Do the K&N's work well with Suzuki or should I just send it back??
I assume the bike is new and stock already. I wouldn't bother with a K&N until it is time to replace the stocker. Air filters do last a while. It might flow a bit better, but how much it will really affect a stock GSX-R 600 I don't know.
Also do you have any suggestions on a filter and oil for my first service?
I'm not going there :lol: Ask ten people that question and you will get ten different answers. If the bike is new, synthetic would be a good call at your first service. It is a bit pricey, but from what I have seen at the track, it has saved many a motor from pure destruction that dino oil might have caused.
I have run dino oil for years on hi-po M/C motors w/no issues. I am using synthetic in my 1100 race bike now, however.
K&N oil filters are good, Suzuki filters are good, AMSOIL filters are good. There are a lot of disbelievers in Frams and their construction methods, but I have had no problems with them.
