K&N filter OUTTA there!
Looks like the K&N filter plugged up AGAIN ... I'm back to stock, sick of fiddling with this thing. I know you can clean them, but having to do it every oil change ... ! ? !
Background. Stock filter was in there until first major service at 23,000 km and never caused any trouble. I got talked into a K&N filter for the usual reasons. Around 8,000 km later, I started noticing a drop-off in top end power, and after a little bit more time to figure out what the problem was, I determined that the filter was clogged (around 32,000 km). I cleaned it and put it back in. Now, around 37,000 km, the drop-off in top-end power started happening again - first noticed it last night. Today I bought a stock air filter and that's what's in there now. The K&N doesn't look *quite* as dirty as it did last time around, but last time it took a bit of time to figure out what the problem was.
Why do they clog so fast? We have a lot of bugs and sandy roads around here, which doesn't help, particularly at this time of year. But also, before putting the stock filter in, I did a little comparison.
The K&N filter has 23 pleats, counting from one side to the other. The stocker has 67. And the depth of the pleats on the stocker is at least a third deeper. The stock filter has 4 times as much filter element area ... Granted, a lot of the stock pleats are so close together that air might have a tough time getting in between, but still.
No test ride yet ... changing the filter was a one-beer job, and we don't ride for a wee bit after that!
Helibars, MRA screen, Ohlins damper, reversed shift pattern, sorted suspension, braided lines, Michelin Pilot Power, all else stock 'coz it's fast enough!
