Hello,
I have recently discovered, that once my cbr’s engine is cold (usually after the night) and I start it, the rpm seems to be a little high. It starts at ~1900-2000 rpm and once bike gets warmer, slowly climbs torwards 2500-2700 rpm. + once I rev it a little and release the throttle, rpm seems to stay at one spot for a second and slowly drops back to previous rpm. Though, once I turn the bike off and start it up again after like 10-20 mins, everything runs great. Rpms are at ~1500, and they drop nicely after a rev. I already googled, that most common causes of this are not lubed throttle cable and air leaks. I have checked the cable already and its definitely good. I am not sure about the air leaks though, as I dont know should I look for one.
but can this be an air leak issue if the problem dissapears once bike is restarted?
thanks for your replies in advance!

 

I'd start with simplest solutions first. Lube the cables, check your grips are moving properly... clean the throttle bodys... while your getting to them, check the air intake system for obvious issues... sounds crazy, but I've fixed so many things in life by just cleaning them and lubing them up... good luck 👍
