K3 GSXR coil pack

[Tim..]

Doing some service work to my friends K3 gixxer.
Got most of the jobs done but when it came to changing the spark plugs the coil pack on no4 cylinder is stuck fast. It wont even "spin".
Tried many different ways to move it (with force) but was worried about breaking it as he needed the bike the next morning.
I find it wierd because it wouldnt be something i expect to get stuck.
I guess my question is has anyone come across this situation berfore and what was the end result?
Thanks

Tim

Also if someones got a manual handy and could give me the correct spark plug gap for a K3 Suzuki GSXR 600 it would be very helpful.
Thanks
