F4 Fan removal?

Hope someone can help me with my F4 750 track only. Last time out on a trackday the temp. of the coolant was at a steady 86-88C. Never overheated all day despite a near 40c air temp.
My question is this.
I want to remove the two fans as they appear to be redundant for the use I give the bike. Is it as simple as removing the hardware?What about the rest of the loom? Will I have any other side affects?
This may sound a bit simple but I have a black hole where my knowledge of electrics should be.
Thanks in advance.

There will be more room for Guinea pigs in the space made available, Ade.

On the later versions of the F4 it is just a case of removing the fans from the loom - there is one plug each on the right hand side of the radiator (riders perspective). Unbolt the fans from the radiator. It's safest to move the radiator forward to allow good access to the bolts securing the fans to the radiator.
It's a relatively simple job.
I hope that this helps.

Two things. Less weight and greater flow of air through the radiators.
If they never come on, why have them?
I hope to make my 750 as light as possible, and the first step before spending on lightweight wheels etc. is to remove useless bits. I have already filed away the seat lock mounting and some lugs on the subframe. Now the expensive stuff starts I think.

Thanks. It has helped to put me at ease when tinkering with something I do not understand.

Leave em on!! the loss of the minimal weight wont make and iota of difference one way or another BUT you will still have a cooling option WHEN they are required.

i dont think removing them will give any greater airflow impact.
