It runs very well -all checked with Paul Baker at ARP race tech and unchanged from earlier filter (breath sweet).
CHT rarely goes over 88 when riding and 105 when standing still.

I'm considering one of these, but I read that small filters restrict performance?

Any info would be appreciated.

The theory is actually these are supposed to be the least restrictive of all filters -and they are hardly 'small' - I'd say the surface area is certainly larger than a standard filter.
My breath sweet filter's jetting was rich in comparison for instance.

Excellent, thanks Tim.

Just what I wanted to hear. Judging for size isn't my strong point!

Got mine from VE and came next day.
Really looked foward to fitting it to my TS1, unfortunately as carb is right hand side,tool box has to go and the the rubber elbow is compressed by side panel when fitted :cry:
Ideas anyone ?

With a TS1 you don't have to discard the toolbox.
There are aftermarket manifolds available to get around this issue, but a cheap way is to carefully and neatly dent inwards that bottom corner of toolbox that is causing the restriction with a suitable small hammer. A touch up to the paint work and all works well.
Unfortunately, the side panel issue is another matter. Just depends what carb you is using.

The 105 has been on the bike for the past year and used a fair amount with a breathe sweet filter.
It was dyno'd again by Paul Baker (SRP race tech) and everything tested and the needle changed to the leaner X7, so I'm confident even if, in theory, it looks very lean.
I'll be checking the plug colour and as always after re-jetting I kept an eye on temps all the way back (45 miles) and all was fine.

Quick Question for anyone who's got a Casa Powerflow, what are the dimensions of the oval entry flange into the Filter?
Also what is the height of the blue filter material to check if it fits in my tank cutout?

I use one of the BGM armadillo elbows as my engine is a terrible starter without the drain in the rubber elbow, the Casa elbows don't have the drain.
Just wondering if the 50mm filter diameter when squeezed on my Armadillo would suit the Casa Oval entry?

OK, got my answer, no the Casa filter is too big.
Hopefully they'll produce an elbow with a drain.

I'm wondering if one will fit my carb. There's only about a 1cm gap from the bottom of the carb to the side panel. Does anyone know the depth of the hose?

The hose is 55mm deep, but you loose 10 mm pushing over the plastic bell on the dellorto carb.

Thanks for the reply. Saved me a few quid. I was hoping this was going to fit.

Hi Mate
Not happy with the tool box solution as the rubber elbow hits the side panel still.
Who or what would you recommend for the L/H manifold option ?

LTH do one... 'Linke Nummer'... about 136 euro though... they are good though, lots of room and the carb sits level coming off the barrel

Here's a photo of mine under construction... I'll take another photo later showing complete...

Another photo of the left-hand manifold....

It does come out quite low in relation to the running boards but shouldn't matter if you're looking to use an under panel filter...
