We have been using a dual fuel 2000i for 8yrs.
Bought the conversion kit from US Carb
, and self installed, no regrets at all.
Clean,very little exhaust smell, plus the LPG mixture is adjustable for altitude compensation.
I do run on gasoline once in awhile just to ensure both systems are working properly, if you have both, might as well use both. (note petrol shut-off valve & tach/hr meter)

So when is this..."old enough to know better" supposed to kick in?
