I just bought a CBR F4, and I had the engine running. I was sitting on the bike and rev'ed the engine a little and it just shut off. Now when I try to start it, it just sounds like it wants to start and backfires sometimes. Actually it backfires about every 5 to 10 sec. when trying to start it. Any help or suggestions would be greatly apprecaited.

Thanks

 

make sure all of ur carb boots are still connected and sealed good

 

Thanks, I will try that. I also bought new plugs and air filter, to try and see if that is the problem as well.

Thanks agian

 

Check the fuel filter also. It could be plugged.

 

Change your fuel, add 1/4 bottle of heat. Change the plugs. Do an oil change. These are all things you should do with a new bike/any bike, at the start of a new riding season.
