Since then the Sherpa has reached almost perfect OEM parts and setup, except right side engine paint is peeled. It sat on back of a camper for 20 years, right side out.
I like to bring back to OEM, reversing original owners stuff. Then add what I want which is usually body fitment and carburetors tune
The 89GS took a lot of that, the sherpa less, being a very comfortable bike to start with.
