Hi, my name is Ben and I just picked up a 1987 Yamaha Radian last week. It has 25k miles on it. This is my first bike and pretty new into the whole world of two wheels. It seems to run pretty well, but the owner told me that she was getting about 30mpg. That seems pretty low to me. i thought these should get mid 40's easy. am i wrong? I take it changing the plugs and wires, along with a new air filter would help a lot, but would it make that much of a difference? while poking around i found the air filter and looked oily & pretty dirty. these aren't oiled filters are they? i would guess the filter is a big part of it. and another thing i noticed was that the little rubber things that are between the head and the carbs is splitting a little, are those the things i have listed on the link below? and if so how hard is it to take them off, put them back on and get the bike started again. sorry about all of the questions, but ya never learn if you don't ask. I am trying to get as much knowledge as possible and do anything i can myself the correct way. Because i know that bike work is expensive. thanks a bunch Ben http://item.express.ebay.com/YAMAHA-YX600-...cmdZExpressItem
