We have recently acquired a JB mod 90 (cr85) that we are going to use only for motocross. We bought an airbox for it but the air filter seems pretty protected as is from the little bit of riding we have done so far.

So.....Is everyone using an airbox on these or not when racing mx? Opinions?

Thanks,

Usually what we do is install the air box if the person wants one,then jet the carb get it running spot on then remove the box and jets and save it for a rainy day
