I have a large collection of Yamaha RD350 RD400 RD250 RD200 DS7 and R5 parts. I have almost any part you could need for these bikes, odds are I have what you need. Send me a text or email with what you need or give me a call. I am glad to ship these parts worldwide and I do accept paypal.
At this time none of the aftermarket expansion chambers are for sale, I will be repairing and repainting all of them before I decide which sets I am going to keep.
Check out my eBay store at the link below, if you see something listed that you would like do not purchase it on eBay. I will give you a discount if we make the deal outside of eBay.
