Arfa,
only small concern I have with your post
run your engine on LPG - it has an octane equivalent of 110. = Runs hot with less power.
mine NEVER overheated on Gas - because it was tuned for Gas Performance
TB42 petrol - 93Kw
TB42 Gas Performance - 96Kw
was a far far better machine on Gas than on Petrol I can assure you
