I`m also new to the GN. I have been reading up as much info has I can. The GN I just bought is an 85 with 25K original miles and was a 1 owner and has never had a tune-up. I have read up on changing the spark plugs and noticed the recommendations for the extensions. Is it recommended or has anybody moved/removed the hot side piping to change the plugs on the passenger side. I`ve already got the drivers side done. Once I get the basics done I`ll get a plan for a few mods that will not take away from the original value. Thanks
