I jumped startered the quad with a car and it kept wind and than after while it started. So I bought a new YUASA battery and put it in and it started straight away. About 2 hours after that I tried starting it and than it clicks , than slowly winds and winds than it starts. It took a while to start the same way I tried when I jumped started it with a car. I also changed the starter relay with my other yfz450r and it still done the same thing. Any recommendations to what the problem is ... thanks guys.
