I am from London and am into diesels. I am hoping to build a diesel bike, I lack the mechanical and welding skills that most on here seem to have in abundance, but I more than make up for it with ambition, enthusiasm and gaffa tape/cable ties!
I have been running diesels on vegetable oil and bio diesel for more than 2 years and am pretty active on the scene, if you have any questions about running cars on bio or veg let me know and I will do my best to assist.
Cheers
