Here's a few tips aimed at first time airhead guys.
There are three fasteners holding your valve covers on, not just the big center nut. Can't tell you how many folks start whacking their valve covers without removeing the 10 mm nuts on the back side.
Remove and antisieze your exhaust nuts once a year. If they don't come off, DON'T FORCE, hacksaw a line or drill accross the threads and use a cold chisel to split them off. Forcing them will wreck the threads on the heads, a $125-150 repair.
Remove the battery ground wire before you remove the front cover. Failure to do so and touching the diode board can easily short out and be a $$ repair. JT
