Just came across a piece of information.
There is a person named Balu, not his real name, he is an American and a bikes enthusiast, now settled in India. He had started a group here called BulletWallas. It comprises of bullets and other old classic Motorcycles which he also rents to tourists who come to visit India. The head office is in Paharganj Delhi.
This man has modified his old royal enfield quite a lot. The original engine was a 4 stroke 350cc petrol engine. He has installed a 753cc Greeves engine that runs on bio fuel. The bike is now giving an average of 70-75 km/l as compared to 20-30 km/l with the petrol engine. The torque developed by the new engine is quite impressive. He has also installed an ignition system similar to that of a Maruti800 (a car manufactured in India).
He claims that any kind of oil(vegetable/animal fat/used/fresh) can be used to run the bike. It first has to be go through a filter kind of thing provided to you to clean it and then you can put it in your fuel tank.
