POLL: Plastic tank problems

[pennyrobber]

Maybe we should file a complaint w/ the NHTSA.gov site like the sport classic guys did.
They all seem to be getting new tanks.

Man those sport classic guys are cry babies.

To me, if any of this tank deformation can be proven to cause a gas leak near hot or electrical parts, the NHTSA would slam dunk it.

God forbid.
Don't feel like seeing the Ghost Rides on a Duc.

So according to the poll, about 1/3 are not having problems. 2/3s with some degree of problem is a huge number, you would think that Ducati would just about have to do something. The Sport Classic bikes having their tanks replaced  is encouraging.

Slightly different question here. I bought a used plastic tank from a guy on the list, got a good price and planned to just do a different paint scheme on if for when the mood struck for a different look...Anyway I am now wondering if there is any product like POR-15 or Kreem that might work as a treatment to avoid problems with the extra tank?

Maybe this belongs in a separate thread/poll, but another post got me to thinking:


Of those that are having problems, how many have removed the insulation pad from the underside of the tank?

Is the problem fuel...or heat related?

Guys a suggestion here too.  When saying whether you have the problem or not you should list the following.

Model year
Fuel (with/without corn )
Original tank or not
With/without undertank pad
If distortion has occurred and where
Region of the country (or world)

Tank is longer & wider.  Bars hit tank but lock still works.  Pad on right side barely touchs the frame.

16,000 miles.  Tank pad still in place.

Fuel quality............ who knows here in So Cal

not so sure about por-15 + plastic.
that stuff is best for bare metal application.
also, if it's classic por-15 (and not a top coat like their Black-Kote system), then it's also UV sensitive as well. It will start to look shitty after some hard time in sunlight.

on the other hand, my dad has made patch panels for small holes in the trunk floor of 69 pontiac with POR-15 soaked strips of a cloth... works great.
the stuff is bullet proof.

how much sunlight does the inside of your gas tank get??

My 1986 Ford Ranger diesel's prior (and first) owner converted it to run WVO in 1989 or 90 and he put 280k miles on it driving to McDonalds every week to fill up.  I can burn either SVO or regular petrodiesel with no problems, I just have to add antigel and antibacterial to the SVO.

It has a Mitsubishi 4D55T engine with the original factory seal on it (same rings, valves, etc etc) just replaced the injectors, belts and normal maintenance.

I know some diesel engines have issues with vege oil, but not all do.

Don't forget that Rudolf Diesel designed his engine to run peanut oil. 

That's very cool and don't get me wrong, not every situation is the same. You can get by with it on some older engines like yours and it looks like yours was  broken in before the conversion. On new engines, forget about it. In fact a lot of new diesels have issues with all fuels because of the extremely tight tolerances in engine manufacturing. Trying these alternative fuels on a new engine is a guaranteed disaster.
Trust me, my job is growing because of these issues.

I have a dimple on the top rt. side of my tank. exactly like the two on the left cut-outs, in the ripples. Latch barely scrapes by the ign switch, and its widening.
June 06 s2r 1k w/ 4200 miles. Mostly stock.
Tank probs appeared this past fall all of a sudden.
Loc: VA.
Lives under cover, but outside.
Fuel- you can only get corn stuff here. 
Paint on the right engine case bubbling bad. Rear brake looses bleed every 4 months. If it wasn't so much fun to ride- I'd dump it.

Fuel quality............ who knows here in So Cal

From what I have seen - most carry around 10% ethanol.

My stats:

Model year: S4RS/2007
Fuel (with/without corn) 10% ethanol
Original tank or not: Original
With/without undertank pad: With
If distortion has occurred and where: Yes - right side front, right side mid, right side lower
Region of the country (or world): SoCal

When I took the bike in I noticed 3 spots, a new one has appeared since then
