How to replace fuel sending unit on 2004 yzf 600r

SOURCE: 1997 yamaha yzf 600r electrical problems

a jump box is nothing more then a battery with leads on it so where are you connecting it verses the new battery you put in the bike. that doesn't make since unless you are connecting the box right to the starter motor then it be constently running the motor untill you unhooked it. check all your fuses and examine all wire harnesses for damage, burns, or any mellting.

Inject some carb cleaner spray through the opened air filter while cranking.
Spark plugs work? timing on the camshafts ok?
Crank it without turning the throttle on.
Pull the choke cable if you need to.
It should fire up without throttle.
Use the carb cleaner spray to help it (don't spray too much.It will backfire from the carbs).

if all other lights and gauges work fine, its the bulb fried or bad contact or if led its fried. pop out gauges and have a look

i suspect the battery is problem.Also you may have an electric fuel pump that is acting up.

it sounds like your fork seal has failed,it wont affect your brakes but will make your front suspension feel a wee bit "soggy"and will affect your handling,i would suggest getting the seal replaced as evetually the oil from the faulty seal will contaminate your brake pads that will affect your braking performance,replacing the seal,sooner rather than later ,would be a wise move..hope this helps...cheers
