Air filter

[CarloUK]

Anyone using an aftermarket air filter ? 

At 6k mile service intervals I was thinking of going aftermarket so I could just clean and reuse rather than keep replacing it

I use a Sprint filter in mine....similar to the K&N.....very spendy though.

BMC for me. I bought a Sprint filter but it would not seat nicely at all(the sides were kinda floppy, which I believe ahs been addressed now)

In the past I have used K&N but after more research, they are not as effective at filtering and the cost of regular filters is trivial compared to ownership. The Moto Guzzi community I used to be a part of has to pay particular attention to air filters because of the design of the throttle bodies on the bike and the high possibility of damage to them if gummed up with crap making it through the filter or oil particles getting blown off the K&N into the throttle. So on my XR I will definitely stick with regular paper filters. FWIW.

I'm with Salish, I've used "performance" filters in the past but it's a bit of hassle to properly clean and re-oil, plus you need to buy the cleaner and oil. I've read elsewhere that particularly with motorcycles the OE paper air filters are designed for full flow without restricting performance and better guarantees clean air in your engine. So the cost penalty is marginal and a whole lot more convenient sticking with disposable paper filters IMO.
(and of course technically you should declare the modification to your insurance company)

I'll just say . . . . . . . . .
There's a reason the likes of Phil Crowe uses standard air filters in their race bikes, any gains are so marginal but the damage from potential bigger debris getting through to the engine is much greater.

Have used after market filters for more years than I can remember from K+N to MotoHooligan and currently do on 6 bikes from SuperMoto to K1200 without the slightest problem, but…. they are just part of the jigsaw puzzle and see little point in fitting one with without all the other bits and bobs to go with it so it’s working for a reason,otherwise i’d keep the stocker.

I have a Gen1 Sprint filter and an RR inlet (so you can remove the acoustic inserts) sitting in the garage. PM me if you are in the UK and interested.

Agree with this in principle....many of the Gen-1 BMW RR superbike race teams still use the stock filter, they found little to no difference compared to a "so called" sports air filter when run on the dyno.

For those of us who are a tad closer to motorcycle racing than most, I wouldn’t be holding up teams who use the BM engine for anything….but hey we can all live in hope.

Anyone looking to go the ‘Mod route’ the one plus that hardly ever gets mentioned, the one major plus that all the go faster bits and bobs give is the twist N go flexibility of the motor, Jeeze I can ride mine two up with gear and be down to crawling speed and it’ll still pick up as clean as whistle in 6th.
