I used bel-ray H1R to break in my '04.I let it warm up good and rode it for hour real easy then turned off and let it cool all the way down and do that again.After that I babyed it threw another tank of gas.When I went back for tune of the mechanic rode it and said that it was a strong bike,and a kid brought his '04 in for trade in and mine was faster than his.
my friend across the street has an old lt 50 and the back wheels wont turn and we were towing it to our house.We tied a rope on the back of a fourwheeler and on the lt 50 and we were going down a dirt road and the 50 it a bump and it rolled over side ways 5 times it was funny as hell
