Multi bike insurance for slightly modified bikes

[The Moose]

I think I should start this post by saying that I must have developed a problem. I've just agreed the purchase of 2 bikes and am about to pull the trigger on a third.

Having only had one at a time in the past, I only have NCB for one bike.

All bikes are (or will be) slightly and tastefully modified.

Who's the choice broker to use? I ask as all the insurers on the comparison sites seem to dislike bikes with mods...even silly things such as hid lights.

Most bikes out there seem to have modifications of one sort or another. Do people just not declare them and fingers crossed they get away with it?!
