Information: ''83 Yamaha IT250 frame grafted with an ''80 Yamaha TT250 motor. First woods test of combo 1-27-07. Works great. I''ve ridden the tires off this thing since I created it last winter. See each photo for other comments. Always a lot of comments when I get back to the trailhead. People who have ridden it say it reminds them of another 4-stroker they have ridden. It is not quick as it doesn''t have the throttle response of the YZF bikes, so I don''t get into trouble with that, but it will get up some speed and keep up with the crowd. I''ll upgrade to something newer at some point, but when I need something reliable, I take this one.
