Hello all,

1st post here on the forum. After months tinkering with the idea to do a complete aesthetic overhaul of my GRiSO 1100, and having decided on DIY, doubts start to acumulate.

I would very much like to build a classically styled metal tank with improved capacity, but as I see from the photos (thanks man!) I understand that replicating the 3D shape of the underside would be a nightmare, and without the wings capacity can only grow up...like blocking-the-view-from-the-road up. So for now I'm going with painting...

Does anyone know what is the tank made of? I'd hate to paint/lacquer it with the wrong materials and discover a few weeks later by having bubbles creeping in or paint flaking off.

Thanks for thy wisdom!

It's certainly made of plastic, of what type would be difficult to determine, but I can't see a problem with paints used on any other plastic body parts.
Problems with plastic tanks are usually caused by what's inside them not external issues.

The GRiSO 1100 ahs a range of around 160/170 miles which ain't bad. I have ridden all over Europe on bikes with a similar range with no problems. I would have thought anyone travelling off the beaten track the answer is to carry extra fuel on a rack or panniers.

Right, found a tank on Ebay, it's on its way, by the time it gets here it'll be late Jan i expect.
Still have to see if the plastic is able to be welded? anyone have first hand knowledge?


The tank is made from Nylon 6 - there will be a mark PA 6 somewhere on the underside, which is definitely weldable

We have 3D printers these days. Someone could print a fuel tank.

I've explored that. It's not that simple.

For my trip to the Arctic Circle it was over 400 km between gas stops. I extended the range by strapping a 1 gallon plastic tank on each side.
The weight was taken by a simple sheet metal plate held with worm drive clips to the foot-peg but they were strapped to the saddle-bags with a Rok strap

Would this sort of tank fit in the wings. About 1.7 liters I think.

If only for one off trips, use a fuel bladder.  A couple of these 6L ones tied to the outside of your gear would probably be as safe as a rigid plastic one.  Unless you backpack them...

The biggest issue as I see it is the frame itself. It would be very hard to build at a k that would *straddle* the frame rails and still be able to use the extra capacity where the wings currently sit.

Range is about 300 Km to empty with a decent map as long as you're not being stupid. If you are being stupid range is considerably less!

So it looks like I've become a fool Wink. When I bought a motorcycle from Canada from Mr. Luka on the pseudo "Omnis" forum, the computer showed me consumption of 6.5 liters per 100 km, at speeds up to 110-130 km/h and I was very satisfied, I would like to point out that the motorcycle was already on Marek's map, but in the next season the consumption increased dramatically to almost 8 liters and after starting there was an unpleasant smell of unburned fuel.My question is that the oil level was a bit too high for some time, but I have already cleaned the filter container, washed the throttles and reset the TPS.I haven't balanced the throttle body yet. Could it be the key one? The parameters are set on the Diag button to 4.8. I know that there can be many reasons, such as the probe, damaged injectors or plugs, or high voltage cables. Thank you for any advice from experts.

Which would suggest as a first indicator an air supply problem. Look on the intake side. Air filter, airbox etc.

The air filter and the entire airbox seem perfect?
