AIM Brake pressure - over mudguard vs H brake lines
Discussion
After some wisdom if anyone is willing to offer it please!
Got a new AIM dash fitted to my GSXR600 track bike this weekend:
I would like to add a brake pressure sensor to this, would be nice to send someone out faster than me for reference data and gives me something to work too.
I have picked up a pressure sensor and a line to suit that comes with a banjo fitting on the end. I currently cannot fit this to my master cylinder as it has a double banjo set up with twin lines on the front brakes.
I guess I am going to have to replace the brake lines with a single line from the master cylinder so that I can fun the double banjo for the pressure sensor.
I have seen an over the mud guard option on lines, with the second line linking the two callipers over the mudguard but have read that it can be a pig to bleed and also not the best in terms of safety if you have a mud guard let go?
Other option from HEL is a H set up which I believe splits over the lower yoke which I guess keeps it clear of the mudguard but it is also a 4 line kit so there are then more fittings with opportunity to leak?
Any thoughts or advice please!
Have read about some people running the double banjo for the pressure sensor off a caliper but I am nervous about running a sensor so far down the forks and also having to deal with fork movement with it.
How do race teams deal with this as I would assume most run the double brake line set up.

You could fit the pressure sensor line to one of the calipers with a double banjo bolt and mount the pressure sensor under the bottom triple clamp if the hydraulic line is long enough.
Otherwise, you would need a take off T union building into one of the normal lines although I'm not sure if anyone offers that option.
And fwiw, the ultimate pressure you will measure is not really the key data point, rather the speed of the initial pressure application and the pressure release vs track position and lean angle that will give you something of interest.
But before you dive too deeply, look at your throttle application and time at WOT vs a fast rider and I'll bet you you're later on the gas and sooner off it despite similar apex speed values. This is usually the most telling metric between fast and average riders.
