G'day everyone, stoked to be apart of the yamaha club. Just pick up a TX500 Have a bunch of questions that I hope you could help me with. but for now I'll ask just a few. It looks to be sitting for a while without be kicked over. (for who knows how long) We are starting off by replacing the battery/spark plugs. To see if we can get it running. Do you recommend doing anything else before trying to kick it over? At the same time we will run some new oil through it, do you recommend "flushing" the engine first? I have read bad things about flushing engines saying it can damage seals etc. Cheers Aaron
