				Hi guys we've recently upgraded from a rpm t1 to a rpm t2 and where my son races the top end speed is slower with the t2 but his lap times are as good if not faster than the t1 (this is over a few races), both of the engines are dyno as good as the same, as the t1 his not got the restrictor on as where he races is non msa, sprocket size for the t1 is 20/76 and we kept the same size for the t2, my question is with the t2 do they behave in a different way though the rev range, I ask my son for some feed back but didn't really get to much back! if so would a lower sprocket give more top end speed? Hope this makes sense! Oh racing is at Redlodge
