Hi Guys, I've recently fitted a K&N filter to my Bandit 600 and now have a very noticeable flat spot at 4000/5000 revs. I'm assuming that the carbs need rejetting as a result of the new filter but need some advice as to whether or not this is likely to be the case or if there is anything less drastic I can try (I'm going to refit the stock filter in the interim until I can get this sorted). Any advice you guys could offer would be appreciated! Many Thanks Dan Ricketts
