Bad Bike Day

[Gas Man]

Oh yes... the fuel pumped carbed bikes... my buds honda shadow is that way. His would still start but it had a blown relay.

Do you have a service manual? This is why I tell all you grasshoppers to have one.

[JoJoYZF]

I have a haynes manual, no actual service manual.

A lot of times the fuel and blinker relays are the same and can be swaped to cheak them. Not always but a lot of the time.

I still say try the jump my wifes F4 had a bad battery it would take a charge and would crank the bike for about 5 min 6 seconds at a tiem of course then die. The battery was just weak may be a cell out and the bike would start right up with with a jump from a strong battery.

I assume you have a car and cables its a easy way to check the battery.

Again I ask have you done any maintenance lately it always sems to be the problem. Even if you only lifted they tank or seat to look at some thing you could have pinched a hose or unpluged some thing and did not notice.



Carbed bikes are easy to see if they are getting fuel they have a drain screw on the float bowls you only need to open it. Bad fuel pumps on carbed bikes are common because they are very low pressure and volume. They are only there to over come the pressure of the ram air system and or the fact that the carbs may be higher than the bottom of the tank.

They have to be weak or they would bypass the float valve.

Most carbed bikes will start and idle fine with out the fuel pump aslong as the carbs are filling(lower than the level of fuel IE: fulltank) But then run like crap once the speeds increase or the revs build faster than the carbs can refill.

I'd put a little gas in the carbs and see if it starts...

Gee it's too bad that someone didn't post a way for you to get a manual online for free....

Dont pat yourself on the back too hard, you posted one for a 1999-2002 r6. I dont ride an r6, I ride a yzf600r, different bike.

Man I have spent the last half hour trying to figure out how to send you this fucking repair manual!!! Grrrrrr!!!!!

Well there's your problem...


Hmm... that's true but wouldn't the R6 manual help?

It may help some. Im just trying some fairly basic stuff so the haynes is helping.

Question time. Now that the bikes in pieces right now, how do I know if the fuel filter is trash? I think it may be but Im still not sure thats the problem. And right now Im pulling the spark plugs to see if they spark or not.

Gas is WAY better at this than me but you can pull the gas line and run it into a container, turn on the key and see if you are flowing the proper amount of gas per minute. To be honest, if you haven't changed it, it's probably due by now. The main thing to look for is if you are getting gas flow at all, if not it's your fuel pump.

Thats what Im thinking. The filter looks kind of dark inside with only a small section that is clean that looks like it flows properly so Im going to hopefully get a new filter tomorrow morning (all 3 main dealers around here closed at 6) and Ill probably just replace the plugs since I have the bike pulled apart already and they look a little rough.
