i have a 2012 txc250 that is develpoing a stutter off idle under certain loads aprox 2500-3000 rpms.it has aprox 20 hours on engine,and completely stock.i run good premium fuel with lucas oil octane booster.flameouts are also a problem.its always had a cough in that same rpm area from day one.i attributed that to being new and colder temps in the midwest.this is my first husky and really like the bike butt hate that it has these running problems.any help or suggestions would be greatly appreciated.
