I have seen them for both air cooled, and liquid, and own one myself for an 84 R. They are an old school when the 3 wheeler was new pipe. They are an uncommon pipe, more rare then many of the older ones. They are real good in the top end gain, and a little in the middle. You may loose a little bottom end, but who needs that anyways. An old school cool pipe for sure. Is yours for air or liquid?
