dude, you are stuck on your own. there is no actual numbers anyone can give you, since you don't have gauges. This is definetly not the bike you want to start stunting on. how could anyone ever "race" a bike without a tach is stupid.
anyways....for a stoppie you don't need a tach. do not attempt stoppies if you are traveling under 40mph, it is possible the front will just lock up. if it does lock up, immediately let go of the brake and you will be ok. so you are going at 40 light touch the front brake, then lift your ass off the seat a few inches really fast and grab the front brake hard at the same time, as the rear comes up slowly release the brake.
for wheelies.....so search.. there are thousands of posts.
