here is a 1986 lt 250 it has a brand new top end on it as of july 5th 2011, I also went thru the cases replacing all seals, gaskets, and several bearings, it has a brand new UNI filter, a 34 mm tmx mikuni flat slide, douglas red labels all around, fmf gold series pipe, it is a nice little bike and if you take care of it it will run for a long time. it is on its first bore so a 70.5mm piston, it can go up to 72 I am pretty sure. good little bike! $900
