Speedo only went to 80 on those? For one thing it's going to need tires.
Something strange about that speedo, I was sure they went to 120. Maybe a turbo owner can drop a post on us and let us know for sure. I bought my GL650 a year ago next month and it had 2700 on the clock. It still had the original tires and the little rubber tips had not been worn off. No wear but but were they dry rotted, the sides of those tires looked a mud flat that had dryad & cracked in the sun! That was the first thing on my to do list for that bike. It had spent a good part of its life in collector's hands.
