I bought a second K&N filter and when swapping them out I noticed quite a bit of oil inside the airbox? I've seen this before but not a puddle of oil, so my guess is that it was over coated with oil from the factory.
Seen in every one of mine too.... After some use (mileage) and clean up in airbox it subsides. My guess as well, over oiled at factory.
ANY change to the intake, or exhaust, requires changes to the ECU and/or a power commander to fix the fuel/air ratio. The exhaust alone can just have the ECU mapped with the Akrapovic map. If you are changing out the air filter, then you'll also want to do the airbox lid mod. Either would necessitate the power commander.Guys, i was thinking of dropping in a K&N filter once i install my Akra pipe, i am keeping the stock tune as i'm happy enough with it and the bikes given me no performance problems. Could anyone provide me a cut and dry answer if i can do this without damaging the engine? or will i have to go the akra map if dropping in the K&N in addition to the pipe to prevent it running to lean and potentially damaging the engine?
Cheers.

Hmmm, ok i thought as much and glad i asked now Think i'll just add the pipe and leave the filter for the time being. I have been running 95ron (australia) in the bike since new which is what the dealer told me to put in it. I like the idea of using 98ron BP Ultimate as it has a slightly better injector cleaner package. Alot of blokes at work have bikes and most tell me they have run 98 in all their bikes for that reason alone as it only costs about a dollar more to fill up and has helped keep their injectors/ carb clean (bike dependent). For the moment i still running the 95 as i'm unsure if running the 98 will have any negative effects to the bikes engine etc?
I have a couple of bikes with intake mods either modified or removed airbox lid or pod filters, and often the intake noise is louder than the aftermarket exhaust under more throttle input. Including my RC390
Question ? Just installed the K& N filter with an aftermarket lid - also have a fuel pipe and PCV installed with mapping to suit by qualified tuner- My question would be to anyone else with the K&N and lid mod - Is it normal to be so load in the intake department under hard throttle?
The bike is running clean and crisp but it does overpower the exhaust tone with a massive BRUURP ............ sound (intake) It sorta makes it feel underpowered but i'm sure its all good as it blasts in mid range- etc.. does anyone else find the sound up there on Db?
I was curious about this too. My last K&N air filter was for a carburated bike and it came with an insert for the airbox inlet to reduce air flow for use with stock engine/carbs/pipes. Does the K&N KT-1211 come with anything like that for an otherwise stock RC390? I don't need more performance but, I'd like a re-usable air filter.Guys, i was thinking of dropping in a K&N filter [...] Could anyone provide me a cut and dry answer if i can do this without damaging the engine?
