I still don't have an answer as to if the new filter is worth it. Once I do, I'll be sure to post about it.  |
You need to remap your fueling. All performance air filters have the basic ability to supply the engine with more air than stock (hence the classic line "the engine breathes better"). Till recent times, the stock fueling on most vehicles was good enough to compensate this increased air with more fuel. With bs4 it got tricky and with bs6, almost all vehicles run stupid lean. Manufacturers are using every trick in the book and then some more, to qualify for the stricter norms.
My bs6 rc390 was so anemic when I bought it first I was wondering if I made the wrong call. It had absolutely no power below 5000rpm. Ran way more hot than my bs4 d390 (I always thought it was the fairing that caused the heating) even though both vehicles had engine ice coolant. And it had the very very annoying problem of stalling when downshifting from 2nd to 1st gear when rolling to a stop (rev matching helped only a little bit).
5 months down the line, I was very upset and was almost thinking of letting the rc390 go. My 2017 rc200 never gave me any issue like this and was ready to race from the first day of delivery. The only thing that kept me hanging onto it was it's crazy ability of carrying insane speeds through corners. And then I saw a YouTube ad for fuel x pro of, I think it was a Himalayan. And then i thought what the hell, let's go for it.
Got the fuel x pro and K and N performance filter. Set it up myself, took 45 minutes. I didn't want the adjustment buttons outside so it took a few cable routing techniques under the fairing and now it sits pretty inside the battery compartment. The default setting for fueling was at level 3. Started the engine. The bike growled to life in a way I had not heard it before. My eyes lit up. Took a test ride. It was indeed pulling better on acceleration and I was able to hear quite a bit of the engine as well, not just the exhaust. But the stalling issue persisted. Stopped the bike. Opened the battery cover. Set the fueling level to 5. Heard more of the engine noise and the startup growl was even better. My grin widened. Pushed the level to 7. Started the bike. Now the engine noise was far more prominent from the seat. Almost muted the exhaust note. Put on the earplugs and helmet. Still could hear the engine roar on revving it up. Slotted first gear and opened the throttle. The bike almost lifted it's front wheel. The acceleration was manic. And the best part, there was no stalling no matter what I did. I could not stop grinning the entire day.
Took an hour long ride that night. The bike was running like a dream. It had better power delivery than my d390. No stalling. Had lesser vibes and over time, gave me better fuel economy. I suspect that would be because now i could run a higher gear at lower rpm for the same speed while cruising without the engine threatening to disintegrate. And to this day, I can't stop recommending the air filter and fueling mod to anyone with a bs6 vehicle.
P.s. it cleared the PUCC easily on level 7 fueling as well. So super happy about it .
TL DR - purchased a bs6 rc390. Had power and stalling issues . Got the performance air filter and piggyback fuel mod to alleviate the lean tune from the factory. Bike now runs like a dream.
