Hi, I just got a 1998 ST1100 and I am doing some work on it to get it ready for my first ride in the spring. I took out the air filter and its pretty dirty. Its pretty heavy and I thought it might be like a resusable one like a K and N but when I ran the number stamped on it (hmmt3 e1) it comes up as the original air filter. Air they cleanable and reusable like a K and N? A K and N one for the bike is over $110.00 in Canada so I would like to reuse the one I have . Thanks for your help and having this forum
