Hi y'all, I have a concern about my blaster. I seems after I've rode it for 30 minutes or more and the motor has cooled down for quite some time and is on level ground, I look at the little sight glass on the rear brake side of the motor it shows no oil in the little sight glass.I've put more oil in to bring it back up soo I'm wondering if someone has that same concern. Thanks,blasterman312
