Ok I'll start by stating I'm no master mechanic, or even really a mechanic. I am very familiar with bikes tho. Ok so I bought a 99 CBR 600 f4i and it was great! Had really no issues with bike for a month or so. Reolaced a fuel pump and relay to only to continue to have issues. The bike seems like it's not getting any petrol still tho. Will turn over until the battery dies. Maybe the fuel pressure regulator? Plz plz help me before I lose it

 

Hi, you say your bike is 1999 ,but is it f4i or f4

 

Good question.
There is a huge difference between a 99 F4 and a 00 F4i.

 

The 99 f4

 

Well in that case, let's put it in the F4 section.....

First thing to check is for fuel in the carb bowls.
