    Now you have helped me and others with an approach that may work-:wink:- my fear is if BMW starts a "good will replacement" will I qualify with a patch job unless it's leaking? Of course nobody can help me with this question except BMW--and they of course will sit in the weeds until a tank fails and kills someone.
    Their shaft drive issue on BMW's would fill a book and their answer is, 'there are only limited failures of this part" :freaky

    I was told by the parts guy at the local dealership today that he "thinks" (not 100% sure) but thinks that if a part is replaced by BMW as a warranty repair that you do NOT get the 2-year part warranty. Since it was a warranty repair the replacement/warranty part is only warranted for the rest of the factory warranty ... if true this shoots my plan all to hell...
    :cry

    Anybody know for sure?

    My local dealership in New Mexico stated specifically the 2 years applies. On the second go on the valve cover gasket..... I got the new kit with shorter bolts...., and they mentioned that I had 2 years.....even though I'm out of the factory bike warranty...

    Has anyone had this experience? I bought this bike new, have had it for 9 months and 6000 miles and I noticed the fuel tank appears to be cracking along the top edge. The bike has never been down or ran into. The tank doesn't have a scratch on it. It is just cracking. Thx Stacy

    I saw this in this forum before and it appears indeed that your tank is cracking. I'd go back to your dealer and let it repear under warrenty.

    Its pretty common just search any forum with f800s or f650s on it and you'll find threads about it.

    I keep inspecting mine for cracking (2011 f650gs) but so far so good (knock on wood)

    It happens, I'm on my 3rd on my 2010. The first 2 cracked within 3 months, this 3rd one is a different part and seems to be holding up well at 6 months. All were replaced under warranty.

    Thanks to all, I went by the dealer and they acted like it should have happened months ago. New tank on order under warranty. They did mention that the newest version seems to work better than the old. Once again thanks Stacy

    If you wouldn't mind posting the part number of the tank (should be on the work order) when they replace yours?
    I've heard rumor of a revised-revised-tank P/N

    I've got a poll running over on F800Riders about this subject here "voting booths are open" :D

    I'm on my second tank and it has a small crack in it, which I'll get replaced before the two-year parts warranty expires.

    I was doing a quick inspection last night and noticed my 2009 is starting to crack a bit on the gas cap side. I'm now most likely out of warranty, so my question is: should I bother getting it fixed? I thought this was merely the outer shell of the tank, not the "bladder" which keeps the fuel from leaking out.

    I would hit up the BMW dealer to see if they have any good will left. I am not convinced that these tanks are double walled or there is a bladder. Looking at it I think it may just be a coating that is impervious to gas. Love to get a definitive answer.

    When this started I looked at solutions and found some glues that had promise. Got the tank replaced and went on to worry about something else.

    Damn, add me to the list of those with a cracked tank. My bike is a 2010 F 800gs with just over 2000 mi. It was this thread that got me to inspect my bike. I have an appointment with a dealer this Friday. I hope the replacement an upgrade and the end of this issue. Has the issue of ethanol in the gas been discussed. I also own a Ducati and hang out on the monster forum. Many folks there have newer Ducs with plastic tanks that have swelled. The consensus is that they are swelling due to a the alcohol in the gas. It appears that Ducati hasn't come up with a fix.

    Supposedly Ducati fixed it. Well, sort off. My 2012 Streetfighter supposedly has a smaller tank so it can expand before it deforms the outer shell (the outer plastic shell is what we see on the newer Ducatis).

    I thought about it in the context of the BMW F series tanks. It could be the reason for cracking. If that is the case, ethanol being the reason, it can only happen in the bikes sold in the US (and other countries that add ethanol to gas). Both for the BMWs and the Ducatis.

    2012 f800gs with 8600+. noticed crack on gas cap side starting after Alaska trip... One guy said it was a recall at the dealership, the other said it wasn't but it happens. Things like this make me second guess my choice...does the 1200 have these problems?
