is interested. Cost would be minimal, when Christian gives me details to pay him for collector and headers, my total cost is $195 

It was said that these will add extra 15 hp, I have had a bit of a tune up today and taken for a good hack. It seems a little slow of the mark but old dutsy may not be the best test. I will get a fully rebuilt set of carbies new leads n coil then dyno tune for the best jets before I can conclude anything?

Maybe I sound a bit harsh in the last post. From 0-100 through the gears is bloody great. Yet in a roll on in top gear from 60kmh there is a little lag before it gets going. Probably good for old dusty but Bryan would leave me in his dust of course. Will be interesting to see were this exhaust goes with some work?

LOL Scotty, thanks Hen.
I keep forgetting to point out a mistake I made. The cut on the collector to adjust the angle of the mufflers should have been further back on the weld.(Mad Bill wasn't that silly) This would make it an easier weld and also stronger. One simple fix for this is to cut it all the way off at the weld and just weld two new 2" pipes back on. That will be a one day job  ::)
