F went some way to eliminating the K’s handling madness. Wobbles above the ton and has a fit if braked hard in corners. F1 engines troublesome, with camchain, valve and even primary drive hassles. F2 was variable, lasting for 20-60,000 miles. Both can suffer chronic cutting out in the wet which can’t easily be fixed. Some nicely modded examples on offer.
