I recently had my '09 KX-R 2wd converted to GAS. So far I'm loving it, and have no complaints or regrets....(57.9c per litre last night in Melbourne). What Im interested in working out is what sort of economy figures I'm getting. I know I'm supposed to get around 35% less economy using gas but how do I go about calculating my figures (made more difficult as LPGAS doesnt have an accurate guage like petrol tanks do) Any suggestions, or might anyone else who is on gas have done the sums?
