It had a hard life for the past few years as a dirt bike and the owner before that is the one who bypassed the oil pump. I think that when it was run as a dirt bike over the past two years I think it got run a bunch on raw gas no premix. I did a compression test and it was well over 150psi at least 160psi, i bet the bore is a little on the shiny side. It has low miles on it just over 1000 miles. To get it to run I had to squirt oil in the carb and turn it over then it would idle and stay running properly. Drives ok now. But the pipe is gacked internally and the guts rattle like mad, and i think its choking the motor out a bit i cant get much top speed out of it. It starts and idles real nice now. Ill pop a better pipe out of my collection and see how it goes then not bad for less than an hours work B-)
