You know, it's not like Mr Honda is willing to resurrect the manufacture of old discontinued parts. Get 'em while you can and smoke 'em if you got 'em 
They will if demand is high enough! They discontinue parts when the turnover drops below a certain level.
Cheers,
I'd like to think it all boils down to economics, supply and demand, cost vs expense. There's another side of me that thinks Mr Honda and other manufacturers would like to sell new bikes. I'm sure both sides of the equation come into play.
HOWEVER, I BELIEVE THAT MR HONDA SHOULD LOOK AFTER HIS LOYAL FOLLOWERS. Those of us that got him here. Those of us that have THREE of his cars sitting in the garage because of the SOHC750. Those of us that still have his motorcycle after 32.5 years. Let the legend live!!
OPEN CALL TO MR HONDA - If you're not going to make our parts then please turn over the molds, whether through sale or generosity, and other production processes to someone that will! It's not nice for you to do this to us! Oh yeah, don't get pissed with someone like Repro Decals when they try to take care of your loyal followers when you won't. Shame on you for #$%*ing about them making our decals and requiring them to not advertise the fact.
ANYONE KNOW HOW TO GET THIS THREAD TO THE CURRENT GESTAPO AT HONDA!! I'm pissed now.
