Tacoman:
Well, living on the "wet coast" like you do, you'd know all about rain riding. Here in (more or less) Sunny Alberta, we have to deal with flying grit more than water (except for the monsoon month of June). I never/never/never wash my bikes with a pressure washer.....only with a garden hose, and very carefully at that.
Having said all that, it just makes a whole lot of sense to me to be able to lube the suspension points AT LEAST once a year. Modern bikes impose a whole lot more force on suspension components generally than the old pounders I normally ride so it only makes sense that modern suspensions would need more attention, even ignoring the facts of better design and better materials. A good shot of EP grease in the right places every second month or so couldn't hurt....right??
What kind of marine grease were you using ?? Mineral oil based or synthetic ?? A buddy of mine disassembles and hand greases all his rear suspension points with Amsoil synthetic grease every spring.....which is a big/tedious job. A couple of grease nipples in the right places would turn the "job" into a 5 minute bit of fun. Why, a guy could even do it once a month if he wanted to.
Of course, maybe that's why he no longer has a wife, too....
