I have an 08 YZ450F. I am racing harescrambles with it this year. The one thing I don't like about the bike is it loves to stall in the tights stuff. I am going to run it in the first three races as is then make some decisions. I am thinking a flywheel weight will help curb this problem? I read a post about the GYTR 9.4 weight? I am mechanincal but I am in no means a bike mechanic. Is this something I should try to tackel myself? What is involved. Another thing is when it stalls sometimes it will fire right back up with 1 to 3 kicks. Other times I have to let it sit for at least 5 minutes before it will kick over. Why is this and how can I fix it? Thanks for the help!
