Ok another question i got a 19mm carb now with an mrp pipe,i moved up to an 80 m.j and my needle setting is at secound grove from the bottom of needle,my needle has 5 groves,i rode the scoot to work the other day and got it up to 40-45 mph but didnt want to stay at that high of speed for to long,so i kept cruise speed to 35mph,im running 8gr rollers because i didnt have any power frm 3gr all the way to 7grs,i lost my take off though so i ordered some 1500 rpm clutch springs and might order main spring today(1500rpm),should i keep the 80 m.j or go down to a 75,also ordered a tach so i can see what my rpms are doing,will going to 9gr weights give me a little more topend?
