Re: kawasai z750, keeps blowing main fuse
To my knowledge, there are no onboard electrical/electronic components capable of shorting and blowing the fuse with out blowing any of the secondary fuse. The main fuse could possibly blow due to a short in the wiring or an exposed/frayed wire touching the body. The three most likely areas would be:
wire harness leading to the regulator;
wire harness leading to the fusebox; and/or
wire harness leading to the ignition switch.
Just a start, do postback how things turned up or should you need additional information. Good luck and Thank you for using FixYa.

Ive had my bike at a workshop for the last 4weeks getting a freshn up . ... If the fuse isblowing that quick you should be able to find it quickly , probably .... eliminated the dash and reduced the amount of things you need to look at. .... SL750 / Dorsoduro 750 · 2008-2014 Mana 850 and Mana 850 GT-ABS.
Providing you've got the right fuse (10A) then the place to look is the regulator/rectifier. If this is failing then it will be throwing to much power through the system and the main fuse is blowing to protect the bike. they are an easy plug off/plug on item to change..
Forget the other answers bud...here is a link to kawasaki vulcan riders club where some real bikers n experts to guide ya through buty I also added few links to free repair manual downloads.....got tons of links for other bike stuff if ya need...
finally lots of vn parts are cross compatible and this site does a nifty bit of kit that finds part numbers and then sees if its used on other models...it isnt free but might as well be...saved me a packet at breakers=
Some newer bikes aren't supposed to be jump started. Take the battery off the bike, replace the fuse, charge the battery on a proper charger overnight (as opposed to a battery conditioner like optimate). It should now start fine and not blow the fuse.
If that doesn't sort it, the dealer will need to reset something.
premium gas with some octane booster for a couple of tanks should do the trick because even though you cleaned the carbs there still is gunk and **** in the lines..i also suggest fogging the bike with seafoam good luck i hope this helps
remove and test fuel pump relay if the fuse to it is good.try swaping it with another one like it just to see if thats it.(or using a test lead with a fuse of its own see if you can bypass the system power at the pump to make the pump work,that way its only the pump you are testing instead of the whole fuel system)
