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!!

04 yfz 450 wont start with electrical start


i have a 04 yfz 450 quad. the compression ratio like yours is extremely high. ive had my battery go bad and found that another battery other than factory would turn over the engine, but would not start. i paid the 100 dollars for the factory battery and it fired right up. because of the high compression you need a high cranking battery.
