What year Husqvarna engine cars is your favorite?
The early 70's? Smaller transfer ports, The mid 70's a tad larger transfer ports, Late 70's to early 80's? To '81. The location of the cylinder studs were moved to allow a larger bore with larger transfer ports. Older case design.
Life before power valves.
The '82 to '88 newer evolution engine? Larger transfor ports and the largest bores and strokes.
The 81 250 cr probably is as good as it gets in the early case in a 250cc engine. The '78/'79 250OR to me was a eye opener also. Then there was the 390cc as it evolved the transfer ports were larger. The carbs went from a 36mm to a 38mm the larger transfer ports allowed more gas flow.
My first husky was a '83 250wr. It wasn't as spunky as the late 70's engines were. I guess the engine was tamed down do to port timing? The '84 250wr had the cr cylinder and the 250 wr came back to life. I'm not sure how the 82 250wr ran. Newer case. To get a little more hit and zip I guess the hot ticket was to use the cr cylinder on the 250wr tranny.
The evolution really took off in the early 80's till around '86 I guess. Disc brakes, liquid cooled, single shock rear suspension, longer seat protection, bigger bores more hp.
What are your thoughts? Have a different model to talk about, your input?
