oh a nother thing , a sponsered racer gave me a tekin dyno , they got a new sponser and equiptment , that thing was great , it allowed me to test a new motor or a good motor and see what kind of numbers it pulled , rpm , watts etc.... this was a big help as a newbie , alot of people will tell you that a dyno isnt needed and its not , it just helped me test and figure things out , and there a whole lotta fun if your into building your motors , there are a couple on ebay right now pretty cheap , good luck and go on the tone
