I have an 05 280 Pro which Iv been riding pretty much constantly since October. I thought that the fuel tap was leaking but I have now discovered that the fuel is leaking all around the seat area due to the padding aroud the air box and seat being soaked in petrol. The leak is not a hole etc as no fuel visibly leaks but the fuel must seem to very slowly seep out of a weld in that area.

Has anyone elso come across this problem?

I dont want to have to buy a new tank as that would be loads of cash but I cant exactly weld it up as one it's aluminium and 2, I dont have a tig welder to hand.

Cheers

Tony

There are several tank sealers that work very well.

Check an aircraft supply place. Those guys can't afford to have it peel off.

I have been using one from a company called "Randolph" for many years with great results.

Whatever you get, be sure it is alcohol resistant.

My son has a 2004 Gas Gas125 Pro. We had the same problem, the petrol weeps from the weld at the seat end of the tank.

I was put in touch with a local welder and that solved the problem.

The fuel tank leak is not exclusive to the 280.We've had two 250's which have both leaked fuel from the poor welding around the bottom end of the tank.Luckily both repaired sucessfully (and cheaply) by a local welding company. It's worth asking around before you think about buying a new tank.

iv got the same problem with my 03 200 and i havnt had it sorted yet. somebody mentioned in a different forum to fil it with arlydite? wil that work

Of course welding is fastest and best.

I was taking him at his word that this isn't an option for him.

It is worth getting a price first for a new tank, from what i remember they are quite cheep about

36 for tank without tap and cap from bvm moto as quoted on here a wile back, and then plus your graphics and yes my mates leaks aswell.

Thanks for the advice. I have used a chemical metal designed for sealing tanks and pipes etc for now so that can at stop my shed smelling of petrol. Somebody mentioned a price of

just noticed my fuel tank on my gasser is split at the bottom too, trouble is the new ones probably just as likely to crack on the weld.Gonna try araldite as i'm riding tomorrow, and see what happens.

My 05 125 gasgas has got a leak in the same sort of area (seat area) it is from the allen screw which goes through the seat to fasten it on, it is to long when bought standered. Welding is the best way and then cut the allen screw down before putting it back in!!!!

Just my 2 cents or phenning or whatever. Pence I guess....

Anyway, as a guy who welds things upon occasion, it seems that there is a problem there, why buy a new one that was likely welded by the same guy and would have the same problem.

If you use some form of epoxy, Ardalite, etc. etc. it can wreak havoc on the poor guy trying to weld it and fix it right later. Sometimes it is tough to get that cleaned out so it does not contaminate the weld.
