Hello my bike needs a petrol tank, but I need one to fit under the original fibre glass one, can you please help ? its a montesa cota 247 1972 year

You're thinking of cutting out the bottom of the original tank unit to make it into a cover for a metal tank? Montesa made the 247 in this way, for the UK market at least, later in the 70s but you'd be lucky to find one of the metal tanks they used. Could be a case of getting something made up to fit under the cover or modifying a tank from a small bike or moped. Someone on here suggested rigging up a couple of metal hot drinks flasks under the tank cover, linked by a tube with T-piece and tap, but it sounds a bit fanciful and I'm not sure what sort of filler arrangement could be fashioned.

If you're wanting to move to a metal tank  because of problems with modern fuel and don't want to line the fibreglass tank, may be best to just use a tank from an old Yam TY or similar, and perhaps cut off the seat/side panels section to use separately.

Hi

I used Made In Metal motorcycles to make mine
