At the moment it's a bit of a kitten. I was going to do the standard K&N and Micron job, but a couple of people have suggested that this might be a bad idea. My main reason for doing it is not so much to make it faster (although that's never a bad thing), but to make it a little more audible. Also, it idles a bit unevenly, so I suppose I need to do the carb-balancing trick... but it's a 1998 fuel-injection model. I was wondering - firstly, does anyone else think it's a BAD idea to put an after-market filter and end-can on it, and secondly, is balancing carbs the same when you have them as when you don't (if you see what I mean)?
