Clutch Fluid Issue- 2003 Valkyrie Standard - Updated With Issue.
carolinarider09:
Since I was/am worried about the current clutch master cylinder, I purchased a new one from Partzilla a few days ago. Will install it in the coming week.

I'd take you slave off and look at it. I was losing fluid but no where noticable except that the reservoir would be going well. Pulled the slave off and fluid was all caked on it. I cleaned it and replaced the O rings and now it's all good.

That was my concern as well but I saw no leakage. Since you have personally experienced a similar event, I should now do the same thing.
Are the "O" rings special such that I have to get the "Honda" part? Or this there another option?
h13man:
Metric o'rings are different in sizing. What I can remember, the actual thickness/cross section are different enough to effect the sealing properties. You can swap sizes but I wouldn't w/o careful measuring and the use of it being compression or OD/ID sealing. Unless I was out in the middle nowhere, no choice and/or if it would interchange, then I would but in the shop, nah.

Yes. There are US O-ring sizes that "kinda work" on a Honda, but are not really correct. You can look at the O-ring sizes on the parts diagram and order from a source like this:
