All you have to do is google Hayabusa R1 throttle mod and threads will pop up. Read and find which years work, they'll even give you the part# to go and order from a yamaha shop
the new supersprox quick accel kit is pretty nice (-1 front +3 rear). i also had my yoshis cut in half. the new gearing really woke up my bike. obviously creates higher revving in lower gears and changes shifting somewhat, but well worth the $.

one pic shows the yoshi before the cut.
the shifting changes a little because the gear change creates higher rmps in the smaller gears, upshifting sooner.
Did you cut the yoshi's? Yourself?
If so, with what? If not, who did it and what did they use and how much did they charge you to cut them?
I really like the looks of the shorter pipes. The only thing I might have considered is cutting them so
the holder clamp just came up to the label on the pipes. Maybe it was not possible to cut just one quarter to one third off, IDK ???
the gold chain is from supersprox, comes with the front and rear sprockets.
my mechanic knows a guy at a muffler shop who did the cuts and re-riveted the cans. i assume he uses a chop saw. he charged me $150.
they sound a lot better, louder on hard acceleration, not so much different at cruising speeds, but a much meaner growling sound.
as i said, this combo really woke up my bike.
