Aluminium fuel tank

24 posts in this topic

I'm onto this now.

Any info on manufacturers, shops. Found only this site.

Just want to conclude a price range of new and used ones.

Mostly looking on ebay, used at 330$

sth like this.

Which model would it fit, since it has only 2 screws for shrouds, probably all 98 to 02 models?

Quite pricey 695, managed to find 520, Italy.

Still wondering on the approximate fittage of the top pic tank.

The tank illustrated appears to be for a 426 ('00-'02) and if so, I believe it should fit a 400 as well.

that tank in the picture looks like a plastic tank with silver spray paint
How do you explain the welds around the seat platform and shroud mount points? Just because someone was skilled enough to form a curve into the tank sides doesn't mean it's not aluminum.

So why do people want/need an AL tank?

Because they are expensive, some of the pros have used them on works bikes, and very few people have them. There really isn't an advantage, if anything I'd say they are a disadvantage because they can dent. If I mess up a plastic gas tank I can have a new one for $100. I'll stick with plastic.

Octane loss is less, because through plastic, fuel slowly evaporates and becomes poor, in alu it stays ritch. minor but hey...

Some say plastic tank cant be repaired, but alu sure can be welded and also anodized any colour possible.

i noticed the beads but the blotchiness and patches look extremely close to paint, or maybe he painted the tank for whatever reason. but it undoubtedly looks like its been painted.

To me, it looks like hand hammered unfinished aluminum always looks after it's been around a little while.:banghead:

Yup, it's amazing what a skilled craftsman can do with a planishing hammer or "Yodel" machine...look at the windscreen fairings on most fighters from the "century Series" and earlier...all done by hand...

for FI, you will have to have an AL tank...there's a pump in there which must be grounded, and a fuel return that could result in positive pressure if the tank vent plugs.

Also, for "Green Sticker" bikes, Cali now requires a double wall plastic tank to minimize vapor loss thru the plastic (Yamaha WRs have a double wall, Honda uses some kind of coating). An aluminum tank doesn't "bleed"
