We used this bike for kart-track and WERA Mini racing. It runs very strong and it is super fun on a kart or big track. The bike is located in NorCal https://www.ebay.com/itm/295083499485 Over 50 photos here: https://honda-rs92.alonsos.co/
Couldn't tell from the pictures but the frame front engine mounts weren't hacked for the engine transplant? Many were. Nice looking bike.
