I want to do a tune up on my lx450. It looks like it should not be a problem but just wanted to get some pointers. When I time it is there anything I should know, such as vacum hoses and such. I will be replacing spark plugs, distributor cap & Rotor, I am not sure about the wires though. I have 99,000 miles on it now. Also I put on a K&M air filter and it was smaller than the regular air filter, is this okay? Thanks for any input.
