I think that 1970 was the only year for the 399 Kohler engine. The 1971 sleds had CCW engines. The Kolher engines were known for overheating. This could explain the vent in the hood on the fan side of the engine. Most Kohlers were re-fitted with a return line on the HR carburetor to prevent vapor lock. Dennis Moore
I was looking at the first photo and thought it was a single cylinder for some reason. And it did not look familiar so i guessed a single JLO for some reason!
After reading your post identifying it as a Kohler, I check out the pics more closely and noticed it's a two cylinder. Still, I haven't seen one on the bubble nose before. It's a good trio of reference photos to have on hand. Thanks.

some of the 71' Mark III and IV sleds still used the chrome Scorpion emblems. This one is a 1970 though with the Kohler. My neighbor has a 71' Mark III with a 493 Hirth. He bought it new. Most of the 71's had the red and white stripe down the back of the seat rest.
