Chris -

I wouldn't and didn't on my 84 westy.  I've been running my 2.1 with 1.9
cooling system for the past 11 years without nary a problem.

See my web page devoted to installing a 2.1 into an 84 (83.5-85 too) for my
tips and tricks:

The only other mod I've made is upgrading the Digijet ECU to the European
Digijet model ($250 I think from Boston Bob), other wise you'd think you
were looking at a 1.9 at first glance.

Sorry, no pics when I did this, too long ago for digital cameras (too much
$$ then).
