Hi, My bike lost power after about 1hr riding in the rain, it felt like fuel starvation, it lost complete power,I tried starting again soon after but it just spluttered, after 10-15mins it started again and was fine, this has happened twice now, any suggestions folks as to the cause? It's a cbr900rr 99.

 

Hi Liverpool Blade, welcome to the forum.

Can you give a little history on the bike, mileage, mods etc. Was the rain really heavy?
It sound more likely to be water into a connector from what you are saying with the heat from the engine drying it out before firing up again.

We also love pics...

I'll contact you a bit later tks

 

Which connector would that be?

 

It had Dyno Jet kit fitted years ago, k and n filter, Evo blue flame twin pipe exhaust, About a year ago similar thing happened, I put that down to adding some cleaning mixture for carbs into the tank, it died out after an hour riding, it spluttered and stopped about 4 times as I tried to ride home. I drained and refuelled it again and up til couple of weeks ago it ran perfect. It has 39k it's 1999. I store bike outside with two covers on, it stays dry but I suppose there's condensation always. I thought about a new fuel filter and pump and getting the carbs checked, which connector could it be. Tks

 

Thanks for the additional info, is there any crud in the tank, did you check the petcock filter when you drained it? These bikes can get quite temperamental if there is any dirt around which would necessitate a carb strip and clean.
If it is electrical I would start with the ECU and R/R connectors and work from there onto the ignition circuit.
As an out side bet, the engine stop switch on the handle bars does have a habit of failing over time.
Unfortunately these intermittent faults are an absolute pain to try and nail down.
Good luck, some of the more learned folk on hear that have had blades will chip in in due course.

 

Thanks for that valuable help, I'll try those ideas first and let people know what happens next, this CBR forum is very helpful. Cheers
