Now, if you keep this bike mechanically, and have adjusted everything right, kept it in good condition ( as with ANY other bike! ) it runs like a firefly! If you dont get it going well, then you, or the previous owner have done something wrong. Great bikes to build a flat tracker/ brat / scrambler / cafe racer on! a lot of fun for few pennies ! And a lot of spare parts on the marked! Low cost, easy to work work on, runs WELL , fun to customize, great handling, light weight +++ Get one! N.B do NOT use synthetic oil on these bikes!! This is a veteran, with WET clutch , and would require at least 20W / 10 MINERAL OIL . I use mineral , classic veteran oil 20w/50 on mine! runs PERFECT!
