Any news yet timpo?
LTP, I have a few days work to do, and then the plan is to nip down to Middlesex with my bike and let a firm have a look at it for a day or two. Then I should have a price and lead time to delivery.
As for GMX, well i tried but they have clammed up, as I asked for a better price.
Let's see what the Middlesex company say.....

I might do this to reduce the amount of mud
Yes, it may do Johnny.... the standard fender was like a sieve, and mud soon swamps the rad behind the headstock.
I have my rad off at present, and it was almost solid with mud and grass/seeds, making a wattle and daub effect. feck me it has taken some cleaning, soaking and the very careful use of hp water.
Now I have a UFO fender from the EXC, which has no slots in the rear section, so should help keep the fins clearer....
I notice that Touratech have dropped the 'rally radiator' from there webshop listings, so it's looking like it has been discontinued.....?
Timpo.
OK, I've just spent two days away down to Pace Products in Haverhill, Suffolk, having taken two bikes down there, one with a Touratech tank and the other in standard form to ensure any rad would be suitable for both applications.
They have made a prototype rad, 15% wider with no thermostat. The rad has a small expansion tank and brackets for mounting the oem fan.
The left hand coolant hose is retained and the right hand connection uses a short piece of 22mm silicon hose.
The price for the kit will be £350 (The Touratech/GMX kit was £850).
The examples of Pace Products workmanship I saw were of a very high quality, with stringent pressure testing, and all work is waranteed.
The prototype will be used to make a jig and it is expected that the first rad will be with me in a couple of weeks.
I have a couple of pics here fo the visit and rad build, I'll post them here tonight.....

I'm getting concerned about the amount of time my fan is on, even after cleaning, so will be keeping an eye on availability of better kit. Might need some advice on fitting though!
All the time I was talking with the PP engineer, I had the ease of fitting and vunerability of the unit once fitted in my mind.
The increase in core width is out of the throw from the front wheel. I reckon the rear of any front fender needs the louvres covering as immdeiately the bike is used on mud the louvres allow a cake to form on the centre of the core rendering it u/s.
When the fender louvres are blanked off, air is still able to pass around the fender and through the core.
As for the fan, yes they run almost constantly when on gravel or single track trails, this will lead to the shortening of the fan life and eventually the fan burns out, and son after the over temp light will illuminate..... then the riding is over. Costs of new oem rad and fan is shocking, so this really is a great mod for the trail riding XC owner......

The pics of the visit.....
First of all, thanks to Rushy for the loan of is XC, like I said I wanted to ensure the rad would fit both the TT tank and the oem bodywork.....
Phil has a chat with me and then takes a look into the problem.....
It was not long before a piece of core was cut to suit the small space in the XC's frame.....
The top bracket is tacked on and we agreed that even more core length could be added as we could mount the expansion tank behind the rad, so anoth 20mm was added to the l/hand end (this is just a piece of folded aluminium plate for now)....
Unfortunately the lower bracket is part of the original pipework, which will be redundant, so a new lower bracket is made up.
Brackets are also added to support the fan.
Mounted on the bike it gives the look off how much extra surface area of core is available....
Time to look at the plumbing. The rad will be a single pass, flow from right to left, so the top of the engine was piped to the lower corner of the rhs tank. Connection will be via a short length of silicaon hose.
The return piping to the waterpump will use the oem coolant hose.
The filler wil use the oem cap, and the expansion tank will use the oem hoses...
And that was it, the dummy will be made into a jig and this used to make up rads for us. It was a real eye-opener to see the techniques used in rad manufacture, and the staff at Pace Products were really keen to help solve our problem.
As soon as the first unit arrives, I will post up here some pics of it fitted.

Looking interesting ...
Thanks for all your efforts Timpo, will have to take a good look at my own rad at the weekend, not noticed too many problems with it so far but then i have the technik mudguard and TT grill so maybe less mud getting to mine.
How are you getting on with the new set up and the lynx fairing?
looking at rushys bike am thinking maybe we need to start a rogues gallery of our Xs
Cheers

Being wider, is it any more prone to getting bashed if the bike falls over?
The width is achieved by moving the expansion bottle to the rear and also having no thermostat housing.
The body panels are in exactly the same location.
And trying to predict how a bike will behave when it crashes...... I think there are scientists somewhere who do this for a job..... poorly!

OK, I've had a delivery from Pace Products, and it's been a busy morning.......
The rad looks good, now at the full width and with the expansion tank fixed to the rear of the unit.
So I set my stall out and started to fit the unit.
As I had planned, the unit would use as many as the original fittings as possible, keeping the cost as low as possible.
First off, the front lower mount needs fitting, using the oem rubber bush and screw.
Next up, the hot water hose is fitted, a short piece of 22mm silicone hose. Fitting is eased with a spray silicone spray on the cylinder head and rad hose tails. I left the hose clips loose for the time being....
On to placing the rad, and on it's way in the hot hose was put on the rad inlet. Easing the lower mount peg into the lower mount bracket, the rad moved into place, and the two upper screw/bushes were put in and tightened, with a dab of locktite for good measure. The fan connection was made on the rhs.....
On the lhs, the cold water hose is pushed on the the rad outlet hose tail. Care is taken to ensure the twist in the hose keeps the lower part of the hose away from the exhaust manifold. When I was happy with the run of the hose, the clips all the clips were tightened up.
Now fitted, it was time to add coolant. A mix of water and anti-freeze was put in. I raised the front wheel from the ground and lent the bike from left to right several times, until the level stay at the top of the filler neck. Then I backed off the small bleed screw just above the hose tail on the rhs of the cylinder head. This ensured no airlock was trapped in the engine.
I run the engine for a while and again added water if the level dropped.
Once the pressure cap is fitted, the engine was run up until the fan tripped in, and within 30secs, it went off, which looks promising......
Happy with the fitting, I dropped the TT tank into place. The two pics show the clearance on each side of the tank flanks.
So there it is, a cheaper alternative to the TT rally rad, able to be fitted to standard bodywork or the TT auxilary tank.
Next job is to make or find a radiator grill to protect the core of this new unit..... I'll google it now!

Looking good, and oh , its nice to see that beneath the skin your bike is just as dirty as mine
Very , very nice. Well done that man 
And, it appears to be doing the job just fine....
Gave it two shakedowns now, one a road based blast and the other was single track green lanes/trails. The fan has nut run yet once......
What can I say, it's been worth the hassle of visiting Pace Products, and they have a jig made now to aid production, so htere is the answer if you are using your XC and not happy with the cooling system....

Timpo, can you post who is the contact at Pace and what precise set of bits we should be ordering (or is it just one thing?)
cheers

I spoke with Mark this morning, and after popping down the shops on my xc this afternoon, and having the fan running nearly permenantly, i have also ordered one

There is a bike specific kit containing any extra fitting required to mount this rad.

you may have done this already but when i replaced a punctured hose recently and used jubille clips instead of the bmw clips, despite them being done up tightly after a heavy offroad day at the ryedale the jubilee clips had loosened and i was losing coolant, have safety wired them up now

i have 2 questions .1 maybe timpo would know best. is the a reason the is no thermostat ? is it possible to fit 1 on the big rad ?? and 2 timolga .did you ever measure the husaberg rad ? could it be made to work or is it a no go. i have a trip round south america planed and when im in the amazon were the is lots of mud 30-40 c and 90% humidity i think the is a good chance the bike will be getting verry hot but when in bolivia at 5000 metres the will be no need for a bigger rad . so i am not to shore what is the best thing to do is .maybe a oil cooler that i can bypass or a second fan or a bigger rad with a thermostat would be bast.
