De torq curve doesn’t the bike right. But it is a blast to ride. My son’s DFLX with a Woods 777 stock 103 engine and SE heavy breather and V&H upswing 2:1 without the quit baffle. More then stock compression will help the torq in the lower rpm. But this thing is faster from zero to 120mph then my RKS 114 stage 2 SE torq.
