Bike not starting

[w_mendez1]

Hi: I have a suzuki 2004 gsrx 1000 with about 23,000 miles. I started having problems starting my bike about 2 week ago. In order for my bike to start I have to pull on the gasoline knob, once I let go of the knob the bike shuts off. I took the bike to the dyno and they told me that the fuel mark was really low. F1 or FI flashes on the electronic display. Hope you can help me solve the problem. Thanks in advance.

We're going to need some more information but it appears that terminology will be a problem too.

What is a "fuel knob" ? And what it a "fuel mark" ?

If the "dyno" you visited wasn't a Suzuki dealer, I suggest you take it to one.
What did the people at the "dyno" tell you you needed to do ??

Ok. In order for my bike to turn on, I have to turn the accelerator and start the bike, once I let go of the accelerator the bike turns off. The guys at the dyno showed me a graph and they said that the line that represented the gasoline was not hardly feeding at all and I had to leave the bike so they could search for the problem but I had about and hour drive so I could no leave the bike. On the electronic display F1 or FI goes on and off and on and off.

On a fuel injected bike, just having to turn the accelerator to start it is a bad sign; that should NOT be necessary, and in fact often makes it harder to start.

It sounds like a fuel pressure problem; fuel pump or filter or pressure regulator, if there is one.
Not likely you can properly fix it yourself. There may be some sensors involved too.

You NEED to arrange, however you can, to leave it at the shop.

Clarification: you really need to leave it at a shop that has the suzuki obd2 scanner.

btw have you run some carb cleaner through the engine.
