Hi i have a 2000 honda cbr600 fy
After the bad weather i decided to clean the bike before i cleaned it everything was running fine. (Cleaned with a low pressure hose and muc-off) when to start the bike the next day it seemed to start ok but soon as i went to ride it i noticed it was bogging alot even with small amoutn of throttle.
about 1/4 of a mile and the bike got worse and died and wouldnt start again.

ive drained the carbs (2 only had a small amount of fuel about 10ml each 2 seemed to have 2-3times the amount in) checked the plugs for any water all wires seem good sprayed all connections with Gt85 the battery is brand new and charged fine.

Ive seen a few people with problems like mine but not the exact same. Any one else had this happen or have any idea?

 

Hey Cake,
My list of suspects would look like this:

-Bad spark (possibly caused by water getting into the coils)
-Stuck floats (could be flooding out those two carbs that had a lot of fuel in them, or starving out the two that had little fuel in them)
-Fuel pump (could have knocked the wires loose with the wash)
-Clogged fuel filter (cause it's cheap and easy to replace)
-Fuses (cause they're cheap and easy to replace)

I'd start with the fuses and confirm battery voltage (even though it's new, this is always my first step to troubleshooting a no-start)
Then confirm spark, and while each plug is out you can check if they're fouled (rich)
If they're rich, check out the choke and air filter, and if that doesn't fix it you might be looking at a stuck float or other mixture problem
For bonus points you can run a compression test while pulling the plugs, but if it was running fine before, this is unlikely to tell us much unless it had a sudden catastrophic failure
If the spark is good and plugs are clean, you are probably running lean, which would point us towards fuel delivery (fuel pump or fuel filter)
If fuel pump and filter check out, and it's still running lean/rich then you might have stuck floats or other carburetion issues. They might just need a good cleaning

 

Hi Tentacleslap, thanks for the reply.

i think it was down to a sticky float in the end i dont have the tools to take the carbs off, but gave them all a soft tapping put the bike back together and its been fine ever since.
I do need to check the plug but again lack of tools, and a stupid bar over the top of the plug paps thats part of the frame makes it even harder.

Im hoping the bike was just having a off day, as after a long ride today its still running perfectly.#

Again thanks for the help.

 

Glad you got it running. If she gives you more trouble, adding a bit of seafoam or octane booster to the gas might help clear some of the gum out without having to take them all apart
