Hey there,

OK. A little background I am a bit new to riding and I was just given a 2001 CBR 600 F4I and it had been sitting for 5 years or so. So instead of taking it to the shop I have been learning how to work on it myself so that I know my bike. Anyway, I have replaced the tires, cleaned and sealed the tank (was rusted completely), bought a new fuel pump (old one was rusted out), new battery, new fluids. I think that is it, but I filled the tank and fired it up for the first time and it sounded amazing for about 10 minutes before I slowly but surely started to shut off on its own. It would not stay in idle unless I turnd the throttle a little bit. Then I took it for a ride and and it would do fine until I came to a stop in first gear, it would shut off. So I Thought it was the spark plugs? anyway I kept trying to start it and I tried keping it running with a bit of throttle, then gas started burning through the muffler and eventually after trying to start it too much the starter gave out and now all it does is click when I push the start button. It has been sitting in my garage and leaking gas though the muffler and now the tank is empty. What could be the issue? Fuel pump? Fuel pressure regulator? I have ordered a new Fuel pressure regulator, spark pluggs and a new starter:/ I really want to get it up and running by this weekend. This has been a long and frustrating process. Any suggestions?

 

1 After sitting for 5 years there was probably muck in the fuel.
It's probably made it's way into the injectors and now they are clogged with fine gunk. I'd suggest you strip the injector bodies and clean all the jets/injector nozzles and passageways, and clean the petcock filter too - it's probably also clogged. Fuel pump too.
2 These bikes don't charge much under 3000 revs and the battery is probably flat now, also.
Let us know how you get on..............

pull the plugs and see which cylinder is full of gas. sounds like you may have an injector, or injectors, stuck open and dumping gas into the motor. enough gas can cause hydro lock and result in a motor that cant turn over, and with an emptied tank and fuel coming out the pipe, that would be plenty. also see if there is fuel in the vacuum line on the fpr. if the diaphragm is ruptured, it can allow fuel to get into the intake and flood 1 and 4 as well.

 

Dude a clicking starter after cranking it for a while is a sure fire indication that the battery no longer has the amps to turn the motor. It is my understanding that F4i's need a fully charged battery to crank over for any length of time. Hook up to a battery tender for a day and you'll probably be just fine.

The fuel delivery is another issue. But the two previous posters have given you the advice I would give you. Bad gas, rust and gunk are in your injectors reeking havoc. Disassemble and clean.

 

Thank you all for the help! I appreciate it. Let's say the motor is hydro locked how do I get it unstuck or drain the fuel inside of it? is the motor or engine toast? Also, if the injectors re stuck or stuck open how do I close them?

I will let you all know what happens this weekend. I plan on changing the FPR and the starter, because even with a fully charged battery it still clicks when I try to start it. Fuses ad everything are fine too.

Thanks again!

 

If the motor is hydro locked that can be fixed right? or drained? the motor is not toast is it?

Thanks for all of your help I appreciate it. I will let you all know what happens. I cant wait to get on the road!

No not a problem - just pull the plugs, clean them and let the fuel evaporate off the top of the pistons. I'd put a teaspoon of oil in each barrel and then turn it over to help prevent any damage to the bores.(with the plugs out)
Your battery may still be toast - have it checked - sometimes they won't take load even though they say they are fully charged. Could also be a starter solenoid....also an easy fix. Clean out the injectors tank petcock and filters though, that's I think where most of your problems start. I'd also check the fuel pump as stated before.
Good luck

 

with that much gas in there, change the oil after you get the issue fixed. fuel that gets by the rings goes right into the oil. lots of fuel in the oil is bad for lubrication and will destroy bearings and things.

 

Thanks! This is a great help, I appreciate all of the advice. When you say check the fuel pump, what should I look for? I just bought it so it would suck to have to get another one.

 

Check the filter on the pump and the electrical connections and fuse to make sure you have it running at full capacity.
Pump is probably fine, maybe just a cleanup.....
