Well I Get my bike out to run the other day and it wont start would it be possible for the bbr rev box to have fried something else electrical on my bike

The stator, the ignition pulse generator, the ignition coil, and maybe the voltage rectifier.
Have you a volt/ohm meter? What are the symptoms?

[Lets Ride]

Have you kept regular maintenance?

Symptoms would help to.

well it will start if the choke is all the way up and i cant give it any gas other wise it shuts off, and i changed the spark plug, but today i check my air filter and it was BLACK i cleaned and it still wouldnt run but my friend suggested cleaning the carb considering where my air filter was so dirty dirt may have passed through to the carb

[gal8x]

I think you friend is right. Clean the carb. Pull the jets and blow them out.

I have a BBR revbox that is a paper weight. I tried to use it and my Bike was acting like yours. Try your old box. Maybee you have a bad box like I had.
