Yes, completely correct; it's an ITG filter. Buy them from a car motorsports shop and you shouldn't have any difficulty finding what you need.

I'm in France, and I've repeatedly found it's better to shop in the UK (efficient mail-order service and lower prices). I use, and cannot recommend highly enough, Merlin Motorsports https://www.merlinmotorsport.co.uk/

Nice solution Paul, that's exactly what the Keihin part does. Much nicer, straighter run with lighter action.

FCR's + Choke + Velocity Stacks with Rott filter....

Gregor / Chris

I just wanted to chime in here and stay that I am very interested in what you guys have done here, been watching this thread with great expectation for over a year now.

I would love to jump to the FCR's on my 07 SM....would be the best next big upgrade but the chokes are holding me back. I will say for sure that with a choke solution, I will be buying the full package for sure

With the stacks not fitting the SM and then the talk of a custom Rott filter is just the icing on the cake. Keep up the great work.

If you build it...we will buy...;)

Great work guys, I always look forward to the updates.

All the best...Kent

So, if you've followed my garage build you know that I've got more than a few irons in the fire. It's just been too busy for me to dedicate time to everything that I've got going on so I've decided to ship the bike to Portland. I would love to ride it but work and family are pressing and it's August and hot - not my ideal way to waste a week away and not the ideal time to shake down the bike.

So I'm going to ship it as soon as I find a decent shipper. Once it's in Portland there's a much better chance I will find the time to work on the chokes and figure it out. I will also finally be able to ride it and enjoy it - which, after four years of building is a bit overdue I'd say.

Chris has a week with my bike to finalize the Rottweiler setup so he knows his time is limited to finish that. I personally like the K&N's but I don't think I'll go back just because the new throttle cable linkage is so much slicker and smoother with much less drag - it's lighter than stock. So, progress on that front.

Gregor

what an amazing build .. it's been four years .. sooo is your build better than a Super Enduro?

now I'm catching 950 SE fever too ...

If there is one thing that bothers me, it is the heaviness of the pull on these FCR's. Do you have close-ups and a brief explanation to your mod that makes the pull easier?

It's funny you should mention the Super Enduro - we've been in discussions with someone about just such a bike and the creation of what would be the ultimate adventure bike. But until things become real it's just that.

As for the throttle cable: it was the change in orientation of the front cable bracket and the shorter and straighter cable run that resulted. Suffice it to say that Chris will be modifying all kits now to reflect the change and the "Full Monty" will have the reduced springs, new bracket, new TPS and new cables so it will be a lighter pull still. It's about like a normal bike and snaps back with good action.

The other thing I discovered, and something that everyone who has FCR's should check, is that the float levels directly effect the accelerator pumps ability to deliver fuel. When they're set right (and I haven't measured them, only adjusted to when they're working) the pumps give a good spray and make starting much easier. Obviously everyone wants the chokes and I'm going to work on that when the bike gets home. There's a few ADV riders out here that may be able help with the sorting.

Throttle linkage

Hello all,
I needed to take the tank off for some further modifications, so I took the opportunity to show you the throttle linkage I mentioned a little while ago. Sorry for the iPhone pictures... it seems I'm embarrassingly 'between cameras'!

The chief objective was to reposition the cables to allow mounting of a single filter detailed somewhere above. I've a 950SM with Chris' velocity stacks and, as you know, the K&Ns are a bit pants in this application. I also wanted to lighten the throttle action. I'd already lightened the springs as much as I dared, so the only obvious thing was the faintly ridiculous six-cable arrangement supplied by Sudco. So I made this:




Which shows the throttle at mid point so you can see what's going on.

