Not bad per se, but not optimum. The air box provides some 'smoothing' sharacteristics to the air. Without a airbox, the air filter is subject to crosswind and changes in airflow patterens. All of this can serve to reduce power. As a side issuem, if you ride in the rain or durt, filter problems can arise.

I have to ask, what carb and main jet are you running?

I do have it jetted for this, I have a yosh pipe on this set up aswell. I dont have a camera for pics yet. I havent had any problems with it at all. The outerwears helps a great deal for not having to clean it as often. Looks killer.

the intake bell isnt tapered.the sharp edge is creating turbulence at the air jets.

to make a long story short,you slowed it down.
