I never saw it come up on Adventure Rider. I'll have to check out the thread. Also, I must have read that wrong - I thought it was $220 instead of $220 euros. That makes it more like $300 plus shipping - starts adding up fast. And that's a lot of money to me these days, especially when it's not that much of a problem changing the oem.
Joe, it's better to change the oil and leave the filter for every other oil change. Filters actually filter better the more used they are - you just don't want to let them go too long, otherwise they'll restrict the flow too much and collapse. But for every other oil change, it's fine. And just inspect the O-Ring coming out - if it's compressed - squashed about the right amount - you're good to go.
And I'm with you on the rediculous situation of how difficult we have it changing a dumb filter! I guess it goes to show the rest of the machine must be pretty spectacular if we put up with such nonsense. I'm of the view that nothing on this blasted planet is perfect so the solution is to find what comes closest to my purpose and either suffer the down-side or fix if possible.
Joe, are you talking about the transmission input splines? If it shifts fine, don't worry about them. And I agree there too - it's pretty silly these things can wear out and you don't hear of cars and trucks having this problem. But working as an auto mechanic I was tought to put a very thin layer of grease on the splines when doing a clutch. So that part isn't so different.
But back to the filter thing - I think it's a great idea! If it wasn't so damn expensive, I'd try it out.
