main fuse 79 kz1000

whats up kz peeps, seeing if anyone knows why my main fuse is hot to the touch, i cleaned it up and seems not as hot, my forth kz1000 but this one is new to me. any input is appreciated, thanks

Corrosion , corrosion, corrosion... Clean all the terminals. Never liked the bullet type connecters. Put all new space type connecters.Also I ended up putting the small blade ATC type fuses. Used a 6 place fuse holder which had a cover too Even had slots for extra fuses too. I did keep all the original parts though.
