Also it states all gaskets are included for the job, that not accurate, it comes with head and cylinder gaskets only.Took the bike out for the first time yesterday and it is a rocket. It makes allot more bottom end and the power band is incredible. Used Athena's recommendation for the jetting and it was pretty close just need a little fine tuning.I would recommend this for advanced riders; the yz is fast out of the box and even faster with this modTime will tell on durability."
