hey guys I just joined here because i am the proud new owner of a 1980 xs400. third owner bone stock 20,000km. Runs pretty good so far only issue is a bit of a funky idle. when cold it needs to be helped a bit but once warm idles fine. after long rides the idle gets a bit high. other than that she's awesome. I did an oil and filter change today and went to clean air filters and found them completely disintegrated. So im afraid to ride. I found an old forum talking about K&N RU-2970 filter bolts right up instead of the h tube. I dont want loose reliability on this bike. Its my first bike i just want to learn to ride the streets and have some fun. should i opt for OEM filters or will this K&N option be ok? I really dont want to start messing around with my carbs as the bike is running quite nice. but a washable filter seems economical. any suggestions? thanks guys
