Bro had a 98 670 formula z and was bragging about his sled to anyone who would listen. I ended up buying a 98 xc 700 shortly after him,and he proceeded to keep laying the smack down. So one day we lined up like 8 times....he he finally shut his yap. I then proceeded to kill his buds mach1.. bro ended up re gearing his 670,and then he was able to hang till 60ish. .then it was lights out again
