Idle sounds healthy brother!
Mine lopes like that too. I like it. You don't need a powercommander for just a slip on. Not worth it IMO for a bike of that age, assuming it runs good at the moment, which it sounds like it does. Change the air filter because it is probably dirty AF. Hiflofiltro or oem are both good options.
Thanks for the response, I like the lope I was just a little concerned because I haven't heard any other 600rr's that loped like that but glad to know im not alone lol. I will also definitely check out the air filter, it probably desperately needs to be changed if the chain cleanliness is anything to go off of. The bike runs great though for the 40k miles that it has, almost zero engine noise, no misfires, or stuttering. I think I might still get a power commander because to me the bike definitely seems to be running a bit rich, which is not necessarily a bad condition but I don't want the injectors to get gummed up or anything like that.
Hello fellow Floridian (nice under 21 tag)
Your idle sounds perfectly fine and when I got my bike I noticed the loping noise on many that I tested out. Everything sounds solid in the video and sounds good. I will admit that I ended up getting an '09 and it does lope like yours does in the video, however not to the extent yours does, however, still it seems completely fine. And with the exhaust it sounds really nice.
lol I knew someone would comment about the under 21 tag, I had no idea that was even a thing until I registered my first bike which is the shadow that can be seen in the video. I was just curious about the lope because the idle seems to be about 1300 when warm which is in-spec but every other bike I have heard has a "smoother" idle. Glad to know everything sounds normal to everyone, and in regards to the exhaust I absolutely love it. It is my favorite for my year of CBR, the only other exhaust I think might have a better sound is the Toce but they don't make it for the 2004.
Also, on a completely unrelated note, before I posted this I attempted to raise the idle using the screw to see if I could get a more consistent idle. The screw just keeps returning to the position it was at before I turned it and the idle doesn't change. This happens when trying to either raise or lower the idle, is something wrong with that cable? The bike also does not seem to do the auto choke to warm itself up, I don't know if that could be related to the idle screw issue? Thanks for the help
