I am a new rider...I bought a 04 yz450f last summer. I usually ride trails and do ok. Recently I went to an indoor Mx short track and caked it 3 times mostly because of too much throttle at inapropriate times. Can someone tell me an easy way to slow down the yz450 and make the throttle more forgiving, at least until my skill and confidence improves? Would A sprocket change or different throttle control help? Thanks!
