This is where the value of these track attack videos will be evident.
Standing start: 38:60
Rolling start: 37:22
The Helix in stock form ran 38:51 for the standing start and 36:53 for the rolling start. The bottom line, as you'll see from the vid results, is that those clutch mods didn't help us at all. In fact, we were a little slower, more noticeable on the rolling start. We also lost a few MPH on the top end in a top end test, but that was kinda to be expected because of the 12 gram sliders.
This doesn't mean that clutch mods don't work, this is just evidence of the need to pick your mods wisely and pick your mods based on your riding style. For OUR particular type of riding, where its mostly a flat track, the clutch mods don't help us. If we were trail riding where top end doesn't have nearly as much value, the clutch mods would be great.
Anyways, here's the vid:
