- Thanks for the info Chuck!!
-
- Do you know if the 91' has the 02 style (RXL) heads??? These have
- bigger intake and exhaust ports. If they stayed with the same pipe
- design from the older 89-90 years this may explain the lower HP. My
- sled still has the older 01 style head design. I don't know when
- they started installing the newer ones.
-
- As a side note, if anyones interested in the pipe shootout info for
- the 89 or 90 650's ... I have it. I just don't have anything on DG.
