What did you hack that out with Huzo?
I use a coping saw on Aluminium, works a treat

Nothing special mate, just a hacksaw with kerosene then a disc sander.

Nice thing about a coping saw, you can steer it thru 1/8" like a hot knife.........

Yes, very true.

Ok, I’m up to here..
New shock on and preload set to minimum gives a ride height about 15 mm lower in the rear than standard item.
I’ve slid the forks up the clamps 18 mm to give a vertical change of 15 at the front. My seat height on the wheels unladen is 825 mm give or take.






The luggage alteration is complete, seat is as low as realistically possible and I’ll knock over the GPS final bits tomorrow.
I will post detailed shots of the relevant procedural moves if anyone is interested..

Hey Huzo, What's your feedback on sliding the forks up in the clamps?  Better handling?  Any downsides?

Nothing that I could discern mate...
I’d wound the spring perch up the requisite amount to allow me to lower the front the same amount, thus preserving the geometry.
More or less...

During the initial press testing, some commentators found that cornering clearance was an issue:  have you been dragging the pegs since lowering the whole kit & kaboodle?

I’m buggered if I know how they do it mate.
I certainly can’t..

[Huzo]

I’m currently up to my neck in the process of making a full 1 3/4” exhaust system for the ‘85, to replace this abomination..


To achieve this small feat, you’ve to graft the new larger pipe to the head.
To that end I made a pair of these.

Putting them together looks like this...


and whacking the whole lot in the head resulted in this..


<br /
It can be seen that there is a recess in the spigot and this is to allow the new pipe to slide in and be TIG welded...
Now I’m waiting for the pipe to be mandrel bent to the pattern and throw the whole lot on...

Well done Pete. At this rate you'll have replaced every part on the bike by this time next year.

Yeah mate.
There’s a V 42.5 hanging on the shed wall..(half a V85)

[Huzo]

I cut out various shapes for the new mandrel bent headers.
The variables are radii top and bottom and degrees of bend. I experimented with 110 mm CLR (top) and 80 mm CLR bottom.
The image here is 110 top with more degrees of bend than standard and 80 mm bottom with less degrees of bend than standard. This is to give more of a sweep like on the Norge.




I have since opted for 110 mm CLR top and bottom, with the degrees of bend as in the mock up. I do not have a shot of the mock up in this configuration, but I prefer it...(just).
The 44 mm stainless tube is now in the mandrel bender.

I noticed that AF1Racing.com is listing BiTurbo rear shocks that drop the ride height by 30mm if anyone is looking to lower the bike.

I got these done on a water jet cutter.

Today I’ll turn the centre hole to size and dress them up.

What are the header gaskets like on these bikes?  Typical flat rings?

Yep, standard fare.

So I did..
The spigots are now ready to take the mandrel bent headers which will fit into the recesses....(you’d think..).

I would have run around the recess myself, where the clamp fixes to the spigot with my MIG, but I really felt that I needed the penetration...(who doesn’t ?..).
So TIG it is..

[Huzo]

Here’s today’s exciting instalment.
Picked up the mandrel bent pipes and ran off with them under my arm. They look like this.




Trimmed them to length like so...


Shoved them wholus bolus in the spigots I’d prepared earlier.


And I’m up to here..

[Huzo]

Ok.
Today I shortened the dimension where the header leaves the head by 30 mm, I thought it looked better.
Here’s a shot..

Also instead of flaring the 44 mm pipe that comprises the new headers so it would fit into the Y piece which is 48 mm I.D., I tapped around the 2” and reduced it so as to blend with the 44 stuff.
Anyway, bottom line is it looks nicer. I got a nice stainless clamp which supports the system adjacent to the swing arm pivot, it uses the original mount that held the cat. converter.


I have hit the joints with the MIG so it can be taken off and TIG welded.
Tomorrow it’s plot the location for the O2 sensor/s, then bore the hole/s.
Then extend the wiring to the sensors if required and hit the starter to see if I’ve fried the ECU....(hope not)
Oh, and while we’re on about O2 sensor placement..
I’ve read and been told by someone who KNOWS, that the proximity of the exhaust outlet at the head to the sensor, is about as close as you’d want.
I’m going to attempt to place them down near the bend where the pipes swing around the back of the crankcase. From what I’ve gleaned this location will be suitable, but if there are any comments I’m here to learn..

I'm impressed with your skills mate ! Your breaking new ground yet again ....

As long as that’s all I break FF.
Is that Quota out of the weather ?

[Huzo]

Ready for the TIG..

[Huzo]

The first time the tyres come off, I’m polishing the rims and sealing the spokes.

[frans belgium]

Hello
  Has anyone removed the cat. converter on one of these?  Put on a new y pipe and if so how did it go? Did you have to do anything else to the bike? Thanks

No

[Huzo]

Yes.
Dunno how it goes, but I’ll tell you in a couple of days.

[Huzo]

My input will be of limited value, because of the complete removal of the whole system to install this



It will not be possible for me to know which action caused which change if any.

[Huzo]

TIG’ed together.






Now..
Fit the O2 sensors, polish the whole lot and do up the bolts...

[Huzo]

Well it’s done..

I’ll need to gather some information though.
The small yellow engine light is now illuminated. There are no oil pressure or temp warnings., no other indications on the panel.

[PJPR01]

That's looking really nice...truly a customized Wee 85...engine sounds very smooth.

Thoughts on the V85 engine compared to the Norge - only asking as I'm not yet tempted to get a V85 at the moment, but they do look great!
