Default Cbr wont start

Came home from being gone this weekend, started my bike up about 3 2 hours ago perfect sounded great. Came back an hour after from going to the store to get a few things and the thing will not start. It will crank well, then ill here a start that ends real quickly..

I am thinking it has something to do with my fuel filter or the engine not getting any fuel. Anyone have any advice here? im so confused as to how one hour is fine then nothing!

help me out please im working on it right now

Well the bike is now trying to start its hardest.. It is trying to start every few times spuduring, it tried and then backfired which means its really trying to start but its not for some reason..

Anyone think they know what could help? would changing the spark plugs help? it sounds like only 1 or 2 are actually trying to fire..

thanks please help!

I recently had a similar issue. I have no rational explanation, but out of desperation, I cleaned the plugs and it started... It can't hurt to try new plugs!

Thanks for the response.. Im not very familiar with plugs for motorcycles, I have heard that they dont need to be gapped.. Is that true? also how can I deflood the engine? I think i may have flooded it.

You are correct, don't attempt to change the gap. I'm not sure why...

As far as the flooding, you can just wait, and the gas will just dissipate or when you pull the plugs, just leave them off for a few. It will work itself out...

After looking at the wiring schematic, I would suggest looking at the engine stop relay and the 20A fuel injection fuse. My bike occasionally won't hot start, and I think I'm going to start by replacing those.

the hanes book I have says to check your plugs at 16k miles, and to change them at 32k.

So it was definitly the plugs guys... All that worrying about little old plugs that are a B**ch to get out if you dont have the honda spark plug wrench.. I cant tell you how many times i went to the hardware shop to get different attachments to finnagle my way in ****...

But put them all in and it started like a freaking champ... Loud as ****
