Well i went riding at my practice track last night and wake up to wash my bike. The first thing i do is pull the air filter off and the U-Flow chamber , to come across it is full of dirt on the inside and my carb has chunks of dirt laying on the inside. I have no idea how my motor didnt blow up. There was dirt laying in the chamber of the U-Flow , heres pics to show everything. And yes i had my air filter on tight and it was tight on the carb so where could it of came thru at ? Im so aggravated right now and whoever wants to buy this junk off me its for sale. Ill be sure to send this same thing to BBR and let them know about this.
