Wash it in soapy water and let it dry and re-fit, done that for 2 1/2 years with no problems

Never oiled the filter; have heard of problems starting when the filter has been oiled!

hi, i clean mine in putoline action cleaner and then use castrol filter spray, squeeze the excess off in a paper towel, that way it doesnt get too oily, hope this helps.

cheers

PJ1 filter spray (the B*****ks) and PJ1 spray filter oil

I have used PJ1 Filter cleaner and filter spray without any problems. Currently using petrol and soap and water and shell filter spray for my KTM Enduro.

Surprized a bit here, as you must be in a purely wet(no dust) environment!

The fine summer dust here would saw a piston set in half! The oil is your "catch" for the finer particles!

Fresh oiled filter every time out. I always buy a spare filter so have one in the bike and a clean one ready to go in. Use spray on filter oil (putoline at present ) and wash out with washing up liquid.

With 4RT and a spray filter oil it seems to confuse air sensor and bike is hard to start initially for first few hours as solvent must fill air box. Once started then never an issue. I have started to get into routine of fitting filter to the mesh as soon as I go into the garage for a fettle. Leave on the bench to breath then put in the air box last thing. Seems better that way.
