Re: spark plugs I'd change the stock plugs now (the platinum pucks sometimes start to fall off practically from day one.) TR-55s gapped at about .050-.055 would be good. Then change them about every 20,000 miles or so. You can just pull one or two and take a look at them every now and then. When the electrodes look worn, change 'em.
BTW, TR-5s are like TR-55s but they come pre-gapped at .039. You want TR-55s.
