nice bike!

thats one nice looking bike. i got your reply which is very helpful. what did you do about the exhaust valve? i've read that if you unplug it,the red engine management light stays on. is this true,if so how did you get round the problem?

many thanks.

Hello Tim
I bought a tamburini front system wich removed the cat and valve.
And made my own carbon mufflers.
Just dont disconnect the valve motor leave it on the bike , remove the 2
metal strings that are connected to the valve.
If you start the engine the motor will activate (as it should) and the ecu will think that the valve is still on...
I had no problems with fuelling or such , Brutale' s are very rich in fuel on standard trim so a full system is no problem with the standard ECU
