Hi, it sounds like on paper at least you have a potentially sweet and very expensive engine in that bike, it could be an AMA or factory spec 916R (955) motor but they did have the twin injector setup (which it sounds like you are missing) but in the correct spec from the factory racers of the time should be a 150+ bhp motor potentially. (155 and 153 bhp being quoted but not clear if at the crank/gearbox or wheel) in any case pretty amazing.

At the time they wouldn't have made very many of that spec bike/engine combination at the factory, probably around half a dozen or so for 2 bikes per rider, but if you have all the correct bits, wow?

You do seem to be a bit shy of the 150+ mark though so maybe some of the 955 factory bits are missing? It's unlikely that a remap would add that but even so, a very cool bike. I hope you can check out it's history.

The correct exhaust can add 10% and correct mapping will add a bit more and make it sweeter but I think there's still a way to go potentially even then with this bike.