There's a block mounted between the carbs replacing the original drilled plate affair, which doubles as a bell-crank pivot containing a needle-roller bearing:



Both throttle-lift spindles were remade longer and the bearings changed to allow the shaft to pass through... which allowed the mounting of a suitably sized lever-arm, clamped and pinned to each of the shafts:



The remainder of the linkage being made up from aluminium tube and spherical rod-end bearings. I found an extra bar was necessary to stabilise the position of the carbs relative to each other and ensure the action was always correct (the aluminium angle you can see here, mounted on stand-offs, which themselves fit into existing drillings on the carb body):



There's a facility to make tiny balance adjustments with a 'turn-buckle' arrangement in one of the tubes. Which finally allowed the front cable mount to be modified to ensure the cables approached under the filter:



Outboard of the cable mount is the TPS plate which you can just see in the picture. After some experimentation I'm using just the front throttle stop adjuster. The rear has a screw in place of the adjuster, lest something goes horribly wrong with the linkage.

Throttle nirvana with one opening cable and one closing cable and super-light springs! 4000 miles or so of mountain road thrashing after completion and everything is marvellous with the throttles still in perfect balance. I'm not 100% happy with the filter mount yet (it's a bit scrappy, and it touches the underside of the tank in one place), but it's almost there.


Thanks for the tip on the float level Gregor. I usually check when I've got the carbs off, and they always seem to be correct, but I do occasionally see differences in the pump jet spray when looking down the inlets before starting the bike. Nothing dramatic. I've always assumed this had more to do with the horrible ethanol-in-the-fuel issue we have over here. E5 is rapidly becoming the only 95ULG you can find, but I've recorded between 20 and 30% of ethanol when I could be arsed to make measurements!! Shocking. Leave your bike for two weeks and the pilot jets have gummed up. Which is just nasty.

Cheers... Paul

Paul, that is some exceptional work. Just a beautiful linkage arrangement. Simple and elegant.

You wouldn't like it. The 2007 950 Super Enduro was pretty well set up from the factory. Pretty decent power-to-weight ratio, balance, and suspension. Most of us have just been riding the shit out of the bike for the past 4 years, while definitely enjoying following your modifications of a 950 Adventure.

There wouldn't be much modification necessary on the SE, other then maybe a little more fuel, which can easily be solved by converting the left stock cannister to a reservoir, and the right into a two-into-one system.

What fun would a 415 lb bike with 100 horsepower be if you didn't have to modify it?

SE needs to be RC8R´ed...
100hp don´t hook up that good. Need moar power.



I really like these old threads. This one is just so freaking good.

I feel overwhelmed and inadequate when I see stuff like this.
I can manufacture little bits and bobs, but when the going gets though I have to open my wallet.
Spending money on stuff for the bike does not burt as much as for instance getting a new couch or a dishwasher.
My brain has allotted different accounts for different activities in my life.
The motorbike account gets more money than the buying stuff for the house account, strange what?
But I digress, beautiful job!!!!!!!!1

Thanks Rattis, but no need to be overwhelmed. The hardest part of any job like this is having the imagination needed to conceive a solution. A few machine-tool toys are essential too, but the rest is just practice, experience and a little maths... and a refusal to give up.

The biggest problem with opening your wallet to fix stuff like this is somebody needs to have already found your exact same problem, then built and developed a solution for you. If there's nothing out there, what do you do?

If I've the time, my approach is always to have a go. The harder the task, the more effort I put to it. I've a sneaky suspicion that a lot of the people subscribed to this thread are of the same mindset. Gregor and Chris for sure... certifiably so.

I encourage you to have a go. It's always a wonderful learning experience that yields interesting stuff when you're done. Just make sure you hide your new-found skills from your partner, otherwise you'll be making unique furniture, bathroom storage that pops out of hiding at the touch of a button, a silly-complicated free-standing shower with no taps (faucets)... oh and this year's project: a swimming pool. Each project usually starts with my wife uttering stuff like: "I think it would be impossible, but what do you think about...", at which point I'm hooked.

In the case of my linkage, it works remarkably well now, but what you don't see is this is the third iteration. I only see where it could be improved! Maybe a fourth iteration will emerge over the winter.

Cheers... Paul
