Question about Yamaha YZ 450 F Motorcycles
You don't have to buy a new spring, just relocate the stock one. There's another little arm in which you can cut a small groove to hook the spring. It isn't so tight this way. I did that and the 450r throttle and there's a HUGE difference! Also - heat fatigue the spring with a mini-torch will also make it softer. If you dont want to modify - you can go with a lighter spring. http://i219.photobucket.com/albums/cc197/buttmusk/CIMG3827.jpg Check with your local dealer and im positive he can help you find a compatible one. THanks for using FixYa!!
