Well i was going to put the TAV yellow sring on hole #3 but i know i need a later upshift than that so i put it on hole #4.
"Hole #4?? It doesn't have 4 holes." haha.. well it does now.
If you have a modded motor with a T/C .. you haven't felt acceleration yet until you've been on hole #4.
I am now a bit curious about hole #5. It may possibly be overkill.
