New Top End and Seized!? Please Help

[digem23]

I'm stumped! I bought this banshee, it was low on compression, so i re did the whole top end soup to nuts. Now maybe the quad has on it 6-8 new rides.

My buddy and I have about 2 acres in the back of the house and we built a pretty nice track (for the space we had) We're riding the track, he on the banshee i was behind him on a raptor when i see him coast to a stop, i notice some coolant dripping from the overflow (maybe only 4-5 drops) he tried to kick it over slowly and said it didnt feel right, now the kick is completely locked, the bike will not kick over.

Is it siezed? and how? Any suggestions would be greatly appreciated before i have to pop the top. How could something like that happen on a new top end?

Thanks in Advance

Did you break it in?

Did you do a leak down test when you put it back together? You can build your own for $20 bucks. Also, you need to make sure his jetting is correct. Give us a list his mods and jetting.
