jesus... it's not like our bikes have the power to rip the bars out of your hands if you give it too much throttle.
try the mod... I think you'll like it. start w/ one zip tie and if you think you need more, try and add another later. there have been instances where there was not enough room for 2 ties w/o binding.
it's all about personal preference. for me, I wanted to be able to go from closed to full open throttle w/o having to regrip or pregrip. How much precision you have over it is directly proportional to the amount of gray matter between your ears.
with that said, I just went to a slower throttle on my trials bike this weekend to gain more slow speed throttle precision because
that bike does have the power to rip the bars out of my hands.
