Hi there

Is it possible to upgrade a 2014 YZ450F with the new lighter throttle return spring of the 2015 model?

I didn't find a part number for the new spring..

I looked too couldn't find a spring... looks like you would have to buy the throttle body or send yours off to injectioneering.

Let me know if you find anything.
