Picked up a new 19 450 a few months ago, and I'm sure I'm in the minority, but coming from my 14 YZ450 I don't like the reduced throttle effort of the new bike. Yamaha reduced the pull by a clamed 20% starting in 15-16.....I forgot exactly which. Anyway, does anyone make different rate throttle springs or would I have to rob one out of an older throttle body? Yamaha doesn't sell the springs separately...….

Mcmaster-carr has an infinite supply of springs. Maybe look on there.
