i have actually done the swap. but had to change the entire rear swing arm assembly from the f2. it was pretty basic surgery(ie little grinding of the frame). the only real con that i have encountered so far is it sits a little(about 1 1/2") lower, causing the bike to stand straight up while on the kick stand. (will have to fix that later) i cannot tell you how she handles, due to the fact i am currently rebuilding the carbs, trying to figure out a drivability ive been chasing before getting side tracted for the swap.(seemed like more fun). ive also seen other posts on this sight with people who have also done the swap, might want to check those out also.
