Wanted-big tank for my £1500 Africa Twin-or who will enlarge
 

Anyone know a guy(in UK) who enlarges steel tanks?

Touratech do a 40-odd litre one for the Africa Twin. They're at www.touratech.de or www.bracken.co.uk

Cheers

£750 for a fuel tank seems a little bit...so I'm hoping to enlarge the original.

It looks like Cool Karim has enlarged his Tenere tank by welding half a jerrycan on each side. Have a look at http://www.coolkarim.freeuk.com/

It looks uncomfortable - as confirmed by Karim in his 'disaster in the sahara' page - but maybe he'll help you out.
