the KL was a 60 degree, high cam 45 cu. in. dual carb. ( direct to head), engine with aluminum heads and barrels. developed in the late 40's and early 50's . it's nick name was the "high cam K" in the mid "60s the factory said it over heated so they had to return to a 45 degree 45 cu. in. flat head. it's real problem was racing, it was 45 cu.in. and over head valves , too big for class c ama sanctioned dirt track, and road racing. the only legal ama racing would be TT.
