Ive done spark plugs and air filter o my 2015 blade today. I couldnt believe how shitty the air filter was as its only been on bike just over 12 months. Guessing thats the joys of riding through winter and in rain etc.
how many miles on the filter. Must say I see little dead flies but lot's of black soote. Do you live in a diesel poluted area??
I’ve recently ordered a Hiflo for my 2016 black edition. Last spring when I looked the one fitted was in a decent condition so I took it out and did a quick blow through to get rid of the surface detritus and put it back, but at £11 it’s not worth messing about https://www.ebay.co.uk/itm/224200752966?ssPageName=STRK:MEBIDX:IT&_trksid=p2060353.m2749.l2649
I watched an episode of Dream Cars and how they're made, featuring the Bugatti Veyron. At full power, the engine consumes 53,000 litres of air per minute. That's about 5 days worth of air for a human.
avoiding city traffic, I mostly collect insects, organic stuff. Every 2 years (about 2k) I vacuun the box & the filter. Yours looks like soote so not sure if it can be vaccumed but worth a try. If the airbox is clean, then the filter is doing it's job. Big but. This also means you have been breathing in all that muck & polution
