Well, sorry for my english... I'll try to clear.

I have a 94 CBR 900, it does'nt start anymore. it's the second time it happens, first time it took me 6 hours with a friends to look EVERTHING we could, we removed the fuel tank at least 15 times to try, and then it fired. Got no problems for 1 month.

Now. same (*#?(*#? thing. there is just no fire. It doest crank for at least 10 seconds without any sight of fire, and then POW. one backfire. not two not three. ONE.

What Ive done so far, removed the sparkplugs, cleaned everything with the a air compressor so I knew it was not because there was too much fuel. took the continuty between all connection so I know the wires are OK. There is a small module on the frame with 3 or 4 wires, it looks like the connector had suffer from heat. I cleaned everything and make sure the contact was good.

This is not suposed to be complicated... theres almost nothing, but im totally lost now. I just dont know where to look anymore.

Anyone had the same problem ?

 

well I am not shure but I would check to see if the plugs are geting curent and if they are then thetiming might be off
