Details:

That being said, I am constantly getting new inventory and back filling existing. I don't have a secret stash of extra parts. There may be some shelf wear. The idea is to under promise and over deliver.

I also expect buyer to verify their needs. I aim to please. Aka nos many of these parts have been sitting on a dealers shelves for years, so there may be some dust. There are rare exceptions when I am chasing more inventory where it is not out within 24 hours, but those.

USPS has been known to disappoint from time. If you're not satisfied, I will do whatever can within reason to resolve your concern. Please refer to time frames listed above make your decision and or follow up if not received. If its listed I have it, if not do not it.

Photos are of the item I have available at time photo being taken. The quantity is. These listings have been uploaded with stock photo. In some , I do list of the fitment for parts in title.

This is not trickery, or anything. There is no trickery and/or tom foolery. Regardless of whether the item is loose, bin-filled or individually packaged, I assure you part genuine Yamaha. When I get new inventory, try to list it asap.
