Are 2stroke dirt bikes allowed?

As long as it has a stock pipe i believe,they are strict up there so be careful

Need spark arrestor and law states it can't be louder then a stock exhaust

I rode my 2 stroke YZ250 there but people are right. Need spark arrestor. My pro circuit shorty probably doesn't meet the standard. ☹️

I think I've seen a banshee or two while I was there, so I would imagine they would be ok.

Need spark arrestor...94db or less.
