I inherited a K&N filter with my 91 Syncro Westy with a carb.  The
filter sits on top of the carb and is a 360 degree doughnut style.
My only power/performance comparison is with a 81 Westy, then a
86 French Syncro Westy Diesel but my 91 seems to have fairly
good power.  I find that cleaning and re-preping the filter is not
much of a pain.   Malcolm S
