h/c
actually, no. When you apply weight to the middle of the h/c, you will often see the response of the engine slow down alot, this is because the h/c weight already acts like a progressive angle helix and will upshift very aggressive. With the new helix being slightly more aggressive on the start, its really upshifting quickly now. To keep the engine revving at a constant smooth rate, you need to move the weight out to the tip, this will allow the engine and clutch to be at the same upward rpm climb rate, with the low finish, you will need more tip weight to control the topend rpm, along with better belt clamp, you also are grabbing the belt better in the front and the rear. The lower finsih angle clamps the belt harder in the secondary, and as a bonus, you can run less secondary spring press. and gain more topend as well, because of the low finish angle.
On the other side of the coin, lets say a piped viper, where you need to run higher topend rpms to be in the meat of the pipe(9100rpm or so), I run more heel weight, barely any middle weight and no tip weight, you just need to have the correct helix angles and it works extremely well.
