look for 90-91 dr650 parts
i beleive all the plastic and tank are the same
i have been thinking of painting my dr650 plastic and tank to match an sp600
i wonder if the sp/dr600 head flows better than a dr650 head?
the 600 head has dual exhuast ports and the 650 has a single port
i think the cam is the same as well as the head gasket
